Abstract
The utility model relates to a valve mechanism for 10kV AC metal enclosed switch equipment, pertaining to electric technology field and comprising an upper valve (1), a lower valve (2) and a shift fork (6). The fork (6) is respectively connected with the lower ends of a long pull rod (4) and a short pull rod (5), the upper ends of the long pull rod (4) and the short pull rod (5) are respectively connected with the upper valve (1) and the lower valve (2); the two sides of the upper valve (1) and the lower valve (2) are movably sheathed on corresponding guide shafts (3). The utility model is characterized in that: the two sides of the upper valve (1) are both connected with bushings (7) used for passing through and installing the guide shafts (3) and the upper valve (1) is movably sheathed on the guide shafts (3) corresponding to the two sides by the bushings (7) at the two sides; the upper part and the lower part of inner flangings at the two sides of the lower valve (2) are respectively connected with guide bushings (8) for passing through and installing the guide shafts (3) and the lower valve (2) is movably sheathed on the guide shafts (3) through the four guide bushings (8) with two at the upper part and two at the lower part. The utility model solves the problem that the existing valve is easy to be jammed to cause misoperation and has the advantages of simple structure and being safe and flexible.
Description
Technical field
The utility model relates to a kind of switchgear safety device, the valve mechanism in especially a kind of high-tension switch cabinet, specifically a kind of 10kV ac metal closing switch gear valve mechanism.
Background technology
At present, along with developing rapidly of network system, the quantity of various switchgears also sharply increases, and power supply-distribution system is to each switchgear requirement also increasingly stringent.For the reliability service that guarantees switchgear and operator's safety.Related standards stipulates that the valve in the various metal enclosed switchgears should have following function:
1, after circuit breaker cart enters the service position by test position, valve will be opened automatically.
2, after circuit breaker cart is deactivated the position, valve will be closed automatically, block the fixed contact box, and satisfy the requirement of IP2X degree of protection, thereby can guarantee Operation and Maintenance personnel's personal safety, can false touch and the fixed contact of charged switch cubicle.
The valve mechanism that at present domestic each big switchgear plant produces mainly is itself to open circular hole by its metallic plate to match with the guide shaft of both sides and move up and down, because the screens phenomenon can take place in this fit system, make the operation of valve very unreliable, have certain potential safety hazard.
Summary of the invention
The purpose of this utility model is very unreliable at the operation of the valve mechanism in present most of switch cubicle, and the potential safety hazard that exists, a kind of flexible operation of design, reliable 10kV ac metal closing switch gear valve mechanism.
The technical solution of the utility model is:
A kind of 10kV ac metal closing switch gear valve mechanism, comprise valve 1, following valve 2, guide shaft 3, long draw 4, short rod 5, shift fork 6, shift fork 6 links to each other with the lower end of long draw 4 with short rod 5 respectively, the upper end of long draw 4 and short rod 5 links to each other with following valve 2 with last valve 1 respectively, the equal movable set in both sides of last valve 1 and following valve 2 is on the guide shaft 3 of correspondence, it is characterized in that described both sides of going up valve 1 all are connected with the sleeve pipe 7 that is used to install guide shaft 3, last valve 1 passes through sleeve pipe 7 movable sets of both sides on the guide shaft 3 of both sides correspondence; The in-flanges of the both sides of following valve 2 respectively be connected with a guide pin bushing 8 that is used to install guide shaft 3 up and down, following valve 2 by on the dual-side up and down each two totally four guide pin bushing 8 movable sets on guide shaft 3.
The described sleeve pipe 7 of going up valve 1 both sides is a steel pipe, and it and last valve 1 are riveted or be weldingly connected; The guide pin bushing 8 that described valve 2 both sides in-flanges are down installed up and down is steel bushing, and it is riveted with following valve 2 or is weldingly connected.
The beneficial effects of the utility model:
The utility model has been done different considerations at the different working condition of valve up and down, last valve is to become an integral body with steel pipe 7 by riveted joint or other connected mode by door-plate. descending valve is to become an integral body with steel bushing 8 by riveted joint or other connected mode by door-plate, thereby can guarantee valve move up and down flexibly, reliable, improved valve mechanism reliability of operation, fail safe greatly.
