Switch cabinet and incoming and outgoing line function module thereof

Abstract

The invention discloses a switch cabinet and an incoming and outgoing line function module thereof. The incoming and outgoing line function module comprises a conducting core with an axis extending linearly and a core-penetrating type mutual inductor sleeved on the periphery of the conducting core, the front end and the rear end of the conducting core are respectively provided with a first connection structure and a second connection structure which are serially connected on a main loop of the switch cabinet, the conducting core and the mutual inductor are solidified into a whole through an insulator casted on the outsides thereof, and the surface of the insulator is provided with adaptation holes which are corresponding to the first connection structure and second connection structure respectively and used for leading in an external conductor for conducting electricity and leading out an external conductor for conducting electricity. The core-penetrating type mutual inductor with the conducting core penetrating from the center is adopted in the incoming and outgoing line function module, and is casted into a whole through epoxy resin to form the incoming and outgoing line function module with a CT, space of a cabinet body is effectively utilized by the arrangement, and height of the cabinet body is decreased.

Description

technical field [0001] The invention relates to a power transmission and distribution switchgear. Background technique [0002] The middle-mounted switchgear structure in the prior art is such as a switchgear disclosed in CN 203260933 U. The cabinet body is divided into multiple compartments by wall plates made of steel plates, generally including the busbar room on the top and the circuit breaker room in the middle. , The cable room at the bottom, and the circuit breaker room is equipped with a handcart circuit breaker. The handcart circuit breaker includes a handcart that moves left and right and is assembled on the guide rail in the horizontal direction and a circuit breaker fixed on the handcart. The circuit breaker A set of static contacts whose axis is along the horizontal direction is fixed on the wall plate between the cable room and the circuit breaker correspondingly. Arresters, grounding switches, and primary outgoing cables are connected in rows. Since the outl...

AI Technical Summary

Problems solved by technology

Since the outlet components of the cable room in the prior art, such as transformers, lightning arresters, line banks, static contacts, etc., are discrete multiple devices that realize different functions, it is impossible to realize modularized integrated assembly
