Description

A kind of fixture for vacuum circuit-breaker eedle threader
Technical field
The utility model relates to circuit breaker and manufactures field, is specifically related to a kind of fixture for vacuum circuit-breaker eedle threader.
Background technology
Circuit breaker (English name: circuit-breaker) refer to the electric current that can close, carry and cut-off under normal loop condition and can close, the switching device of carrying and the electric current under cut-offfing abnormal loop condition in official hour.
Circuit breaker can be used to distribute electric energy; infrequently start asynchronous motor; protection is carried out to power circuit and motor etc., can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for they, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And generally do not need to change parts after disjunction fault current.At present, obtain a wide range of applications.Circuit breaker is divided into primary cut-out by its scope of application, and low-voltage circuit breaker, and high-low pressure identification of boundaries is fuzzyyer, is called High-Voltage Electrical Appliances generally by more than 3kV
Vacuum circuit-breaker is a kind of primary cut-out, gains the name because the dielectric of contact gap after its arc-extinguishing medium and arc extinguishing is all high vacuum; It has volume little, lightweight, be applicable to frequent operation, advantage that arc extinguishing need not overhaul, apply comparatively universal in power distribution network.Vacuum circuit-breaker is 3 ~ 10kV; indoor distribution in 50Hz three-phase alternating current system; can in industrial and mining enterprises, power plant, transformer station as the protection of electric equipment and control; be specially adapted to the field of employment requiring non-oil ultra high vacuum system, less maintenance and frequent operation, circuit breaker is configurable in middle-placed switch cabinet, double-layer cabinet, fixing cabinet and uses as control and protection high voltage electric equipment.
Vacuum circuit-breaker is as using commonplace circuit breaker in power distribution network, and the reliability in its use is primary, and the requirement of the manufacturing is higher, needs complete monitoring, when needed, can trace back to whole assemblings and test data the very first time.
The first step of vacuum circuit-breaker final assembly (not the portion's of comprising dress) is that the cabinet of vacuum circuit-breaker (fitting operation mechanism) is placed into production line, all adopt manually to lift (weight ratio is heavier) in the past, not only require great effort, also easily collide with, also easily forget that barcode scanning is (in order to monitor and review, need to sweep bar code, in typing production system), and be not easy to control material loading rhythm.
If design a kind of automatic wire charging device, that just can address this problem substantially, but eedle threader, first need a fixture, ensure that clamping is firm, the cabinet of vacuum circuit-breaker can not be damaged.
Therefore, design a kind of fixture for vacuum circuit-breaker eedle threader, ensure that clamping is firm, can not damage the cabinet of vacuum circuit-breaker, be this area technical issues that need to address.
Utility model content
The technical problems to be solved in the utility model: design a kind of fixture for vacuum circuit-breaker eedle threader, ensures that clamping is firm, can not damage the cabinet of vacuum circuit-breaker.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
For a fixture for vacuum circuit-breaker eedle threader, comprise the header board of level, the centre of described header board is fixed with roller gear, and described roller gear can do the rotation of horizontal direction based on described header board; The below at described header board two ends is respectively equipped with clamping limb, is fixed with the tooth bar mated with described roller gear above described clamping limb; Described tooth bar is located at the both sides of described roller gear respectively, and described tooth bar can move along the length direction of described header board; Be provided with multiple alignment pin inside described clamping limb, described alignment pin matches with the cabinet of described vacuum circuit-breaker; Be provided with guide rail below described header board, described clamping limb upper end is fixed with the slide block coordinated with described guide rail; Described clamping limb inner surface is provided with an elastic damping layer.
Preferably, described alignment pin front end is truncated cone-shaped.
Preferably, the material of described alignment pin is polytetrafluoroethylene.
Preferably, described guide rail is line slideway.
Preferably, described elastic damping layer is PVC material.
Pass through technique scheme, a kind of fixture for vacuum circuit-breaker eedle threader that the utility model provides, the motion of clamping limb is driven by the principle of rack-and-pinion, and be provided with guide rail and slide block, such energy ensures steady clamping vacuum circuit-breaker at the uniform velocity, and inside clamping limb, being provided with alignment pin and elastic damping layer, chucking power is firm, can not damage the cabinet of vacuum circuit-breaker.Its beneficial effect is: ensure that clamping is firm, can not damage the cabinet of vacuum circuit-breaker.
