Abstract
The invention belongs to the electric leakage protection device technical field and relates to an electric cabinet contactor electric leakage protection device. The electric cabinet contactor electric leakage protection device includes two contactors; each contactor is provided with a contact button; the contact buttons are provided with shifting sheets; and the front end surfaces of the contactors are provided with outer covers. According to the electric cabinet contactor electric leakage protection device, the contact buttons are provided with the shifting sheets, so that the contact buttons can be ejected directly in an emergency situation, and therefore, the contactors can be well protected.
Description
Technical field
The present invention relates to the technical field of earth leakage protective device, especially a kind of switch cabinet contactor earth leakage protective device.
Background technology
Contactor in switch cabinet is the state of pressing in contact button under normal circumstances, but the contactor self structure Shortcomings due to existing switch cabinet, therefore contactor is when running into the special circumstances such as short circuit, electric shock, thunderbolt and the running of high-power machine excess load, circuit will occur to be burnt, poor safety performance, easily causes large economic loss.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the problem proposing in above-mentioned background technology; the invention provides a kind of switch cabinet contactor earth leakage protective device; by plectrum is set on contact button; make contactor in emergency circumstances can make contact button directly eject running into, for contactor, play a very good protection.
The technical solution adopted for the present invention to solve the technical problems is: a kind of switch cabinet contactor earth leakage protective device; comprise two contactors; on each contactor, be provided with contact button, on contact button, be provided with plectrum, on the front end face of contactor, be provided with enclosing cover.
Further limit: the middle part phase clamping of plectrum and two contact buttons.
Further limit: cover outward and be provided with the window that can have an X-rayed plectrum and two contact buttons.
Beneficial effect of the present invention: this switch cabinet contactor earth leakage protective device; by plectrum is set on contact button; make contactor when running into the special circumstances such as short circuit, electric shock, thunderbolt and the running of high-power machine excess load; can make contact button directly eject, for contactor, play a very good protection.
