Abstract
The utility model provides a valve mechanism for a 40.5 KV switchgear, comprising supporting plates on the left and right sides, wireline pulley components on the supporting plates, bearing pedestals, roller grooves, and two groups of valve components between the supporting plates. Each of the valve components is composed of a first valve with a rotating shaft on the upper end, and a second valve connected with the first valve via a hinge and provided with a wheel shaft on the lower end, the rotating shaft is matched to the bearing pedestal, the wheel shaft is matched to the roller groove via a roller, each of the wireline pulley components is connected with wheel shaft of the upper end valve component via one end of a wireline, and connected with the wheel shaft of the lower end valve component via the other end of the wireline, one end of a link mechanism is rotatably connected with the wheel shaft of the lower end valve component, and the other end is rotatably connected with a supporting seat. The valve mechanism is simple in processing, high in transmission efficiency and flexible and reliable in motion, and is mainly used for opening and closing a high voltage supply contact in a 40.5 KV switchgear when a handcart goes into and out of the switchgear.
Description
Technical field
The utility model relates to a kind of mechanism that driving activity door curtain opens and closes that is used for, and particularly relates to a kind of 40.5 kilovolts of switchgears and uses valve mechanism.
Background technology
Existing valve mechanism comprises the supporting bracket of and arranged on left and right sides; Be arranged at two groups of valve between the supporting bracket; Connecting lever on one end link to each other with last valve both sides respectively a group; Connecting lever under the one group of roller crank arm mechanism that is connected with the last connecting lever other end, one of which end be connected with following valve both sides respectively one group, the other end of following connecting lever is connected to the same group of roller crank arm mechanism that links to each other with last connecting lever.Shortcoming is that valve adopts the steel plate bending part, the processing technology relative complex, and moving-mass is bigger, adopts many connecting levers kind of drive, and parts are many, and transmission link is complicated, and power transmission loss is big, and it is dumb to move.
The utility model content
The purpose of the utility model is to overcome above-mentioned shortcoming, provides a kind of parts few, and transmission is simple, and reliability is high, and 40.5 kilovolts of switchgears of flexible movements are used valve mechanism.
40.5 kilovolts of switchgears of the utility model comprise with valve mechanism and the supporting bracket of and arranged on left and right sides are arranged on the wireline pulley assembly on the supporting bracket that bearing pedestal and roller groove are positioned at two groups of valve assemblies between supporting bracket.Wherein, valve assembly is provided with first valve of rotating shaft by its upper end, is connected with first valve and the lower end is provided with second valve composition of wheel shaft through loose-leaf; Rotating shaft cooperates with bearing pedestal; Wheel shaft cooperates with roller groove through roller, and the end that the wireline pulley assembly passes through steel wire is connected with the wheel shaft of upper end valve assembly, and the other end through steel wire is connected with the wheel shaft of lower end valve assembly; The wheel shaft of linkage one end and lower end valve assembly is rotationally connected, and the other end and supporting base are rotationally connected.
40.5 kilovolts of switchgears of the utility model with the operation principle of valve mechanism are; When handcart got into switchgear, the roller that is fixed in the handcart both sides promoted linkage and inwardly rotates, thereby the valve assembly that drives the lower end is folding downwards; Simultaneously; The valve assembly that drives the upper end through the wireline pulley assembly is upwards folding, thereby opens valve and expose the high voltage source contact, in order to inserting high voltage source; Otherwise when handcart withdrawed from switchgear, the roller drivening rod mechanism of handcart both sides was to inner rotary; Thereby the valve assembly that drives the lower end is upwards opened; Simultaneously, the valve assembly that drives the upper end through the wireline pulley assembly is opened downwards, and the roller until the handcart both sides breaks away from linkage; Thereby close valve and cover the high voltage source contact, thereby isolated high-voltage power supply.
40.5 kilovolts of switchgears of the utility model are to use collapsible valve with the advantage of valve mechanism, make valve be reduced to steel plate, and processing technology is simple, and has alleviated moving-mass, and it is more laborsaving to move; The utilization of the wireline pulley kind of drive has reduced amount of parts, has simplified transmission link, has improved transmission efficiency.These valve mechanism flexible movements, reliability is high.Open and close the high voltage source contact when being applicable in 40.5 kilovolts of switchgears the handcart turnover, thereby the isolated high-voltage power supply guarantees maintenance and operating personnel's safety when safeguarding.
