Description

Mechanical and electric interlocking device for electrically operated drawer

Technical Field

The utility model relates to the technical field of electrical control, in particular to an electrical interlocking device of an electrically operated drawer machine.

Background

The utility model relates to a low-voltage switchgear, especially a MNS drawer cabinet that built-in electrically-operated moulded case circuit breaker realizes interlocking. The related standards of the low-voltage switch cabinet stipulate that a molded case circuit breaker arranged in a drawer cabinet must be reliably interlocked, namely, the drawer cannot be pulled out (a contact cannot be disconnected once) under the condition of closing in the cabinet, and the circuit breaker must be disconnected firstly when the drawer is pulled out. And the breaker cannot be pushed to the working position when being closed. The interlocking mechanism of the drawer cabinet of the domestic common low-voltage switch cabinet completely meets the standard, but the design is limited to the common manually operated common plastic shell circuit breaker (when the circuit breaker is in the working position, the drawer is locked by the interlocking plate and can not be pulled out of the working position, the drawer can be pulled out only after the circuit breaker is opened, in addition, in the test position, when the circuit breaker is in the closing state, the big interlocking bottom lock tongue is driven by rotating the handle to abut against the bottom plate of the drawer, and at the moment, the drawer is locked and can not be pushed to the working position.)

In practical use, however, many users demand to install an electric operator on the drawer, so that automatic switching on and switching off can be conveniently realized. However, the problem is that once the circuit breaker of the electric mechanism is installed, the operation mechanism in the drawer is also needed, but the handle square shaft must be eliminated, namely, the operation mechanism is only used for pushing in and pulling out the drawer, and no mechanism is used for locking the circuit breaker. This causes a phenomenon that the drawer can be moved back and forth as it is when the circuit breaker is closed (working position/test position), which violates the principle of prohibiting the on-load switching on and off.
