Abstract
The utility model discloses an earthing switch and a back-lower gate interlocking mechanism of a medium-voltage aggregated switchgear, which can solve the problem that the existing interlocking mechanism adopts first-stage driving interlocking, thus having high cost. An operation large shaft is connected with the earthing switch; the earthing switch and the operation large shaft of the switchgear are riveted with crank arms; each crank arm is connected with the upper end of a driving shaft through a revolving pull head; the lower end of the driving shaft is connected with the pull head; the pull head is connected with an interlocking shaft; the interlocking shaft is fixed on the switchgear through a support; the front end of the interlocking shaft is welded with an interlocking plate; and the interlocking plate is interlocked with an interlocking bent plate welded on a back-lower gate plate. The utility model adopts double-stage drive, can realize the interlocking between the earthing switch and the back-lower gate plate of the switchgear, has simple mechanism operation and low cost, and can reduce the width of switch equipment.
Description
Technical field
The utility model relates to a kind of medium voltage switchgear equipment operation necessary " five anti-interlockings " structural element, is pressed into cover switch cabinet grounding switch and back Xiamen interlocking device in specifically a kind of.
Background technology
Earthed switch is the main element of switchgear, occupies considerable status in the overall formation of switchgear.Switchgear requires earthed switch to close a floodgate under inspecting state, makes equipment ground, to guarantee maintainer's safety; Equally, when equipment is in running status, promptly during the earthed switch separating brake, do not allow to open the back door-plate down of switchgear.
Existing interlocking device adopts the one-level transmission, will have two problems, and the one, in order to satisfy the Insulation Problems in the switchgear, both creepage distance will reach, just need widen cabinet is wide, the cost of switchgear increases like this, also makes the switchgear of equal specification compare the wide of other producer simultaneously; The 2nd, if it is wide not increase cabinet, satisfy the Insulation Problems in the switchgear, both creepage distance will reach, and just need take other insulation measures, and was more loaded down with trivial details like this as increasing insulating barrier or insulating rod pipe etc., and the electric property of switchgear neither be very high.
The utility model content
The utility model provides and has been pressed into cover switch cabinet grounding switch and back Xiamen interlocking device in a kind of, adopts one-level transmission interlocking to have the high problem of cost to solve existing interlocking device.
The utility model operation macro-axis links to each other with earthed switch, connecting lever is equipped with in riveting on switch cabinet grounding switch and operation macro-axis, connecting lever is connected by the upper end of rotation pull head and power transmission shaft, the lower end of power transmission shaft links to each other with pull head, pull head is connected with interlocking shaft, interlocking shaft is fixed on the switch cubicle by support, and the interlocking shaft front end is welded with interlock plate, the interlocking bent plate interlocking that welds on the door-plate under interlock plate and the back.
The utility model adopts the two-stage transmission, can be grounded switch and switch and establish behind the cabinet interlocking of door-plate down, and it is simple to operate to have a mechanism; Cost is low, and the width of switchgear is reduced.
Below in conjunction with accompanying drawing the utility model is described further.

Embodiment
The utility model operation macro-axis 1 links to each other with earthed switch 5, connecting lever 4 is equipped with in riveting on switch cabinet grounding switch 5 and operation macro-axis 1, connecting lever 4 is connected by the upper end of rotation pull head 3 and power transmission shaft 2, the lower end of power transmission shaft 2 links to each other with pull head 6, pull head 6 is connected with interlocking shaft 8, interlocking shaft 8 is fixed on the switch cubicle by support 7, and interlocking shaft 8 front ends are welded with interlock plate 11, interlocking bent plate 10 interlockings of welding on the door-plate 12 under interlock plate 11 and the back.
When the operational grounding switch, earthed switch operation macro-axis 1 drives power transmission shaft 2 by connecting lever 4 and rotates, and like this, earthed switch operating axis 1 rotates 180 °, and interlocking shaft 8 rotates 90 °.When the earthed switch separating brake, interlock plate 11 hooks interlocking bent plate 10, and back door-plate 12 down can not be taken away from the switch cabinet; When earthed switch closed a floodgate, interlock plate 11 and interlocking bent plate 12 were disengaged condition, and at this moment, back door-plate down can be taken away from the switch cabinet, and the little axle 13 in the backlocking mechanism 9 stretches out under the promotion of spring, stops the rotation of interlock plate 11; When door-plate was opened down behind the switch cubicle, earthed switch can not separating brake.When after after down door-plate 12 is installed on the switch cubicle, the lower edge of interlocking bent plate 10 will promote little 13 indentations in the backlocking, like this, backlocking mechanism will not be related with interlock plate.
