Abstract
The invention discloses a switch cabinet capable of detecting flashover. The switch cabinet capable of detecting the flashover comprises a switch cabinet body, wherein a flashover photoelectric sensor, a flashover position sensor, an ozone sensor and a plurality of cameras are arranged inside the switch cabinet body, and the cameras are connected with a monitor. The flashover photoelectric sensor is capable of detecting lightning flash or sparks when flashover occurs, the flashover position sensor is capable of positioning the position where the flashover occurs, and the ozone sensor is capable of detecting the content of ozone in the switch cabinet body. By means of the structure, when the flashover occurs, the flashover photoelectric sensor can timely detect the lightning flash or the sparks and sends the signals to a controller. Meanwhile, the flashover position sensor can position the lightning flash or the sparks and sends the signals to the controller. Therefore, a detection worker can arrange a maintenance worker to timely replace an insulating part in the position according to the received flashover and position signals when overhauling the switch cabinet, overhaul is more convenient and rapid, and the switch cabinet is safer and more reliable to operate.
Description
Technical field
The present invention relates to a kind of power switch cabinet, particularly a kind of switch cubicle that can detect flashover.
Background technology
Major loop instantaneous overvoltage in the switch cubicle as switching overvoltage etc., with can not making in the cabinet insulation breakdown, but may make the weak place of insulation in the cabinet flashover occur, and after the flashover, major loop is still continuing operation.Do not destroy fully though the insulation of flashover point occurs, damage, become accident potential, in time change when needing again the switch cubicle maintenance.Existing method can detect instantaneous overvoltage, but can not detect flashover, and flashover appears at that position of switch cubicle, brings difficulty to maintenance, as overhauls not exclusively, then buries accident potential.
Summary of the invention
The technical problem to be solved in the present invention provides and a kind ofly can detect the switch cubicle that flashover and flashover occurrence positions, maintenance can detect flashover easily.
For solving the problems of the technologies described above, technical scheme provided by the invention is as follows:
A kind of switch cubicle that can detect flashover comprises the switch cubicle body, is provided with the flashover electro-optical pickoff in the described switch cubicle body, lighting or spark when this flashover electro-optical pickoff can detect the flashover generation.
Also be provided with the flashover position transducer in the described switch cubicle body, this flashover position transducer can position the position that flashover takes place.
Also be provided with ozone sensor in the described switch cubicle body, but the content of ozone in this ozone sensor sense switch cabinet body.
Also be provided with several cameras in the described switch cubicle body, this camera is connected with monitor.
The present invention is owing to adopted said structure, and when flashover took place, the flashover electro-optical pickoff can in time detect lighting or spark, and signal is passed to controller; Simultaneously, the flashover position transducer can position the position of lighting or spark, after position signalling is passed to controller, the testing staff can be by flashover and the position signalling that receives, when switch cubicle overhauls, arrange the maintainer in time the insulating part of this position to be changed, overhaul more conveniently, quick, the operation of switch cubicle is also safer, reliable.
Description of drawings
Fig. 1 can detect the structural representation of the switch cubicle of flashover for the present invention.
Wherein have: 1. switch cubicle body; 2. flashover electro-optical pickoff; 3. flashover position transducer; 4. ozone sensor; 5. camera; 6. monitor.
Embodiment
The present invention is further detailed explanation below in conjunction with embodiment.
A kind of switch cubicle that can detect flashover comprises switch cubicle body 1, is provided with flashover electro-optical pickoff 2, flashover position transducer 3 in this switch cubicle body 1.
Lighting or spark when flashover electro-optical pickoff 2 can detect the flashover generation, flashover position transducer 3 can position the position that flashover takes place.When flashover took place, flashover electro-optical pickoff 2 can in time detect lighting or spark, and signal is passed to controller; Simultaneously, flashover position transducer 3 can position the position of lighting or spark, after position signalling is passed to controller, the testing staff can be by flashover and the position signalling that receives, when switch cubicle overhauls, arrange the maintainer in time the insulating part of this position to be changed, overhaul more conveniently, quick, the operation of switch cubicle is also safer, reliable.
In addition, also be provided with ozone sensor 4 in this switch cubicle body 1, but the content of ozone in these ozone sensor 4 sense switch cabinet bodies.When flashover or corona take place, can produce ozone, the content by monitoring switch cubicle ozone can further monitor flashover, comprises corona, and signal is passed to controller that make insulating part can in time be overhauled, change, the insulation of insulating part is safer, reliable.
Further, also be provided with several cameras 5 in the switch cubicle body 1, this camera 5 is connected with monitor 6.The user can be as required arranges the quantity of camera 5 at four jiaos of switch cubicle body 1 or the position that needs emphasis to monitor, operation to switch cubicle inside is monitored, when flashover takes place, this section video can be preserved, so as vivider, understand flashover intuitively, and carry out that problem is searched and the analysis of causes.
