Description
Technical field
The utility model relates to a kind of sensor for detection of the partial discharge of switchgear signal, relate in particular to a kind of integral sensor for the partial discharge of switchgear detection, ground electric wave signal and the ultrasonic signal of the generation of detector switch cabinet shelf depreciation belong to the detection technique field simultaneously.
Background technology
Switch cubicle is visual plant commonly used in the electric system, when existing insulation defect, inside switch cabinet can produce shelf depreciation, by can effectively judge the state of insulation of switchgear to the detection of shelf depreciation, it is significant to the safe and stable operation of guaranteeing switch cubicle effectively to detect shelf depreciation.
At present in the detection method of inside switch cabinet local discharge signal, ground electric wave method and supercritical ultrasonics technology be realize at present that partial discharge of switchgear detects and monitoring rate than the method for practical.The kind of inside switch cabinet shelf depreciation mainly is divided into two kinds of internal discharge and surface-discharges.The internal discharge of switch cubicle can make the land used radio wave sensor detect; The surface-discharge of switch cubicle makes the land used radio wave sensor detect DeGrain, and ultrasonic sensor can be good at addressing this problem.And for some discharges, we can detect ground electric wave signal and ultrasonic signal simultaneously, we can only detect a kind of in two kinds of signals other discharge scenario, therefore in actual use, we should complement one another with these two kinds of detection modes, can better detect all shelf depreciation situations.
In recent years, ground electric wave method and supercritical ultrasonics technology associated detection technique have become the Main Means that switch cubicle moves on-the-spot Partial Discharge Detection.But the sensor that traditional local discharge detection device adopts is single ground radio wave sensor or single ultrasonic sensor or the dual sensor that can not detect simultaneously, the testing staff need at first use a kind of detection mode that the shelf depreciation of switch cubicle is put into row and detect, and then uses another kind of instrument or switches under another detecting pattern and detect.This detection mode wastes time and energy, and has increased labour intensity.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art and a kind of integral sensor that detects for partial discharge of switchgear is provided, simultaneously the ground electric wave signal and the ultrasonic signal that produce of detector switch cabinet shelf depreciation.

Capacity coupler 1 is fixed on the inboard of the front panel 51 of housing 5, the ground electric wave signal that produces during for detection of partial discharge of switchgear.
Two signal extension lines 3 twist together, and an end of two signal extension lines 3 links to each other with ultrasound acquisition device 2 with capacity coupler 1 respectively, and the other end of two signal extension lines 3 all links to each other with signal output port 4; Signal output port 4 is installed in the housing 5.
Further, capacity coupler 1 is metal material.
Further, the shape of capacity coupler 1 can be selected square, rectangle or circle.
Again further, ultrasound acquisition device 2 is metal material.
Integral sensor of the present utility model links to each other with the Partial discharge detector device by signal output port 4.In use, the ultrasonic signal that detects of the ground electric wave signal that detects of capacity coupler 1 and ultrasound acquisition device 2 is transferred to signal output port 4 by signal extension line 3.Ground electric wave signal and ultrasonic signal that Partial discharge detector's device produces during from signal output port 4 measuring switch cabinet shelf depreciation, detect when realizing ground electric wave signal and ultrasonic signal, two kinds of detection techniques of electric wave method and supercritical ultrasonics technology jointly can be judged the state of insulation of switchgear effectively.
In sum, ground of the present utility model electric wave and ultrasound wave integral sensor, ground electric wave signal and the ultrasonic signal of the generation of detector switch cabinet shelf depreciation are avoided the large shortcoming of traditional detection mode workload simultaneously, save detection time, increase work efficiency.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
