Abstract
The utility model discloses a butt -joint structural for ac voltage withstand test test device, ac voltage withstand test test device include testing transformer and current -limiting resistor, the current -limiting resistor tip have the butt joint guide arm that is used for the butt joint, this butt -joint structural includes splicing, be connected and be unsettled splicing and testing transformer, to there being the butt joint hole that is used for the butt joint in the splicing, current -limiting resistor's butt joint guide arm pass the butt joint hole and dock splicing. The butt joint hole is waist shape hole. The butt joint piece passes through the fix with screw on testing transformer. The structure in waist shape hole is big -end -up, moves on to at the lower part office in waist shape hole under the top of current -limiting resistor through waist shape hole to reach the butt joint position. The utility model discloses simple structure, it is convenient to implement, docks effectually.
Description
Technical field
The utility model relates to a kind of docking structure, in particular to the docking structure of a kind of alternating-current voltage resistance test device.
Background technology
Power equipment is in operation, and the effect that insulation subjects electric field, temperature and mechanical vibration for a long time can deteriorate gradually, forms defect. 500kV transformer power frequency pressure-resistant apparatus is wherein a kind of ac voltage withstanding device, and industrial frequency AC withstand voltage test is the qualification insulation of electrical installation the most direct method of intensity. 500kV industrial frequency AC pressure-resistant apparatus comprises 500Kv and tests the parts such as transformer, current limliting resistance, capacity divider, one end of current limliting resistance have for dock to guide rod. When ac voltage withstanding testing installation is tested, the current limliting resistance of this testing installation and test transformer need to dock, traditional docking mode is that current limliting resistance is directly slowly pushed to test transformer, being docked with test transformer by guide rod by current limliting resistance, docks current limliting resistance and the collision testing transformer when docking inaccurate and docking that cause like this and all can have influence on the reliability of this ac voltage withstanding testing installation.
Practical novel content
Shortcoming that when the utility model solves current limliting resistance in existing ac voltage withstanding experimental installation and test transformer docks, docking effect is not good and can increase current limliting resistance to the stability after guide rod and butt strip docking.
In order to achieve the above object, the utility model provides a kind of docking structure for alternating-current voltage resistance test device, this alternating-current voltage resistance test device comprises test transformer and current limliting resistance, described current limliting resistance end useful in docking to guide rod, this docking structure comprises butt strip, described butt strip is connected and unsettled with test transformer, and described butt strip has the butt hole for docking, guide rod is passed butt hole the docking with butt strip of described current limliting resistance.
Preferably butt strip is connected by screw mode is connected with test transformer.
Preferably described butt strip material is iron, copper or aluminium.
When described current limliting resistance slowly dock with test transformer, current limliting resistance to guide rod first through butt strip, current limliting resistance to guide rod by after butt hole slowly and test transformer complete to dock.
Preferably described butt hole is vertical waist shaped hole.
Preferably described waist shaped hole is the structure under upper size.
When equipment docks, current limliting resistance guide rod is first slowly entered from the upper circular arc of butt hole, then after slowly reaching the degree of depth of docking, current limliting resistance moves down, the lower portion that guide rod is in butt hole of current limliting resistance, the diameter of guide rod is slightly less than the aperture of waist shaped hole lower part, then the aperture of guide rod with the lower part of waist shaped hole is agreed with mutually, thus complete docking. Simultaneously due to the up big and down small structure of waist shaped hole, when being stuck in lower part circular arc when guide rod is moved to less lower part of current limliting resistance, reach fixing object.
The utility model structure is simple, economic and practical, and docking effect is accurate, reliably.
Accompanying drawing explanation
The structure iron of Fig. 1 a kind of docking structure for alternating-current voltage resistance test device described in the utility model.
In figure, Reference numeral is respectively: 1. butt strip; 2. butt hole
Embodiment
As shown in Figure 1, on the utility model test transformer in the prior art, a connection butt strip 1 and butt strip 1 are unsettled, described butt strip 1 has a butt hole 2 for docking, described butt hole 2 with current limliting resistance guide rod is corresponding when docking. Compare current limliting resistance and test transformer and directly dock, dock better effects if by butt strip, more accurately.
Preferably butt strip 1 is connected by screw mode is connected with test transformer. It is convenient to handling at any time and changes butt strip.
Preferably described butt strip 1 material is iron, copper or aluminium. Adopt metallic substance iron copper aluminium can reach hardness requirement, it is achieved docking, also can realize current limliting resistance and the effect of test transformer channels, thus form complete experimental installation.
When described current limliting resistance slowly dock with test transformer, current limliting resistance to guide rod first through butt strip 1, current limliting resistance to guide rod by after butt hole 2 slowly and test transformer complete to dock.
Preferably described butt hole 2 is vertical waist shaped hole. Butt strip 1 is connected with test transformer by screw. Screw connects is convenient to change at any time butt strip 1, is convenient to dismounting.
The structure of preferably described waist shaped hole is up big and down small. First being entered by the upper part of waist shaped hole by guide rod of current limliting resistance, then moves up into lower part down, reaches docking location. Up big and down small structure be convenient to docking, and move to from above the less lower part in aperture can set current limiting resistance to guide rod.
Above in conjunction with accompanying drawing, the utility model is exemplarily described; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that technical solutions of the utility model carry out; or without improving, technical solutions of the utility model are directly applied to other occasion, all within protection domain of the present utility model.
