Description
Technical field
The utility model belongs to electrical equipment more particularly to a kind of detection system of breaker.
Background technique
Breaker primarily serves electric current in power grid and cut-offs function, when there are need to open and close by breaker when failure for power grid
Fault current guarantees the safety of power grid.The breaker electrically and mechanically state complicated as one, mechanical-like when divide-shut brake
State is of great significance to the reliability service of breaker, once the machine performance of breaker goes wrong, it is likely that lead to it
Malfunction or refused action, lead to the generation of accident.Machine performance when therefore to the machine performance, especially divide-shut brake of breaker
Carrying out detection is to guarantee the important measures of its safe operation.
The prior art lacks a kind of detection system that working state of circuit breaker can be detected in conjunction with many factors.
Utility model content
The purpose of the utility model is to provide a kind of detection systems of breaker, can be in conjunction with many factors detection open circuit
The working condition of device, testing result are more acurrate.
To solve the above problems, the technical solution of the utility model are as follows:
A kind of detection system of breaker, comprising:
First current sensor, the current signal of the opening coil for detecting the breaker are denoted as the first electric current letter
Number;
Second current sensor, the current signal of the closing coil for detecting the breaker are denoted as the second electric current letter
Number;
Vibrating sensor, at the shell of the ontology of the breaker, and position corresponds to the contact of the breaker,
The vibrating sensor is used to detect the vibration signal of the ontology of the breaker when circuit-breaker switching on-off;
Oscillograph, for showing the sheet of first current signal, second current signal and the breaker simultaneously
The vibration signal of body.
According to an embodiment of the present invention, the frequency range of the vibrating sensor is 1-10KHz.
According to an embodiment of the present invention, the sample rate of the oscillograph is not less than 1GHz, and bandwidth is not less than 200MHz.
According to an embodiment of the present invention, first current sensor and second current sensor are Hall
Current sensor.
The utility model due to using the technology described above, has the following advantages that it compared with prior art and actively
Effect:
The detection system of breaker in an embodiment of the present invention passes through while detecting the electric current letter of divide-shut brake coil
Number and breaker vibration signal and shown by oscillograph, then can comparative analysis once mechanical defect occurs in breaker
The wave character of two class signals, to improve the reliability and accuracy of fault diagnosis.
Detailed description of the invention
Fig. 1 is a kind of block diagram of the detection system of breaker of the utility model.
Specific embodiment
Below in conjunction with the drawings and specific embodiments to the utility model proposes the detection system of breaker a kind of make into one
Step is described in detail.According to following explanation and claims, will be become apparent from feature the advantages of the utility model.
Referring to Fig. 1, a kind of detection system of breaker, comprising: the first current sensor, for detecting the separating brake of breaker
The current signal of coil is denoted as the first current signal;Second current sensor, the electric current of the closing coil for detecting breaker
Signal is denoted as the second current signal;Vibrating sensor, at the shell of the ontology of breaker, and position corresponds to breaker
Contact, vibrating sensor is used for the vibration signal of the ontology of breaker when detecting circuit-breaker switching on-off;Oscillograph, for simultaneously
Show the vibration signal of the ontology of the first current signal, the second current signal and breaker.
It is appreciated that when breaker breaks down, the opening coil of breaker or current signal on closing coil and
Current signal when normal can be variant, and the shell of breaker also will appear abnormal vibrations.Breaker in the present embodiment
Detection system passes through while detecting the current signal of divide-shut brake coil and the vibration signal of breaker and being shown by oscillograph
Show, once there is mechanical defect in breaker, then can two class signal of comparative analysis wave character, to improve fault diagnosis
Reliability and accuracy.
Further, the frequency range of vibrating sensor is 1-10KHz.
Further, the sample rate of oscillograph is not less than 1GHz, and bandwidth is not less than 200MHz.
Further, the first current sensor and the second current sensor are Hall current sensor.
The embodiments of the present invention is explained in detail above in conjunction with attached drawing, but the utility model is not limited to
Above embodiment.Even if to the utility model, various changes can be made, if these variations belong to the utility model claims
And its within the scope of equivalent technologies, then still fall among the protection scope of the utility model.
