SecoGear™ Comprehensive and Reliable Interlocking System

Metal-clad Switchgear

For personnel safety, SecoGear is designed with a number of comprehensive mechanical interlocks. The mechanical interlocks are designed to prevent: • A closed circuit breaker being racked-in to or racked-out from the connect position • A circuit breaker are being closed on other than connect and test position • A circuit breaker being racked-in to the connect position if the secondary socket has not been plugged/connected • Rack-in of the circuit breaker into the connect position or rack-out from connect position if the door of circuit breaker compartment is opened • Closing of earthing switch when circuit breaker is locked in the connect position • Opening of cable compartment door when earthing switch is in the open position • Disconnecting the secondary socket when circuit breaker at the connect position

Arc-proof Tested

Automatic Shutter System

SecoGear enclosure is designed to meet protection degree of IP4X as per IEC 60529. The grounded metal enclosure protects operators from live parts and moving parts inside the switchgear. The enclosure is sealed to eliminate penetration of external objects, which may cause short circuit of the system. The metal-clad design, sturdy door hinges and lock system, enabled SecoGear to successfully internal arcing test in accordance to IEC 62271-200 in all its three primary compartments.

SecoGear metal-clad switchgear is equipped with an automatic grounded metal shutter each for bus and line/load in front of its primary disconnect bushing. When the breaker is in the test or disconnect position, the shutter will automatically close and lock to provide the designed IP protection and preventing operator from mistake-opening the shutters which may cause personnel injury during maintenance.

Safety - Pressure Relief Design All three primary compartments of SecoGear are provided with pressure relief flaps, which will automatically open and guide the pressurised gas to the rear side direction if an internal arc-fault occurs in an affected compartment. The pressure relief protects damage to switchgear components and the risk of injury to personnel, which may endanger an operator or extend the arc-fault effect to the entire switchgear lineup.

SecoGear™ High Reliable Components

Metal-clad Switchgear

SecoGear reliability is based on the usage of proven components. All components including the advanced SecoVac embedded pole vacuum circuit breaker, insulating materials, disconnect bushings, inter-unit bushing and instrument transformers have been strictly selected and have been qualified for 40 years lifetime through accelerated thermal aging tests.

Robust Drawout Mechanism SecoGear drawout mechanism is designed to avoid misalignment during racking, therefore overheating of the primary disconnect is prevented. All drawout mechanism is bolted to the enclosure frame with a double bended .

Space Heaters SecoGear offers space heaters at the cable compartment as a standard feature to avoid condensation inside the switchgear due to high humidity. Space heaters should be permanently energized during installation and commissioning period and can be controlled thru humidistat or thermostat after switchgear is in normal operation.

Reliability

Safety

• The 3 primary compartments and 1 secondary compartment are completely self contained and segregated from each other which limits the influence between compartments and prevents spreading of an arc-fault between compartments. • SecoGear is equipped with a Quick-action earthing switch type JN(ESW) with short circuit making capability. • A heat-shrinkable material with high dielectric and strength properties insulates the busbar. • The main busbar is provided with inter-unit bushing to prevent travel of arcing to the entire main busbar of the line-up. • SecoGear is equipped with a highly reliable SecoVac vacuum circuit breaker with excellent electrical and mechanical performance. • Circuit breaker in the SecoGear switchgear has three positions: connected, test and disconnected positions.

SecoGear is designed with a number of interlocking systems to prevent maloperation: • The circuit breaker can only be moved from test to connect position and vice versa when circuit breaker is opened. • The earthing switch cannot be closed when the circuit breaker is in the connect position and in the traveling position between test and connect. • The cable compartment door can be opened only when the earthing switch is closed and at the same time the earthing switch can be opened only when the cable compartment door is closed. • The secondary plug can only be inserted or removed only when the circuit breaker is in the test position. • The circuit breaker can only be closed when the circuit breaker is precisely in the definite test or connection position. • When the circuit breaker is removed from connect position, the metal shutters will close automatically. • The switchgear is internally arc-proof. • All high primary compartments are provided with a pressure relief flaps located on the topside of the switchgear. • Any overpressure inside the compartment by an internal arcing will be released thru the pressure relief flaps.

VT Module There are 2 types of VT modules available on our SecoGear: • Withdrawable VT module with primary fuses for line voltage sensing at the cable compartment of breaker • Withdrawable VT module with primary fuses for bus voltage sensing at metering

VT Module

A special fixed type VT module without primary fuses for bus voltage sensing (mounted on the top of breaker ) is available. This option is intended to eliminate number of vertical sections for dedicated metering . Number of the voltage transformer on the VT module can be 2 or 3 VT depending on the application and requirement. The withdrawable VT module allows replacement of the fuses with the switchgear in service. Truck racking-out with the door closed operates closure of an automatic shutter between the live parts of the switchgear and the VT metering compartment. Surge arresters on a drawn-out VT module and blown fuse indicator switch are as an option.

Voltage Transformer The voltage transformers can be one or two poles type, with performances and accuracy classes suited to the functional requirements of the connected devices. When they are installed on a withdrawable truck they are fitted with primary fuses. The current and voltage transformers are designed to meet or exceed requirement of IEC60044-1 and IEC60044-2 standards respectively.

SecoGear™

Instrument Transformer Metal-clad Switchgear

Current Transformer The current transformer and voltage transformer are cast-resin type instrument transformers for measuring devices and protection devices of indoor application at the frequency of 50 or 60Hz. The instrument transformers are moulded in high quality epoxy resin to have a good performance at high polluted and humid area. The instrument transformer is designed to suit installation in tropical environment and it doesn’t need special maintenance. The instrument transformers can be mounted at any position. The lightweight and small dimensions are the main features of its design. The current transformer secondary terminals are located in recesses either in one or both sides of the transformer base, therefore giving two connection possibilities for installation flexibility. A ring type CT is also available for ground protection devices.

Installation of switchgear In order to obtain an optimum installation sequence and ensure high quality standards, site installation of the switchgear should only be carried out by specially trained, or at least by personnel supervised and monitored by responsible persons. On commencement of installation on site, the switchroom must be fundamentally finished, provided with lighting and the electricity supply, lockable, dry and with facilities for ventilation. It is also required that Figure 1: plane layout for switchgear arrangement

the basic frame and indoor ground of switch should be checked and accepted before the construction. It must be ensured that the ceiling height is sufficient for the opening travel of the pressure relief plates. Tolerances for laying the floor frame are: Evenness tolerance: ± 1mm within a measuring length of 1m. Straightness tolerance: 1mm per 1m, but not more than 3mm over entire length of frame.
