Description

Coupler Probe Holder Tool for Partial Discharge Detectors

technical field

The utility model relates to a partial discharge detector used for insulating metal-enclosed switchgear, in particular to a coupler probe clamping tool used for the partial discharge detector.

Background technique

In the gas-insulated metal-enclosed switchgear of power equipment, only a part of the area discharges, but does not penetrate between the conductors to which the voltage is applied, that is, it has not yet broken down. This phenomenon is called partial discharge. It is due to local electric field distortion, local field Strong concentration, resulting in gas discharge or breakdown in the local area of the insulating medium. It may occur on the side of the conductor, or on the surface or inside of the insulator. The partial discharge in the gas-insulated metal-enclosed switchgear may even corrode the insulating material, and finally lead to insulation breakdown. Therefore, it is of great significance to carry out partial discharge detection and prevent the occurrence of discharge accidents to maintain the safety of equipment and the stable operation of power systems.

Partial discharge is a kind of pulse discharge, which will produce a series of physical phenomena and chemical changes such as light, sound, electrical and mechanical vibration inside and around the gas-insulated metal-enclosed switchgear. Physical and chemical changes can provide detection signals for monitoring the internal insulation status of power equipment.

Partial discharge detection is helpful to discover various insulation defects inside gas-insulated metal-enclosed switchgear, and is an important means to diagnose the health status of gas-insulated metal-enclosed switchgear. In the actual use of partial discharge detection, it is necessary to continuously observe the detection spectrum of the partial discharge detector to find the problem waveform, which requires that the coupler probe of the partial discharge detector and the gas-insulated metal-enclosed switchgear must be tightly and stably attached and last for a period of time. time. At present, the installation method of the coupler probe of the partial discharge detector is: use a rubber band to bind the coupler probe of the partial discharge detector to the gas-insulated metal-enclosed switchgear. The coupler probe of this installation method is easy to slide and difficult It fits closely with the gas-insulated metal-enclosed switchgear, the measurement accuracy is not accurate, and repeated measurements are required, which greatly increases the measurement time.

Contents of the invention

The utility model aims to solve the above technical problems, and provides a device that can closely fit the coupler probe on the partial discharge detector with the gas-insulated metal-enclosed switchgear, improve the measurement accuracy, reduce the number of repeated measurements, and greatly shorten the measurement time. Coupler probe holder for partial discharge detectors.

The technical solution of the utility model is:

A coupler probe clamping tool for a partial discharge detector, which is special in that it includes a trapezoidal shell with an undercut arrangement, and a wire perforation is provided on the top surface of the trapezoidal shell, and at the bottom of the left and right end plates of the trapezoidal shell Outer edges that are bent outwards are respectively provided, and two rope holes are respectively provided on the two outer edges, and stay ropes are respectively passed through each rope hole, and a set foot is set at the bottom end of each stay rope, Screws are installed on the left and right end plates of the trapezoidal shell, and each pull cord passes between the corresponding thread-stopping plate and the trapezoidal box body from bottom to top; a square box arranged upside down is arranged in the trapezoidal shell, and A compression spring is arranged between the top surface of the trapezoidal housing and the top surface of the square box body.

The beneficial effects of the utility model are:

1. Since the trapezoidal housing is provided with a square box with an upside-down arrangement, and a compression spring is provided between the top surface of the trapezoidal housing and the top surface of the square box, the trapezoidal housing is buckled at the detection port of the gas-insulated metal-enclosed switchgear , under the elastic force of the compression spring, the coupler probe of the partial discharge detector placed in the square box fits closely with the gas-insulated metal-enclosed switchgear, which improves the measurement accuracy, reduces the number of repeated measurements, and greatly shortens the measurement time. time.

2. Since there are two rope holes on the outer edge of the bottom of the left and right end plates of the trapezoidal shell, set the drawstrings through the bottom of each rope hole, and install them on the left and right end plates of the trapezoidal shell with screws. Line stop pressing plate, each pull rope passes from bottom to top between the corresponding line stop pressing plate and the trapezoidal box body, and the sleeve feet at the bottom of each pull rope are respectively placed on the hooks on the structure of the gas-insulated metal-enclosed switchgear, and pulled While tightening the pull ropes, forcefully press down on the trapezoidal housing, and then lock the screws on the stop line pressing plate to prevent the trapezoidal housing from loosening and ensure the tight fit between the coupler probe and the gas-insulated metal-enclosed switchgear.
