Abstract

The invention aims to provide a safety protection emergency switch-on / off device with the automatic closing function. When the switch-on / off is needed, a lead screw is inserted into an insertion hole.A cover plate is pushed rightwards by the lead screw through a through hole, so that the lead screw enters a box body for realizing the switch-on / off operation. At the moment, a spring is in an expanded state. When the lead screw is pulled out, the cover plate returns to the initial position to block the through hole due to the action of the spring. In this way, the automatic closing function isachieved. An outer column and an outer hole are arranged. When the switch-on is not needed, an insertion column is inserted into the outer hole from the upper portion of a longitudinal channel to block the outer hole. The random insertion of the lead screw is avoided, and the operation is convenient. The working efficiency is improved.

Description

technical field [0001] The invention relates to the field of emergency opening and closing of circuit breakers, in particular to a safety protection emergency opening and closing device with an automatic closing function. Background technique [0002] At present, my country's urban rail transit system is powered by DC system. However, most of its DC power supplies are provided by high-power silicon rectifier devices. Due to the low overload capacity of silicon rectifier device components, the requirements for DC power grid protection components are higher. Quickly analyze the important components in the rail transit of the DC special circuit breaker. The circuit breaker is placed in the box. When the opening and closing operation is required, the box door needs to be opened for operation, or a hole is punched from the box door, and the screw is inserted from the hole for operation. , the hole needs to be closed. Therefore, it is necessary to solve this problem. Contents...
