Description
Technical field
This utility model relates to the Partial discharge detector of insulated metal closed switch equipment, particularly one and is used for
The bonder probe clamping device of Partial discharge detector.
Background technology
In the Cubicle Gas-Insulated Switchgear of power equipment, discharging in only subregion, and does not extends through
Executing between alive conductor, the most not yet puncture, this phenomenon is referred to as shelf depreciation, and it is due to internal field's distortion, office
Portion's field intensity is concentrated, thus causes the gas discharge in dielectric subrange or puncture.It is likely to occur on conductor limit, also
Being likely to occur in surface or the inside of insulator, the shelf depreciation in Cubicle Gas-Insulated Switchgear even can be corroded
Insulant, and finally result in insulation breakdown.Therefore, carry out Partial Discharge Detection, the generation of prevention discharge accident, maintenance is set
Standby safety and power system stability are run highly important meaning.
Shelf depreciation is a kind of pulsed discharge, and it can produce in Cubicle Gas-Insulated Switchgear inside and around space
Physical phenomenon and the chemical changes such as raw a series of light, sound, vibration electrically and mechanically, these produce with shelf depreciation
Various physical and chemical changes can be that monitoring power equipment built-in electrical insulation state provides detection signal.
Partial Discharge Detection contributes to finding the multiple insulation defect within Cubicle Gas-Insulated Switchgear, is to examine
The important means of disconnected Cubicle Gas-Insulated Switchgear health status.Partial Discharge Detection actually used in, need
Persistently observing the detection collection of illustrative plates of Partial discharge detector to waveform of pinpointing the problems, this just requires the bonder of Partial discharge detector
Probe must closely, stably be fitted with Cubicle Gas-Insulated Switchgear and continue for some time.At present, shelf depreciation inspection
The mounting means of the bonder probe surveying instrument is: uses rubber band to be popped one's head in by the bonder of Partial discharge detector and is bundled in gas
On insulated metal closed switch equipment, the bonder probe of this installation French easily slides, and is difficult to gas-insulated metal-enclosed
Switchgear fits tightly, and certainty of measurement is inaccurate, needs measurement is repeated several times, and considerably increases the measurement time.
Summary of the invention
This utility model is to solve above-mentioned technical problem, it is provided that a kind of can be by the bonder in Partial discharge detector
Probe fits tightly with Cubicle Gas-Insulated Switchgear, improves certainty of measurement, reduces repeated measure number of times, is greatly shortened
The bonder probe clamping device for Partial discharge detector of measurement time.
Technical solution of the present utility model is:
A kind of bonder probe clamping device for Partial discharge detector, it is characterized in that and includes back-off cloth
The trapezoidal housing put, is provided with wire perforation at trapezoidal housing end face, and in trapezoidal housing left and right, endplate root is respectively equipped with bent outward
The outer of folding shape, and on two outers, it is respectively equipped with two cord hole, each cord hole is each passed through stay cord, and at each stay cord
Bottom arranges set foot, installs only line pressing plate by screw on the end plate of trapezoidal housing left and right, and each stay cord is from bottom to top through correspondence
Only pass between line pressing plate and trapezoidal cabinet；The quadrangle box that back-off is arranged is set in trapezoidal housing, and on trapezoidal housing top
Between face and quadrangle box end face, compression spring is set.
The beneficial effects of the utility model are:
1, owing to being provided with the quadrangle box that back-off is arranged in trapezoidal housing, and at trapezoidal housing end face and quadrangle box
Arranging compression spring between end face, trapezoidal housing is buckled at Cubicle Gas-Insulated Switchgear detection mouth, in compression spring
Elastic force effect under, the bonder of the Partial discharge detector being placed in quadrangle box probe and gas-insulated metal enclosed switchgear
Equipment fits tightly, and improves certainty of measurement, decreases repeated measure number of times, substantially reduces the measurement time.
2, owing to being respectively equipped with two cord hole on the outer of trapezoidal housing left and right endplate root, wear respectively in each cord hole
Cross bottom and set foot stay cord is set, trapezoidal housing left and right end plate installs only line pressing plate, each stay cord warp from bottom to top by screw
Corresponding only passes between line pressing plate and trapezoidal cabinet, and the set foot of each stay cord bottom is respectively fitted over gas-insulated metal-enclosed opening
Pass equipment on hook architecturally, while straining each stay cord, and firmly under press on trapezoidal housing, then locking only line pressing plate
Screw, prevent the de-pine of trapezoidal housing, it is ensured that bonder probe fits tightly with Cubicle Gas-Insulated Switchgear.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is trapezoidal housing and the location diagram of quadrangle box in Fig. 1；
In figure: the trapezoidal housing of 1-, 2-wire is bored a hole, and 3-outer, 4-cord hole, 5-stay cord, 6-overlaps foot, and 7-stops line pressing plate, 8-
Quadrangle box, 9-compression spring.
Detailed description of the invention
The clamping device as it can be seen, a kind of bonder for Partial discharge detector is popped one's head in, the ladder arranged including back-off
Shape housing 1, is provided with wire perforation 2 at trapezoidal housing 1 end face, is respectively equipped with outwards bending at trapezoidal housing about 1 endplate root
The outer 3 of shape, and on two outers 3, it is respectively equipped with two cord hole 4, each cord hole 4 is each passed through stay cord 5, and is respectively drawing
The bottom tying-up set foot 6 of rope 5, installs only line pressing plate 7 by screw on trapezoidal housing about 1 end plate, and each stay cord 5 is from bottom to top
Only pass between line pressing plate 7 and trapezoidal cabinet through corresponding；Arrange in trapezoidal housing 1 back-off arrange quadrangle box 8, and
Trapezoidal housing 1 end face is connected compression spring 9 between quadrangle box 8 end face.
During operation, first the bonder of Partial discharge detector is popped one's head in and be placed in quadrangle box 8, and bonder is popped one's head in
Wire bored a hole by the wire on trapezoidal housing 1 end face and 2 pass, then trapezoidal housing 1 is buckled in gas-insulated metal-enclosed opening
Closing at equipment Inspection mouth, the bonder probe in quadrangle box 8 abuts on GIS, is overlapped respectively by the set foot 6 of each stay cord 5 bottom
At Cubicle Gas-Insulated Switchgear on hook architecturally, while straining each stay cord 5, and firmly under press trapezoidal
Housing 1, makes the probe of the bonder in quadrangle box 8 closely be pressed against on Cubicle Gas-Insulated Switchgear, then locking is only
Screw on line pressing plate 7, makes only line pressing plate 7 be fastened by corresponding anchor clamp, the wire access office finally popped one's head in by bonder
Portion's discharge detector, starts Partial Discharge Detection.
