4. Overall & installation dimension
5. Product Feature
End Carriage Control Panel fixed AC metal enclosed switchgear (short for panel as below) is a new product designed and developed by NANTE MACHINERY, based on the introduction of advanced foreign design and manufacturing technology. It applies to 3.6~12kV three phase AC 50Hz single busbar or single busbar sectional transport, distribution system, as for receiving and distributing power energy, and realize to control, monitor and protect power circuit. It is widely used for power plant, substation, petroleum, metallurgy, chemical, natural gas and other civil field.
6. Structure feature:
1. END CARRIAGE CONTROL PANEL series is metal enclosed fixed switchgear, the body is welded with angle steel and steel board, inner and outer coating is solid by static spray plastic powder.
2. This panel conforms to GB3906 3-35kV AC Metal enclosed switchgear and international standard IEC62271-200 besides, prevent from opening and closing connecting switch with load, prevent from opening and closing circuit bre aker, prevent from entering into interval with electricity, prevent from closing earthing switch with electricity (five protections adopt simple, reliable mechanical interlock device). The power indicator is installed in front of panel which reflect voltage in the side of circuit. When circuit side with electricity, lock the enclosed board and panel door.
3. Same type product and structure component can exchange each other.
1 The inner structure of panel is divided into circuit breaker compartment, busbar compartment, cable compartment ,relay compartment, use steel plate to separate panels. Use eddy current steel plate and epoxy resin busbar bushing to separate panel.
2 The panel adopts cold roll steel sheet and angle steel to weld together, without reticulation fabric, non-flame-resisting materials. Outer insulating creeping distance of components and supporting insulator, pure porcelain insulation 1.8cm/kV, organic insulation 2.0cm/kV.The air distance of phase to phase, phase to earth 125mm. There is an intelligent hygrothermoscope to start or stop heater according to the humiture condition of circuit breaker compartment and cable compartment in panel, Prevent from forming moist and high temperature.
3 There is a viewing port for observing of closed and open position of upper, down connecting switch without open the door. The panel is double maintenance, inspect relay compartment equipments, operating mechanism, mechanical interlock and transmission part in front, inspect main busbar, shunt circuit busbar, cable terminal, connecting switch and earthing switch.
4 Circuit breaker: The circuit breaker is located in the middle part, disconnecting switch and earthing switch and interlock mechanism are above it, and with indicator device, describe open and closed position.
5 Transformer: CT is mounted on the underpart of front side, connect with circuit breaker and connecting switch, main loop without electricity. It can carry out preventive test, inspection and exchange, the secondary wire of CT to earth reliably .
6 Disconnect switch and earthing switch: connecting switch, disconnect switch and earthing switch can be seen t hrough viewing port, controlled by a set of manual operating mechanism to assure of program and reliable locking for circuit breaker, disconnect switch and earthing switch, meet the requirement of five protection.
7 Measuring instrument, relay protection, monitor device and auxiliary circuit .
8 Earthing: It takes a consideration of 440mm copper busbar as earthing body along with whole width of all panel extending.
