Abstract
The utility model relates to a fitting structure of a high voltage switch cabinet, in particular to a grounding switch interlocking device. The device comprises a cam that is positioned in the switch cabinet and installed on an operating shaft of the grounding switch; the edge of the cam presses against the upper end of a lock pin vertically arranged; the lock pin is inserted in a guide hole of a support and can move up and down, and the support is installed on the inner wall of an upper door plate; a compression spring is sheathed on the lock pin and is pressed between the support and a limit part on the lock pin, and the spring force of the compression spring can cause the lock pin to move upwards; a lower door plate is arranged below the upper door plate, a horizontal partition plate on a frame of the switch cabinet is between the upper door plate and the lower door plate, and the upper edge of the lower door plate is provided with a flange parallel to the horizontal partition plate; and the horizontal partition plate and the flange are provided with through holes right opposite to the lock pin. When moving downwards, the lock pin can pass through the through holes in the horizontal partition plate and the flange. The device is simple in structure, good in safety and capable of simultaneously interlocking the upper and lower door plates on the switch cabinet.
Description
Technical field
The utility model relates to the accessory structure of high-tension switch cabinet, specifically is a kind of earthed switch interlock.
Background technology
In the high-tension switch cabinet, essential when equipment overhauls in to cabinet earlier with the earthed switch combined floodgate, to guarantee the fail safe of maintenance process, therefore before closing a floodgate, earthed switch do not allow to open the upper and lower door-plate of cabinet, need interlock by interlock.Existing interlock exists complex structure, poor reliability or only can be to the defectives such as imperfection of interlocking, interlock of door-plate down mostly.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of simple in structure, fail safe good, can be simultaneously to switch cashier's office in a shop, the door-plate earthed switch interlock of interlocking down.
Earthed switch interlock of the present utility model includes one and is positioned at switch cabinet and is installed in cam on the earthed switch operating axis, cam edge is pressed over a lock pin upper end that vertically is provided with, lock pin interts in the pilot hole of support and can upper and lowerly move, and support is installed on the door-plate inwall; Be with a compression spring on the lock pin, the compression spring is crushed between the stop portion on support and the lock pin, and the spring force of compression spring can make lock pin move up; Following door-plate is positioned at the door-plate below, it between the upper and lower door-plate horizontal baffle on the frame by switch cabinet, the upper edge of following door-plate has the flange parallel with horizontal baffle, on horizontal baffle and described flange, have through hole, when lock pin moves down, can pass the through hole on horizontal baffle and the flange over against above-mentioned lock pin.
The utility model can be in earthed switch action on door-plate and play door-plate interlock, safe, its simple in structure, reliable in action simultaneously, its most of drive disk assembly is installed in dismountable going up on the door-plate, has made things convenient for to install and overhaul.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, this earthed switch interlock includes one and is positioned at switch cabinet and is installed in cam 2 on the earthed switch operating axis 1, cam edge is pressed over lock pin 3 upper ends that vertically are provided with, lock pin interts in the pilot hole of support 4 and can upper and lowerly move, and support is installed on door-plate 5 inwalls; Be with a compression spring 6 on the lock pin, the compression spring is crushed between the stop portion on support 4 and the lock pin 3, and the spring force of compression spring can make lock pin 3 move up; Following door-plate 7 is positioned at door-plate 5 belows, is the horizontal baffle 8 on the frame by switch cabinet between the upper and lower door-plate, and the upper edge of following door-plate 7 has the flange parallel with horizontal baffle 9, has over against the through hole of lock pin 3 on horizontal baffle 8 and flange 9.
When earthed switch during in the separating brake position, to pressing down, the through hole on horizontal baffle and the flange is passed in the lock pin lower end to cam 2 with lock pin 3, upper and lower door-plate is worn with fixing horizontal baffle linked up, thereby can't open upper and lower door-plate;
When earthed switch during at closing position, end in contact on the less part of cam 2 radiuses and the lock pin 3, lock pin resets under the effect of spring force, withdraws from the through hole on horizontal baffle and the flange, at this moment upper and lower door-plate can be opened.
