Description
Technical field
The utility model relates to a kind of mid-cabinet earthed switch and cabinet back door closed block.
Background technology
High voltage electric equipment must possess " five is anti-" functional requirement, simple and reliable earthed switch and cabinet back door interlocking device can effectively " prevent mistakenly entering charged chamber " and " preventing to be with earthed switch to close circuit breaker ", a large amount of uses along with mid-cabinet, " five the is anti-" blocking function at its earthed switch and cabinet back door also is gradually improved, but all has problems such as parts are many, installation is loaded down with trivial details, versatility difference.
Summary of the invention
The utility model relates to a kind of mid-cabinet earthed switch and cabinet back door closed block, and it is not only simple in structure, and is easy for installation, and can prevent mistakenly entering charged chamber and prevent to be with earthed switch to close circuit breaker.
The utility model has adopted following technical scheme: a kind of mid-cabinet earthed switch and cabinet back door closed block, it comprises the interlocking block, in the stop body of interlocking block, be provided with groove, the operating axis of earthed switch stretches in the groove, between operating axis and stop body, be installed with connector, operating axis is connected with stop body by connector, stop body can endwisely slip along operating axis, in groove, be provided with back-moving spring, back-moving spring is between the bottom of operating axis and groove, appearance in stop body is provided with convex shoulder, is provided with locking bolt in the bottom of stop body.
Described connector is a connecting pin, and connecting pin is a radial peg.Described convex shoulder is the square convex shoulder, and the shape of square convex shoulder is corresponding with the square hole at switch cubicle rear portion.Described locking bolt is an oval shape locking bolt, and the lockhole position on oval shape locking bolt and the switch cubicle back door is corresponding.
The utlity model has following beneficial effect: the utility model comprises the interlocking block, on the interlocking block, be provided with the square convex shoulder, be provided with oval shape locking bolt in the interlocking stop bottom, when earthed switch closes a floodgate, oval shape locking bolt on the interlocking block is in vertical position, consistent with the hole site of locking, back door, the back door can be opened, the interlocking block is at the square convex shoulder on it under the effect of spring just in time in the square opening at cabinet, the earthed switch operating axis cannot rotate, earthed switch can't separating brake, and another closed block on the earthed switch operating axis stops circuit breaker cart to enter into the service position simultaneously, effectively prevents to be with earthed switch to close circuit breaker.When shutting the cabinet back door, the back door presses the interlocking block, square convex shoulder departs from the square opening of cabinet, the earthed switch operating axis can rotate, and earthed switch can be operated to the separating brake position, and the oval shape locking bolt on the interlocking block is horizontal, vertical with the hole site of locking, back door, the back door can't be opened, and this moment, circuit breaker cart can enter into the service position, had effectively realized the function of " preventing mistakenly entering charged chamber ".The utility model is not only simple in structure, and practicality is good.
