Abstract
An emergency tripping device for a switch cabinet is used for controlling a tripping rotation shaft of a high-voltage circuit breaker so as to realize tripping. The device comprises a control arm, a guide pipe, a slider, a fixing part, a control rod and an elastic part. The device is arranged on the inner side of the door of the switch cabinet, can quickly and accurately perform emergency tripping of the high-voltage circuit breaker in the switch cabinet, and has the advantages of simple structure, convenient control, safety, reliability, etc.
Description
Technical field
The utility model relates to the urgent switching-off device of a kind of switch cubicle, especially a kind of switching-off device that is used to control the urgent separating brake of primary cut-out.
Background technology
Known, primary cut-out is installed in the high-tension switch cabinet, when its in normal course of operation, after the appearance catastrophic discontinuityfailure causes the secondary control loop power supply to have a power failure, primary cut-out just can't disconnect the primary circuit by the normal running program, requirement according to electric device " five is anti-", when primary cut-out is in the operating state of normal operation, the cabinet door of switch cubicle is interlocked locking and can not arbitrarily be opened, therefore, must reach control primary cut-out separating brake by the urgent switching-off device on the switch cubicle with the disconnection primary circuit, and existing urgent switching-off device complex structure, install and operation inconvenience.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of simple in structure, easy to operate and safe and reliable switch cubicle urgent switching-off device.
The purpose of this utility model realizes by following technical solution:
The urgent switching-off device of a kind of switch cubicle, the separating brake rotating shaft rotation that is used to handle primary cut-out is characterized in that to realize separating brake: comprise control arm, be connected with the separating brake rotating shaft of primary cut-out, be used to drive the separating brake rotating shaft and rotate the realization separating brake; One guiding body connects vertically and is formed with pilot hole, the vertical connection of madial wall of one end and cabinet door, offer the handle hole of aiming at described pilot hole on the cabinet door, and the diameter of described handle hole is less than the diameter of described pilot hole; Sliding part is mounted slidably in the close pilot hole of cabinet door one side; Fixture is fixedly set in the pilot hole away from cabinet door one side, offers the through hole that extends along the pilot hole length direction on it; Joystick, one end is fixedlyed connected with described sliding part, the other end passes the through hole of described fixture, and can be handled telescopic moving between the primary importance and the second place by sliding part, when described joystick in primary importance, described joystick stretches out and promotes the swing of described control arm and makes the primary cut-out separating brake, when described joystick in the second place, described joystick withdrawal is in initial position; Elastic component is arranged in the pilot hole between sliding part and the fixture, is used to make described joystick to be in the second place.
Further, described fixture is that outer peripheral face is formed with externally threaded cylinder, the pilot hole inwall of described body is formed with the internal thread that cooperates with described fixture external screw thread, and described fixture is fixedly connected in the pilot hole of described body by described internal and external screw thread.
Further, the end face of described fixture is provided with to install and uses handle hole.
Further, the external diameter of the through hole of described fixture and described joystick is suitable.
Further, be formed with the pin-and-hole that laterally runs through joystick on the described other end of described joystick, be equipped with a split pin in the described pin-and-hole.
Further, described control arm one end is formed with an installing hole, and described installing hole is sheathed in the separating brake rotating shaft of described primary cut-out, and is locked by bolt.
Further, described control arm is provided with the handle portion that is oppositely arranged with described joystick, and described handle portion is a platy structure.
The utlity model has following beneficial effect:
When the secondary control loop of switch cubicle breaks down, in the time of need carrying out urgent separating brake to primary cut-out, only need to promote sliding part by the operation hole on the cabinet door, joystick is stretched out and promote the separating brake shaft swing of the handle portion of control arm around primary cut-out, carry out separating brake to drive separating brake rotating shaft rotation, the thrust of cancellation sliding part behind the separating brake, joystick is withdrawn under the effect of spring and is resetted handiness; The utility model is made up of control arm, guiding body, sliding part, fixture, joystick and spring, and above-mentioned each part is all simple in structure, with low cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to shown in Figure 1, the urgent switching-off device of a kind of switch cubicle, be installed on the cabinet door 9 of switch cubicle, separating brake rotating shaft 2 rotations that are used to handle primary cut-out are made up of control arm 1, guiding body 4, sliding part 5, fixture 8, joystick 6 and spring 7 to realize separating brake.
Working method of the present utility model is: when the secondary control loop of switch cubicle breaks down, in the time of need carrying out urgent separating brake to primary cut-out, only need to promote sliding part 5 by the operation hole on the cabinet door 9 91, the handle portion 11 that joystick 6 is stretched out and promote control arm 1 is around separating brake rotating shaft 2 swings of primary cut-out, carry out separating brake to drive separating brake rotating shaft 2 rotations, the thrust of cancellation sliding part 5 behind the separating brake, joystick 6 is withdrawn under the effect of spring 7 and is resetted, and handles very convenient.
The above, only for preferred embodiment of the present invention, so can not limit scope of the invention process with this, i.e. the equivalence of doing according to the present patent application claim and description changes and modification, all should still belong in the scope that patent of the present invention contains.
