Description
Technical field
The invention belongs to electrical equipment on-line checking fields, and in particular to a kind of circuit breaker arc bat based on vibration triggering
Take the photograph system.
Background technique
High-voltage circuitbreaker is one of important equipment of electric system, carries the tasks such as transmission and the control of electric power, peace
Row for the national games is extremely important.Therefore, the expense for how avoiding accidental power failure, shortening power off time to the maximum extent, reducing plant maintenance
With, service life for extending equipment, realize that equipment maximally utilizes, it has also become power industry current important topic.
The repair based on condition of component of high-voltage circuitbreaker generally comprises three state-detection, status assessment and maintenance decision links,
Middle state-detection and status assessment are the bases of maintenance decision.Breaker can generate switching arc in divide-shut brake, then excite
It electromagnetic wave and propagates around out.Wherein information rich in electromagnetic wave signal, these information can effectively reflect disconnected
The operation conditions of road device.Since the actuation time of breaker is very of short duration, visually it is difficult to observe electric arc within this of short duration time
From the complete procedure generated to extinguishing, therefore, existing test method is usually to be shot by manual manipulation computer to catch
Catch whole process of the breaker from electric arc generation to extinguishing in this way, shooting time point is difficult to hold, and easily misses electric arc, and
And manual operation computer shooting has certain risk for operator.Therefore, it operates inconvenient, effect is not yet
It is fully up to expectations, it limits and uses and promote.
Summary of the invention
The technical problem to be solved by the present invention is to overcome defect described above, provide a kind of safe and accurate, connection side
Circuit breaker arc camera system of the formula simply based on vibration triggering.
In order to solve the technical problem, a kind of circuit breaker arc camera system based on vibration triggering of the present invention,
Including vibrating sensor, high-speed camera and computer, the vibrating sensor uses all-metal integration cast aluminium shell and independence
Power supply power supply design, the vibrating sensor is fixed on the framework of breaker, the vibrating sensor by BNC line with it is described
The triggering port of high-speed camera connects, and the high-speed camera is connect by data line with the computer；Breaker carries out point/
When closing operation, breaker high vibration issues vibration signal, and the vibrating sensor collects the vibration letter of breaker sending
Number and trigger the high-speed camera and shot using receiving the vibration signal moment as trigger time, the high-speed camera is clapped
The video information taken the photograph is sent to the computer by data line, by the computer to video captured by the high-speed camera
It is observed.
Preferably, computer of the present invention is laptop.
The present invention is difficult to capture the status with observation for circuit breaker electric magnetostatic wave signal, and proposition passes through in breaker actuation
Vibrating sensor trigger high-speed camera, capture electric arc from generate to extinguishing complete procedure and shot, utilize notebook
Computer observes entire arc extinguishing process, compares and analyzes, and switching arc when realizing circuit-breaker switching on-off is from generating extinguishing
The shooting and observation of complete procedure.
When existing circuit-breaker switching on-off for the observation method and device of switching arc, the present invention realize with
It is lower the utility model has the advantages that 1. using vibrating sensor when circuit-breaker switching on-off operates high vibration and the vibration signal that generates trigger it is high
Fast video camera carries out the means of electric arc shooting, and for manual shooting, it is accurate that shooting time point is held, and will not miss electric arc
From the whole process generated to extinguishing；2. since the vibration signal triggering high-speed camera issued by vibrating sensor is clapped
It takes the photograph, the safe distance of operator and breaker can be greatly increased, not only reduce manual operation amount, it is often more important that reduce
Personal dangerousness.
Detailed description of the invention
Fig. 1 is the associated components connection schematic diagram of electric arc camera system of the present invention.
Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and examples.
A kind of circuit breaker arc camera system based on vibration triggering of the present invention, including vibrating sensor 1, take the photograph at a high speed
