Description
technical field
The utility model relates to a kind of extending formula switchgear Insulation monitoring novel sensor, belongs to the inner local discharge signal detection technique field of switchgear.
background technology
The uhf sensor of the portable detection of conventional on-site is hand-held, and testing staff needs to hold sensor and presses close on the shell of equipment to be detected.Under this detection mode, the health of testing staff likely directly touches equipment itself, there is certain potential safety hazard; And when detecting between sensor and detecting instrument position may be separated by very far away, need multiple operating personnel's collaborative work, add maintenance workload.
In the detection method of the inner local discharge signal of current switchgear, ultrahigh frequency method and ultrasound wave realize the practical feasible method of switchgear partial discharge monitoring at present.The monitoring range of ultrahigh frequency method is wider, and during on-line monitoring, number of sensors is less, and shelf depreciation on-line checkingi is quick and convenient with location.Ultrahigh frequency method has irreplaceable advantage due to it in switchgear partial discharge monitoring, has become the Main Means that switchgear runs on-the-spot Partial Discharge Detection in recent years.And supercritical ultrasonics technology, due to hyperacoustic very fast in switchgear decay, therefore more easily carry out defect location.
summary of the invention
The purpose of this utility model is, according to the safety problem that con-ventional handheld uhf sensor in use exists, the utility model proposes a kind of extending formula switchgear Insulation monitoring novel sensor, with the safety risks avoiding con-ventional handheld uhf sensor to exist.
The technical solution of the utility model is, a kind of extending formula switchgear Insulation monitoring novel sensor of the utility model is made up of uhf sensor antenna, ultrasonic sensor, sensor outer housing, sensor base, ultra-high frequency signal line, ultrasonic signal line and insulating bar.Uhf sensor antenna and ultrasonic sensor embed or insulate integral cast in sensor outer housing; Sensor outer housing is arranged in sensor base; Insulating bar is threadedly fixed on the sensor base back side; Ultrasonic signal line one end connects ultrasonic sensor, and the other end connects first interface bottom insulating bar through sensor base; Ultra-high frequency signal line one end connects uhf sensor antenna, and the other end connects the second interface bottom insulating bar through sensor base.
Ultra-high frequency antenna of the present utility model is flat plane antenna or three-dimensional antenna, can be circular, also can be rectangle, also can be erose.
Insulating bar one end of the present utility model is provided with coaxial connector, can be connected with separately adding rod member, increases the use length of insulating bar.
The beneficial effects of the utility model are, a kind of extending formula switchgear Insulation monitoring novel sensor of the utility model have employed insulating bar supporting construction, sensor is extended on also near high-tension apparatus by insulating bar and detects.The utility model can carry out insulation integral cast to sensor entirety, improves integral insulation level and the sealing property of sensor.

The ultra-high frequency antenna of the present embodiment, is embedded in sensor outer housing by the mode of building, for the ultra-high frequency signal produced during detector switch apparatus local discharge;
The ultrasonic sensor of the present embodiment, is embedded in sensor outer housing by the mode of building, and puts the ultrasonic signal of phenomenon generation for detector switch equipment office;
The sensor outer housing of the present embodiment, uses aluminium shell metalworking mode to make, ultra-high frequency antenna and ultrasonic sensor is built in this shell;
The sensor base of the present embodiment, plays the bindiny mechanism's effect in the middle of sensor outer housing and insulating bar;
The insulating bar of the present embodiment, is fixed on the sensor base back side, the hand-held insulating bar of operating personnel, can allow sensor near high-tension apparatus, avoids people to contact and close high-tension apparatus; Insulating bar one end is provided with coaxial connector, can be connected with separately adding rod member, increases the use length of insulating bar.
Signal wire comprises ultra-high frequency signal line 4 and ultrasonic signal line 5, outputs to the interface bottom insulating bar from sensor signal, plays signal connection function;
Signal output bottom insulating bar comprises first interface and the second interface, is externally exported by two BNC connector modes, and wherein first interface connects ultrasonic signal line 3, second interface and connects ultra-high frequency signal line 4.
A kind of extending formula switchgear Insulation monitoring novel sensor assembling process of the present embodiment:
Assemble according to Fig. 1, wherein uhf sensor antenna 2, ultrasonic sensor 1, ultra-high frequency signal line 4 and ultrasonic signal line 5 can fix placement orientation by the mode such as gluing in advance.Assemble the casting of laggard line sensor integral insulation.Insulating bar 6 is threadedly fixed on sensor base 3 back side, and ultra-high frequency signal line 4 and ultrasonic signal line 5 are drawn by insulating bar 6 inside, and are welded on the BNC connector of output.
When testing from signal extension line output port measuring-signal, gathering superelevation and keeping pouring in the signal that in the switchgear of antenna and ultrasonic equipment detection, shelf depreciation produces.
