Description
Technical field
The present invention relates to a kind of resistance test device, relate in particular to the device that a kind of male-tapered equipment casing to 35KV and following high-tension switch cabinet carries out resistance test.
Background technology
At present, to having the high-tension switch cabinet of male-tapered equipment casing, dispatching from the factory or on-the-spot when carrying out 35kV and following high pressure resistance test, because male-tapered sleeve pipe electric creep distance under air-insulated situation is short, can't realize the resistance test of standard-required, and the at present main method that connects power cable and installation code cable splice that adopts, or the external taper equipment casing of method that applies all insulation sheath outside on the taper carries out resistance test.And the main problem that adopts above-mentioned two kinds of methods to exist is: the method that adopts power cable and installation code cable splice, though process of the test can solve, but experimentation cost is very high, and the size of test site also had very high requirement, be difficult to sometimes at the scene find suitable test cable, and the installation process complexity, length consuming time, can't realize the purpose of fast detecting, and require very high, especially very obvious in product lot quantity detection test the construction technical staff of cable.Withstand voltage test belongs to destructive test, and the normal cable joint carries out just can not dropping into actual motion again after the above detection of secondary, causes adopting the method test cost of cable splice very high.Though it is simple to adopt the method for common all insulation sheath to install, with low cost, but but can only satisfy the examination requirements of 10kV and following switchgear, can not satisfy the higher trial voltage requirement of 24kV and 35kV equipment, therefore, need provide a kind of safe and reliable pick-up unit that can carry out resistance test to the male-tapered equipment casing of 35kV and following high-tension switch cabinet.
Summary of the invention
The present invention is directed to shortcoming of the prior art, provide a kind of rational in infrastructure, install reliably, easy and simple to handle, experimentation cost is cheap, can carry out the device of resistance test to the male-tapered equipment casing of 35KV and following high-tension switch cabinet.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of resistance test device of male-tapered equipment casing of high-tension switch cabinet comprises cable stress terminal, insulating boot cover and conduction fixed bar, wherein:
Described insulating boot cover is made of a main insulating layer at least, and an end processing and forming of described main insulating layer has cone-shaped interface, is used for matching with the conical surface of the male-tapered equipment casing of high-tension switch cabinet, is arranged with described cable stress terminal outside the other end.
Described main insulating layer inside is provided with stay pipe, runs through described conduction fixed bar in the described stay pipe.
One end of described conduction fixed bar is processed with the standard interface that is connected with described male-tapered equipment casing, and the other end is processed with fixed orifice and mounting hole, and the fixed pin that matches with described fixed orifice is used for that the conduction fixed bar is fixed on described insulating boot and puts.Experiment power supply is connected with an end that is processed with mounting hole, carries out resistance test then.
Described insulating boot cover also comprises external shielding layer.
Described insulating boot cover also comprises inner conducting layer.
Described insulating boot cover and described cable stress terminal can be split-type structurals.
Described insulating boot cover and described cable stress terminal also can be integral structures.
The invention has the beneficial effects as follows:
Resistance test device provided by the present invention is to be in the same place power cable and cable splice are integral prefabricated, has cancelled the use of power cable and the installation of power cable connector, and installation process is simple, and the reliability height is easy to use.Have the following advantages simultaneously:
1, can satisfy the trial voltage requirement easily: the outside surface of insulating boot cover can be covered with shield assembly, does not need to consider that sleeve pipe phase spacing and sleeve pipe to the withstand voltage required distance on housing ground, can carry out the withstand voltage test requirement to three-phase simultaneously.
2, install simply: insulating boot cover and cable stress terminal all can be prefabricated in the factory, the inner conical surface cleaning of male-tapered equipment casing that only need guarantee the inner conical surface of cone-shaped interface of insulating boot cover and high-tension switch cabinet during installation is lubricated, and make it cooperate installation, the fixed bar that will conduct electricity then passes the insulating boot cover makes the one end be connected with the male-tapered equipment casing, the other end is connected with experiment power supply, can carry out resistance test; Sheathed cable stress terminal outside insulating boot cover more can strengthen the insulating property of pick-up unit.
3, with low cost: standard cable and cable attachment moiety are installed complicated, the purchase cost height, and work progress is long, need purchase modular connection when power cable is installed, and quality is had very high requirement; After adopting such scheme, purchase cost only be the installation of cable and annex scheme 1/5th in addition still less.
