Description
Technical field
The utility model relates to a kind of instrument transformer secondary winding junction box.
Background technology
In order to guarantee the power system security economical operation, must carry out monitoring and measuring to the ruuning situation of power equipment.But general measurement and protective device can not directly access high-tension apparatus No. one time, and the high voltage of primary system need to be become low-voltage and little electric current with large electric current scaling transformation, supply with measuring instrument and protective device and use.Carry out the equipment of these transformation task, modal is exactly instrument transformer.To regularly test the instrument transformer secondary coil according to relevant regulations.At present, there is following problem in traditional test method:
1, the binding post of 10kV instrument transformer secondary side is than comparatively dense, if use clip in process of the test, owing to the space reason, maybe can cause two clip contacts, cause test failure, because wiring causes error, reexamining also, the wiring meeting causes a large amount of time wastes in the practice process.Because the 10kV instrument transformer has three secondary winding, so when it is carried out insulation resistance test, need to change frequently wiring, extremely loses time.The staff needs to get into the cupboard back after whenever making an instrument transformer, carries out thread-changing, discharge, and frequent operation has brought a lot of inconvenience to the staff, and is tired easily.
2, because the above instrument transformer of electric pressure 110kV substantially all is installed in the above height of 2m, the staff is when carrying out insulation measurement and winding D.C. resistance test change wiring, all need work high above the ground, according to relevant regulations, during work high above the ground, must wear safety belt, and there is the guardian to guard, so not only strengthened staff's work difficulty, and waste of manpower, and have very large potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of instrument transformer secondary winding junction box, to overcome present prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of instrument transformer secondary winding junction box comprises container body of outer cover, and a side is provided with terminal block in the described container body of outer cover, evenly be penetrated with several binding posts on the described terminal block, described binding post is equipped with lead-out wire, and lead-out wire is fixed on the terminal block by pressing plate, and lead-out wire one end is connected with binding clip.
Preferably, described binding post has five groups ten, and every winding terminal equidistantly is arranged on the terminal block at a distance of 60mm.
Further, every winding terminal right side is respectively equipped with port label on the described terminal block.
Further, described terminal block is fixed on the container body of outer cover by set bolt and terminal bracket.Described binding clip is the metal clip that is surrounded by insulating barrier.
1), solved the instrument transformer insulation resistance test the beneficial effects of the utility model are:, the problem of work high above the ground and inside switch cabinet operation has not only been saved the time of test change wiring, and has been improved the security reliability of test.2), reduced testing crew and climb, enter in the switch cubicle, the frequent test connection has not only reduced the labour intensity of testing crew, and has greatly improved experimental safe reliability and precision.3), cost is low, can be widely used in the work that electric power, power plant etc. relate to 10kV ~ 220kV instrument transformer secondary winding insulation resistance test.4), applicability is strong, light and flexible can be used as auxiliary and instrument transformer secondary resistance D.C. resistance testing apparatus coupling and uses.
