Model and its meaning
The switchgear is a metal enclosed box-type fixed structure, which adopts aluminum-zinc sheets to be processed and assembled by CNC machine tools. It has high dimensional accuracy, short production cycle, and good mechanical strength; small size, light weight, and strong series And versatility, the internal installation board is galvanized, the circuit breaker is fixedly installed, the operation is safer, the reliability is high, and the protection level reaches IP30.
The switchgear is a metal enclosed box-type fixed structure, which adopts imported aluminum-zinc plate (or high-quality cold-rolled steel plate) to be processed and assembled by CNC machine tools, with high dimensional accuracy, short production cycle, good mechanical strength, and internal mounting plate With galvanized treatment, the circuit breaker is fixedly installed, and the operation is safer and reliable.
The upper part of the back of the switchgear is the main busbar room, and the upper part of the room is equipped with a pressure release device; the front upper part is a low-voltage room, and the small busbar can be connected from the bottom of the room with cables, or copper pipes or copper rods can be arranged on the top of the room; switchgear The middle and lower parts are through, and the busbar compartment is electrically connected to the middle and lower parts through the load switch; the rear is installed with current transformers, voltage transformers, and lightning arresters, and the primary cables are discharged from the lower part of the cabinet; the grounding busbar is arranged at the bottom of the cabinet, which runs through the entire row of switch cabinets .
The switch cabinet is composed of 4 parts: ①Bus room ②Three-station load switch room (or circuit breaker room) ③Cable room ④Low voltage control room and measurement or metering circuit, operating mechanism, interlocking mechanism and other parts . Cabinet layout: the upper part is the busbar room and the instrument room, the instrument room is in the front part of the busbar room, and the middle part is the load switch room. The compartments are separated by steel plates to prevent the fault location from affecting adjacent rooms.
