Problems solved by technology
Frame circuit breaker is a low-voltage power distribution appliance. When it connects and breaks the short-circuit current, the arc and electromagnetic field generated by it may cause the personnel around the circuit breaker to be injured by the arc and electromagnetic damage. The arc generated by normal current will make the surrounding air quality very poor. However, when equipment maintenance is required, the operator must approach the circuit breaker for manual operation, that is, shake out the circuit breaker to achieve electrical isolation, so that The operator is exposed to the hazards of injury mentioned above
In addition, circuit breakers are sometimes installed in places that are not easy to be reached by people (such as too high, too low or too narrow space), so that it is difficult to manually shake in and out

The invention discloses a drawer-type carrying device, which is used to place a circuit breaker. The drawer-type carrying device includes: a cradle; a handle, which is used to carry the circuit breaker body and is disposed on the cradle in a reciprocating manner; and A transmission mechanism is arranged in the cradle and is used to electrically drive the handle to move in and out. This allows the operator to remotely operate the circuit breaker in and out, which not only facilitates the operator's operation, but also avoids the possibility of the operator being harmed by arc, electromagnetic and exhaust gas due to close operation.
Description
technical field [0001] The invention relates to a carrying device, in particular to a drawer-type carrying device for carrying an air circuit breaker. Background technique [0002] Generally, a circuit breaker installed on a drawer is called a frame-type circuit breaker, which can be carried by a drawer-type carrying device, so that the circuit breaker can be shaken into the drawer for electrical connection or shaken out of the drawer Realize electrical isolation for easy installation and maintenance. Frame circuit breaker is a low-voltage power distribution appliance. When it connects and breaks the short-circuit current, the arc and electromagnetic field generated by it may cause the personnel around the circuit breaker to be injured by the arc and electromagnetic damage. The arc generated by normal current will make the surrounding air quality very poor. However, when equipment maintenance is required, the operator must approach the circuit breaker for manual operation, ...
