Description

Technical Field

[0001] The utility model relates to the field of incoming line cabinets, in particular to a low-voltage incoming line cabinet which is easy to maintain. Background Art

[0002] The incoming line cabinet is a switch cabinet that introduces power from the outside. Generally, a 10kV power supply is introduced from the power supply network. The 10kV power supply sends the power to the 10kV bus through the switch cabinet. This switch cabinet is the incoming line cabinet. The incoming line cabinet is the main switch cabinet on the load side. This cabinet is responsible for the current carried by the entire bus. Since the switch cabinet is connected to the main transformer and the low-voltage side load output, its role is important. In terms of relay protection, when the bus or circuit breaker on the low-voltage side of the main transformer fails, the overcurrent protection on the low-voltage side of the transformer must be used to trip the incoming line cabinet switch to remove the fault.

[0003] The existing patent application number is CN 202122439994.5, which discloses a low-voltage incoming line cabinet, which can push and pull the push block through the hydraulic rod, making the extension or retraction of the support frame more automated and convenient for maintenance. However, installing the push-pull mechanism in the incoming line cabinet wastes cabinet space and affects the normal installation of electrical components.
