Abstract
The utility model relates to an indoor high voltage isolate switch with an earthed knife, which is characterized in that the indoor high voltage isolate switch with an earthed knife is added with a three-phase earthed switch, a link cam mechanism, and a hand-operating mechanism based on an existing isolate switch. The hand-operating mechanism drives the link cam mechanism to control the switch, so that the isolate switch is combined with a main body when separated from a ground wire, or the isolate switch is separated from the main body when separated from the ground wire, or the isolate switch separated from the main body when combined with the ground wire. The isolate switch has the advantages of compact structure, reasonable design, convenient use, easy maintenance, and safe performance, and the isolate switch can completely replace existing isolate switches to be used in power systems.
Description
The utility model relates to a kind of indoor high-voltage isolating switch with the ground connection cutter.
As everyone knows, existing indoor high-voltage isolating switch only plays the isolation fracture effect, when carrying out overhaul of the equipments, needs other hanging earthing conductor.Since no any chain between earth connection and the isolating switch, so cause misoperations such as switching on earth wire and charged hanging earthing conductor easily, cause the generation of serious accident.
The purpose of this utility model is to provide the indoor high-voltage isolating switch of a kind of simple in structure, reasonable in design, easy to operate, function admirable, safe and reliable band ground connection cutter, to overcome the deficiency that existing isolating switch exists, prevents that the people from being the generation of contingency.
The utility model is on the basis of existing indoor high-voltage isolating switch, increasing a three-phase earthed switch and a cover connecting rod cam mechanism and man-operating mechanism forms, by the action of man-operating mechanism drivening rod cam mechanism control switch, make switch realize that the master divides with closing or main ground branch or the main function of closing of dividing with dividing.
Specific embodiments of the present utility model is below in conjunction with description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of pull bar in the utility model man-operating mechanism.
---ground connection cutter shaft 2---connecting lever wherein: 1
3---distortion cam 4---rotation axis
5---connecting rod 6---interlock plate
7---isolating switch cutter shaft 8---isolating switch pedestal
9---connecting rod 10---interlock plate
11---arm-tie 12---rear base
13---handle 14---hand lever

The preceding base of 16---rotation axiss 17---
18---earthed switch dowel hole 19---earthed switch dowel hole
20---garden arc groove 21---garden arc groove
Referring to accompanying drawing, the utility model is made up of isolating switch and connecting rod cam mechanism and man-operating mechanism three parts, ground connection cutter shaft 1 and rotation axis 4 are housed on 8 on the pedestal of described isolating switch, at ground connection cutter shaft end connecting lever 2 is housed, rotary shaft end is equipped with distortion cam 3, and connecting lever 2 be enclosed within the distortion cam 3 on the institute open in the arc groove of garden, rotation axis 4 is connected by connecting rod 5 with isolating switch cutter shaft 7; Have dowel hole 15,18 on the base before in man-operating mechanism, on the rotatable lamella dish of hand lever 14 lower ends corresponding to dowel hole 15,18 places have respectively dowel hole 15 ', garden arc groove 21 and dowel hole 19, garden arc groove 20; Interlock plate 6 in the connecting rod cam mechanism is connected as a single entity by connecting rod 9 with the interlock plate 10 in the man-operating mechanism.
The existing division of the course of work of the present utility model is as follows:
One, man-operating mechanism:
As shown in drawings, hand lever 14 is in first gear (the promptly main state that divides) with closing, and at this moment, bolt has pin in the dowel hole 15, and switch is locked.When transfering to the isolating switch pin, downwards during actuating hand lever 14, do not slide in the garden arc groove 20 of the ground connection plug-in strip pin of Bo Chuing on the rotatable lamella dish of hand lever 14 lower ends, until the termination, at this moment, also in the effect of spring fell into garden arc groove 21 on the rotatable lamella dish, switch was locked the isolating switch pin once more, promptly is in second gear (the main ground that divides divides a state).Transfer to ground connection plug-in strip pin, continue downward actuating hand lever 14, do not slide in the garden arc groove 21 of the isolating switch pin of Bo Chuing on the rotatable lamella dish of hand lever 14 lower ends, until the termination, at this moment, ground connection plug-in strip pin also falls in the location hole 19 in the effect of spring, and switch is locked, promptly is in third gear (the main state that closes) with dividing.
Two, connecting rod cam mechanism:
When the interlock plate in the man-operating mechanism 10 rotates counterclockwise by connecting rod 9 drive interlock plates 6 and rotation axis 4, isolating switch cutter shaft 7 also rotates counterclockwise, at this moment, slide in the garden arc groove that connecting lever 2 on the ground connection cutter shaft 1 is opened on distortion cam 3, ground connection cutter shaft 1 does not change, (switch is in second gear), be rotated further rotation axis 4, connecting lever 2 on the ground connection cutter shaft 1 enters the crooked position of the garden arc groove of opening on the distortion cam 3, ground connection cutter shaft 1 is driven rotates counterclockwise (switch enters third gear), at this moment, quadric chain makes isolating switch cutter shaft 7 only do a small amount of swing near the dead point.
In sum, the utility model has been owing to taked a series of technical measures, thus have compact conformation, reasonable in design, easy to use, safeguard easily, the characteristics such as performance safety is reliable, can replace existing old-fashioned isolating switch fully and be widely used in power system.
