Combined secondary terminal short circuit wiring bar

Abstract

The invention discloses a combined secondary terminal short circuit wiring bar, which is formed by sequentially combining and connecting inserting blocks in any quantity in an end-to-end connecting way, wherein each inserting block consists of a body, a wiring plug, a wiring jack and an elastic copper sheet, one side of each body is provided with an inverted trapezoidal groove, the opposite side of each body is provided with a tooth corresponding to the shape of the inverted trapezoidal groove, the wiring jack and the elastic copper sheet are arranged in each body, the wiring jack is electrically connected with the elastic copper sheet and is electrically connected with one end of the wiring plug, and the other end of the wiring plug is directly plugged and connected onto a secondary wiring terminal in a secondary wiring cabinet. The combined secondary terminal short circuit wiring bar has the advantages that any continuous terminals on a secondary wiring terminal bar can realize short circuit and can be led out to be connected to other positions through external test wires, ingenious and flexible effects are realized, during the wiring operation, the inserting blocks in the required quantity are spliced and are then directly inserted and connected onto the corresponding wiring terminals, the consumption of the test wires is reduced, the operation is simple and convenient, and the risk of error occurrence during the wiring is reduced.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment testing, and in particular relates to a combined short-circuit terminal block for secondary terminals. Background technique [0002] When conducting electrical equipment tests, it is sometimes necessary to short-circuit a number of consecutive adjacent secondary terminals of varying numbers from the terminal block in the secondary junction cabinet. When using traditional test wires for wiring, it is often necessary to use a large number of test wires to connect the secondary terminals one by one. Not only is it inconvenient to operate in the small space in the secondary wiring cabinet, but too many test wires will increase the chance of accidental touch , if the secondary open circuit of the current transformer is caused, personal or equipment danger may also occur. Contents of the invention [0003] The invention provides a combined secondary terminal short-circuit terminal block,...
