Abstract
The utility model relates to a change-over switch control mechanism for a dry vacuum loaded tap changer, which can enhance the work reliability of the tap switch, and lower the work noise. The utility model has the technocal proposal that the utility model is composed of an insulator, a vacuum switch tube, etc. The utility model is characterized in that a camshaft is provided with a groove cam; a rolling wheel which can slide along the groove of the groove cam is arranged in the groove cam; the rolling wheel is connected with an upper guiding rod of the insulator. The utility model has the advantages of high operational reliability and low work noise.
Description
The utility model relates to a kind of diverter switch controlling organization of dry vacuum on-load operation switch.
At present, the diverter switch controlling organization is made of external cam, insulator, vacuum switch tube etc., and functional reliability is relatively poor, and operating noise is bigger.
The purpose of this utility model is to provide the diverter switch controlling organization of the dry vacuum on-load operation switch that a kind of functional reliability is good, operating noise is less.
The technical solution of the utility model: a kind of diverter switch controlling organization of dry vacuum on-load operation switch, constitute by insulator, vacuum switch tube etc., it is characterized in that: camshaft is provided with grooved cam, being provided with in the groove of grooved cam can be along the roller of its slip, and roller is connected with the top guide bar of insulator.
Advantage of the present utility model: because the utility model cam has adopted grooved cam, the following working face of grooved cam works when drawing back the vacuum switch tube contact, on the contrary, when grooved cam cuts out vacuum switch tube, working face has and helps the vacuum switch tube closure mandatoryly on it, make it work as Kai Zekai, must close when closing.The utility model reliable operation, simple in structure, cost is low, switch active force, grooved cam and roller impulsive force and operating noise are all smaller.
Narrate embodiment of the present utility model in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
Be provided with grooved cam 2 on camshaft 1, being provided with in the groove of grooved cam can be along the roller 3 of its slip, and roller 3 is connected with the top guide bar of insulator 4.The following connector of insulator is by adjusting the contact that screw 5 connects vacuum switch tube 6.During work, camshaft 1 is forward or reverse within the specific limits, drives grooved cam 2 and rotates together, thereby make 4 times connectors of insulator by adjusting the switching of screw 5 pulling vacuum switch tubes 6.
