Product Details
Main purpose
XGNl7-40.5 box-type fixed AC metal-enclosed switchgear is designed according to GB3906-91 "3—35kV AC metal-enclosed switchgear". Its shell conforms to the IP2X protection level stipulated by GB4208-93. The switchgear is an indoor complete set of three-phase AC 50Hz single busbar and a busbar with bypass system, which is used for receiving and distributing 35kV network power.
Use ambient conditions
a. Altitude: no more than 1000 meters;
b. Ambient temperature: upper limit +40℃~lower limit -5℃;

Main structural features
XGNl7-40.5 box-type fixed AC metal-enclosed switchgear is a fixed structure, and its basic skeleton is welded by copper and steel plate bending parts, and the cabinet shell has a protection level of 1P2X;
The switchgear is mainly assembled from the front cabinet and the rear cabinet, and corresponding functional units are set up according to different purposes. The insulation distance is not less than 300mm, and the internal structure is shown in Figure 1.
3.1 Front Cabinet
The front cabinet is equipped with main busbar and busbar isolation switch room, circuit breaker room, relay room, etc. The main busbar and busbar isolation switch room are above the cabinet, the circuit breaker room is set below the cabinet, and the room is also equipped with current Transformer, the two chambers are separated by an insulating plate and are connected by a busbar bushing.
The relay is set in the middle of the front of the cabinet. There are 15 small busbar terminals in total, and there is no two-wire cable channel. The terminal room is set in the lower left door, which can install JH10 type terminals 80 or more. M12 is also set below the room. The grounding bolts are used for auxiliary circuit grounding, and there is a small door for maintenance access. Above the terminal room is the operation panel, which can be equipped with auxiliary switches.
3.2 Back Cabinet
The rear cabinet is connected to the front cabinet with bolts. The cabinet can be equipped with bypass busbars and isolating switches as required. The overhead incoming and outgoing lines also pass through the cabinet. Small attached cabinet or screen. When the side mother is not set, the overhead incoming and outgoing lines can bePass through the top of the rear cabinet. The cabinet is also installed with voltage transformers or arresters, and the liaison busbar and cable outlet are installed in this cabinet. The rear door is a two-way door structure. If the live display indicates that there is no electricity, the rear door can be opened, and the main busbar room and the rear cabinet are separated by a partition.
