Switchgear structural features
Switchgear according to GB3906-1991 and IEC298 Kai mounted in metal-enclosed switchgear standard designed overall by the cabinet and can be removed from part (handcart) composed of two parts. Cabinet structure for the group and Syria, in combination with bolted molding. Metal screens inside the switchgear divided into circuit breaker compartment, main bus room, cable room and relay instrument room. Shell protection grade IP3X, among compartment protection class IP2X, and all grounded metal structure, each compartment main loop exhaust system with separate pressure release channel.
1, the housing and the separator
Switchgear shell and bulkhead are quasi-rolled steel sheet after several control machining and after bending bolted together. Thus assembled switchgear to ensure the unity of the structure size. Switchgear was divided circuit breaker compartment, main bus room, cable room and relay meter room, each portion of a metal plate connected to separate.
2. Used
Used according to the application can be divided into circuit breaker, voltage transformer handcart, metrology handcart, isolating handcart, etc., all kinds of handcarts same dimensions, the same purpose handcart interchangeability. Used in the cabinet have the test / disconnected position and the working position, every position has interlock device to ensure when the trolley can not move in just over two positions.
3, the circuit breaker compartment
Breaker compartment installed in a specific track for the trolley to move. Breaker moves, isolation valve is automatically opened or closed position between the test position and work to protect the staff do not touch live body. Handcart can be operated in case the door closed, the window can be seen by observing the position of the trolley cabinet which also function to see any signs on the trolley.
4, busbar chamber
Main line from one switch to another switchgear cabinet lead by a small line of static contact box branch fixed pipe fixing bus when crossing the adjacent cabinet side. All bus composite insulated manner.
5, the cable compartment
Cables can be installed indoors PT, grounding switch and surge arresters multiple cables.
6, relay room
Relays interior panels and control panel can be installed to protect the element, the second element measurement instrument display, live monitoring displays.
7, interlocks
Switchgear has a reliable interlock device, effectively protect the safety of operating personnel and equipment T;
When the grounding switch is in the OFF position, the trolley to and grounding switch interlock unlocked from the test / disconnected position, earthing switch closing operation can be carried out; handcart position at work, can not be closed grounding switch. Prevent the charged closing earthing switch, grounding switch prevented in the closed position when the trolley moves to the working position.
Used off the device in the test / disconnected position or working position, in order to operate the circuit breaker, and the circuit breaker after closing, the trolley can not move to prevent the live load mistakenly push-pull circuit.
Each cabinet can be installed between the electrical interlock.
8, the grounding device
In the cable compartment, alone with a 6 × 50mm2 ground bus, this bus can penetrate adjacent each cabinet, good contact with the cabinet.
