Abstract

The invention discloses a multi-core cable voltage test conversion device which comprises a low voltage terminal and a high voltage terminal. The low voltage terminal is provided with at least two groups of low voltage control circuits. Each of the low voltage control circuits comprises a voltage test or grounding bidirectional selection switch, an electromagnetic induction control loop which is connected with the switch, and a corresponding display circuit. The high voltage terminal is provided with high voltage switching voltage test circuits whose quantity is same with the quantity of the low voltage control circuits, and each high voltage switching voltage test circuit is corresponding to a low voltage control circuit. Each high voltage switching voltage test circuit is composed of a normally open switch and a normal closed switch, and an output terminal of the normally open switch is connected with an input terminal of the normally closed switch. Each normally open switch input terminal is connected with a high voltage test stand, and an output terminal of the normally closed switch is grounding. In each group of high voltage switching voltage test circuit, one end of a tested cable is connected with a high voltage contact point between the normally open switch and the normally closed switch. The normally open switch is correspondingly cooperated with the corresponding electromagnetic induction control loop to open or close the normally open switch. The invention has the advantages of convenient operation, time saving, safe operation and the like.

Description

technical field [0001] The invention relates to cable high-voltage test conversion equipment used in the field of cables, and more specifically relates to a multi-core cable pressure test conversion equipment. Background technique [0002] At present, when the traditional cable pressure test is used to test the cable, after the test of a cable core, it is necessary to continue to manually connect the second core to be tested with high voltage for testing, and it is necessary to repeat the above steps for manual testing. . Adopt above-mentioned test procedure, its operation is cumbersome, not only consumes time but also has potential safety hazard. How to overcome the above-mentioned technical difficulties has become an urgent problem to be solved. Contents of the invention [0003] The object of the present invention is to provide a multi-core cable pressure test switching device which is convenient to operate, saves time and is safe to operate. [0004] In order to ach...
