Abstract
The utility model discloses a kind of mounting structure of vacuum switch tube, comprise insulating cylinder, vacuum switch tube, circular slab and socket wrench specially adapted for it, described insulating cylinder bottom is provided with conductor inserts, described circular slab center is provided with the hole clipping identical with vacuum switch tube fixed contact, circular slab circumference is provided with the bayonet socket being evenly distributed, between bayonet socket and hole clipping, be provided with through hole, described circular slab is stuck in by hole clipping on the fixed contact of vacuum switch tube, and described vacuum switch tube fixed contact and conductor inserts are threaded connection; Described socket wrench specially adapted for it bottom is provided with the claw matching with circular slab bayonet socket, and socket wrench specially adapted for it welded top has nut.The utility model advantage is compared with prior art: the mounting structure of the utility model structure is simple, design ingenious, adopt this mounting structure, sealing and the encapsulating that neither can affect insulating cylinder inner member are processed, and can guarantee that again vacuum switch tube is not damaged.
Description
Technical field
The utility model relates to the mounting process of vacuum switch tube, relates in particular to a kind of mounting structure of vacuum switch tube.
Background technology
Vacuum switch tube is the core component of solid insulation ring main unit, and it is an insulation crust made from glass or pottery, in-built radome, dynamic and static contact, and dynamic and static contact lays respectively at the two ends of vacuum switch tube.Movable feeler lever overcoat has the corrugated stainless steel tubing that can contract the second month in a season, and its effect is to guarantee that movable feeler lever keeps the vacuum degree of arc control device while moving within the specific limits, is the emphasis part of vacuum switch tube.While vacuum switch tube being installed in solid insulation ring main unit, if the rotation of the driven contact end application of force likely causes the damage of bellows, only from the stationary contact application of force, rotated installation.At present, Ye You producer adopts from insulating cylinder outside and is screwed into the installation that screw completes vacuum switch tube, but this scheme can affect the sealing of insulating cylinder inside.
In addition, the insulating cylinder inner space of solid insulation ring main unit is narrow and small, and the fixed contact of vacuum switch tube needs to be again connected reliably with the conductor that is embedded in insulating cylinder bottom, and these have brought suitable difficulty for the installation of vacuum switch tube in insulating cylinder inside.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, provides a kind of mounting structure of vacuum switch tube.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of mounting structure of vacuum switch tube, it is characterized in that: comprise insulating cylinder, vacuum switch tube, circular slab and socket wrench specially adapted for it, described insulating cylinder bottom is provided with conductor inserts, described circular slab center is provided with the hole clipping identical with vacuum switch tube fixed contact, circular slab circumference is provided with the bayonet socket being evenly distributed, between bayonet socket and hole clipping, be provided with through hole, described circular slab is stuck in by hole clipping on the fixed contact of vacuum switch tube, and described vacuum switch tube fixed contact and conductor inserts are threaded connection; Described socket wrench specially adapted for it bottom is provided with the claw matching with circular slab bayonet socket, and socket wrench specially adapted for it welded top has nut.
The utility model advantage is compared with prior art: the mounting structure of the utility model structure is simple, design ingenious, adopt this mounting structure, sealing and the encapsulating in vacuum switch tube later stage that neither can affect insulating cylinder inner member are processed, can guarantee that again vacuum switch tube is not damaged in installation process, also can guarantee that vacuum switch tube is connected reliably with the conductor inserts of insulating cylinder inside.

In figure: 1-insulating cylinder, 2-vacuum switch tube, 3-fluid sealant, 4-circular slab, 5-conductor inserts, 6-torque spanner, 7-socket wrench specially adapted for it, the moving contact of 2-1-vacuum switch tube, the fixed contact of 2-2-vacuum switch tube.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figures 1 to 6, the mounting structure of the utility model vacuum switch tube comprises circular slab 4 and the socket wrench specially adapted for it 7 of a particular design.Described circular slab 4 is injection molded by makrolon material, and shape as shown in Figure 5.Merlon has good shock resistance, resisting heat distortion performance, and good weatherability, hardness are high, under the revolving force of 35～40N, can not be out of shape, break, can meet the installation requirements of vacuum switch tube 2, and it is a kind of good fire-retardant, insulating material, staying can not affect withstand voltage, the office of cabinet main body and put performance on the fixed contact 2-2 of vacuum switch tube.The shape of the mid portion of circular slab 4 and vacuum switch tube fixed contact 2-2 fit like a glove, and while being embedded on fixed contact 2-2, can freely not fall.The effective thickness of circular slab 4 is more smaller than the length of the fixed contact 2-2 of vacuum switch tube, can guarantee that fixed contact 2-2 contacts reliably with conductor inserts 5.Socket wrench specially adapted for it 7 is formed by round steel machine work, can put the inside of insulating cylinder 1 into, and its internal diameter is greater than the external diameter of vacuum switch tube 2, is highly greater than vacuum switch tube 2.In installation process, neither can damage vacuum switch tube 2, can not damage insulating cylinder 1 again, the claw of its bottom and the bayonet socket on circular slab 4 circumference match, and on circumference, are decile distribution, can guarantee that circular slab 4 is stressed even in installation process.
Above-mentioned embodiment is exemplary, is to be this patent to be comprised to the restriction of scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do be anyly equal to change or modify, all fall into the scope that this patent comprises.
Claims (1)
1. the mounting structure of a vacuum switch tube, it is characterized in that: comprise insulating cylinder, vacuum switch tube, circular slab and socket wrench specially adapted for it, described insulating cylinder bottom is provided with conductor inserts, described circular slab center is provided with the hole clipping identical with vacuum switch tube fixed contact, circular slab circumference is provided with the bayonet socket being evenly distributed, between bayonet socket and hole clipping, be provided with through hole, described circular slab is stuck in by hole clipping on the fixed contact of vacuum switch tube, and described vacuum switch tube fixed contact and conductor inserts are threaded connection; Described socket wrench specially adapted for it bottom is provided with the claw matching with circular slab bayonet socket, and socket wrench specially adapted for it welded top has nut.
