Low-voltage experiment conversion plug for handcart circuit breaker

Abstract

The invention relates to a low-voltage experiment conversion plug for a handcart circuit breaker. The plug is characterized in that the a plug comprises an aviation plug, a rectifier bridge circuit isarranged in the aviation plug, the input end of the rectifier bridge circuit is connected to a mains supply power grid through a power transmission line, the positive output end of the rectifier bridge circuit is connected to a first jack, a third jack and a fourth jack, and the negative output end of the rectifier bridge circuit is connected to a second jack and a fifth jack; the aviation plugis internally provided with a sixth jack, a seventh jack, an eighth jack and a ninth jack, the sixth jack is connected with a switching-on control power line, the seventh jack and the ninth jack are connected with a common control power line, and the eighth jack is connected with a switching-off control power line.

Description

technical field [0001] The invention belongs to the technical field of electric equipment detection, and in particular relates to a low-voltage experimental conversion plug for a handcart circuit breaker. Background technique [0002] The low-voltage action test is a key inspection item for circuit breaker power outage maintenance, but for the low-voltage test of the 10kV high-voltage cabinet handcart switch, the traditional operation method needs to open the high-voltage cabinet door, or use the secondary cable pins to connect separately There is a greater risk factor in opening and closing jacks. The operation time is long, the test efficiency is low, and at least two people such as substation operation personnel and professional skilled workers are required to cooperate. This is the weak point of prior art. [0003] In view of this, the present invention provides a low-voltage experimental conversion plug for a handcart circuit breaker; it is very necessary to solve the...
