Background technology
In a single day heating appears in routine SF6 (2000A) primary cut-out switch contact in the high-voltage switch contact, its contact, over-heated fault might occur melting, and this will cause main-transformer jumping electricity, causes the damage of production equipment to reach environment damage.Contact pile crown in this kind switch increases contact resistance because the not enough regular meeting of pressing force of the spring causes the contact loose contact, causes the contact heating, causes the holddown spring catastrophic failure, thereby causes arcing between contact and copper bar, finally causes contact burning.
This SF6 (2000A) killer switch can't the detector switch static contact in conventional test and moving contact between the contact resistance and the contact condition of 3 set of contact pile crowns whether synchronous.So the contact condition of switch movable contact and the snap-in force of spring are lacked inspection, test and maintenance for a long time, thereby cause above-mentioned catastrophic failure.
The utility model content
The purpose of this utility model is in order to solve the problem that prior art exists, provide a kind of high-voltage switch contact state detector that can detect, to avoid the fault of high-voltage switch contact heating, scaling loss to the snap-in force of the contact condition of switch static contact and moving contact and spring.
The purpose of this utility model is achieved through the following technical solutions:
A kind of high-voltage switch contact state detector is used for analog detection and places the moving contact on the high-voltage switch gear dolly and place contact resistance between the static contact of high-voltage board, and it comprises:
Detect vehicle frame, structure is: car bottom plate; The bottom surface of car bottom plate is equipped with 4 wheels; Fix a machine plate vertical with car bottom plate above the car bottom plate, the both sides of machine plate are installed a handle respectively;
Several detection contact, adopting bolt, reed and pad to distribute respectively is installed on the described machine plate, the quantity and the position of moving contact are identical on the position of its quantity and distribution and the described high-voltage switch gear dolly, its shape, size and mutual distance are consistent with the static contact of described high-voltage board, form one group of simulation static contact of simulating described high-voltage board static contact.
In described 4 wheels, 2 is universal pulley, and 2 is directed pulley.

The beneficial effects of the utility model:
Detecting device of the present utility model can be measured the static contact of SF6 (2000A) primary cut-out switch and the contact resistance between the moving contact, pressing force of the spring, contact synchronism easily, by detecting the contact state that effectively to hold high-voltage switch gear, in time remove a hidden danger, avoid the generation of high-voltage switch contact heating, over-heated fault.The utility model is applicable to the power supply place of various primary cut-out switch operations.
For further specifying above-mentioned purpose of the present utility model, design feature and effect, the utility model is elaborated below with reference to accompanying drawing.
Description of drawings
Fig. 1 is the structural representation of this detecting device;
Fig. 2 is the left view of Fig. 1.
Embodiment
Accompanying drawing below in conjunction with embodiment is elaborated to embodiment of the present utility model.
Referring to Fig. 1-Fig. 2, high-voltage switch contact state detector of the present utility model is used for analog detection and places the moving contact on the high-voltage switch gear dolly and place contact resistance between the static contact of high-voltage board, and its structure comprises referring to Fig. 1:
Detect vehicle frame 10, comprise: car bottom plate 8; The bottom surface of car bottom plate 8 utilizes bolt 1, reed 2 and pad 3 that 4 wheels 13 (present embodiment adopts 2 universal pulleys, 2 directed pulleys) are installed; A machine plate 2 vertical with car bottom plate 8 is fixed in the top welding of car bottom plate 8, and the both sides of machine plate 2 are installed a handle 14 respectively as cart handle.The overall height that detects vehicle frame 10 is consistent with the overall height of described high-voltage switch gear dolly.
Several detection contact 7 (adopt 12 detection contact in the present embodiment accompanying drawing, wherein every neighbouring two contacts are a contact), adopt bolt 4, reed 5 and pad 6 to distribute respectively and be installed on the machine plate 2, the quantity and the position of the moving contact on the position of its quantity and distribution and the described high-voltage switch gear dolly are identical.Referring to Fig. 3, the shape of each detection contact and size are consistent with the static contact of described high-voltage board, and mutual is consistent apart from the size also spacing with each static contact of high-voltage board, form one group of simulation static contact.Each detection contact be the contact of two trapezoidal tip foremost, guarantee to guarantee that contact is good between contact in the moving contact that is deep into the high-voltage switch gear dolly that this detection contact can be good.Because the height of above-mentioned inspection vehicle is identical with the high-voltage switch gear dolly, thus guarantee on the inspection vehicle one group simulate static contact can with one group of moving contact intact linking on the high-voltage switch gear dolly.
In the present embodiment, be reinforcing machine plate 2,, weld two gusset plates 15 in machine plate 2 these one sides of back of the body detection contact 7.
During detection, earlier the high-voltage switch gear dolly is pulled out from high-voltage board, and carry out suitable fixing.Then detecting device of the present utility model is aimed at the switch dolly and directly be connected (the simulation static contact of being made up of 12 detection contact 7 is connected with one group of moving contact on the switch dolly), the simulated high-pressure switch is in the running status position.Measure the resistance between dynamic/static contact at this moment with electric bridge or high precision multimeter again, amount to the contact resistance value of 12 detection contact.By contrasting this 12 resistance values, can judge whether the contact condition between the high-voltage switch gear moving contact is synchronous.Again by historical data contrast (historical trend) and homogeneous data contrast, grasp the variation tendency of resistance value, thereby hold the snap-in force of moving contact contact condition and spring indirectly, significantly rise or difference, then need to carry out more deep detection and maintenance if certain data has.
