Abstract
The invention discloses a 10 kV vacuum circuit breaker opening time on-load automatic testing method. A normally-closed contact of a circuit breaker auxiliary switch is connected to one end of a time tester, a normally-opened contact of an electrified displayer is connected to the other end of the time tester to form a starting loop for measuring opening time, and the opening time of the vacuum circuit breaker is measured. When the circuit breaker is opened, the normally-closed contact of the auxiliary switch is closed (the circuit breaker is located at the closing position and the normally-opened contact of the electrified displayer is closed), the starting loop of the time tester is connected, the normally-opened contact of the electrified displayer is opened after the circuit breaker is opened, the starting loop of the time tester is disconnected, and measured time difference is the opening time of circuit breaker. After the 10 kV vacuum circuit breaker opening time on-load automatic testing method is adopted, real-time online monitoring can be performed on the circuit breaker, vacuum degree state analysis can be performed by comparing opening time parameters, and safe and reliable operation in a complete period of a device is ensured.
Description
Technical field
The present invention relates to power transformation switch testing field, more particularly to a kind of 10kV vacuum circuit breakers opening time on-load
Automatic test approach.
Background technology
10kV breaker routine test interval times are 6 to 9 years.Breaker long-play, particularly 10kV electric capacity break
The frequently division automatically of road device, being susceptible to vacuum reduces or punctures, it is impossible to correctly cut-off load current and short circuit current.If
Vacuum is reduced or punctured, and separating brake actuation time must be increased when cut-offfing load current and short circuit current, can not be gone out when serious
Arc causes breaker to explode.
The content of the invention
In order to realize breaker open operation time real time on-line monitoring, a kind of 10kV vacuum circuit breakers opening time band is developed
Load automatic test approach, can carry out real time on-line monitoring, by opening time parameter using after this kind of method to breaker
Comparison, the state analysis of vacuum can be carried out, it is ensured that equipment complete period safe and reliable operation.
The 10kV vacuum circuit breaker opening time on-load automatic test approach that the present invention is provided, uses auxiliary switch for circuit breaker
Normally-closed contact is connected to one end of time tester, and electrification display normally opened contact is connected to the other end of time tester and constitutes measurement
The starting-up later time of opening time, measures to vacuum circuit breaker opening time, and when breaker open operation, auxiliary switch is normally closed touches
Point closure, the starting-up later time of (breaker is closed in closing position electrification display normally opened contact) turn-on time tester breaks
Electrification display normally opened contact is opened after the device separating brake of road, the starting-up later time of turn-off time tester, and the time difference of this measurement is just
It is the breaker open operation time.
According to the present invention, real time on-line monitoring can be carried out to breaker using after this kind of method, by joining to opening time
Several comparisons, can carry out the state analysis of vacuum, it is ensured that equipment complete period safe and reliable operation.

Many details are elaborated in the following description in order to fully understand the present invention, but, the present invention may be used also
Implemented with being different from other modes described here using other, therefore, the present invention is not limited to following public concrete reality
Apply the restriction of example.
Fig. 1 shows that 10kV vacuum circuit breakers opening time on-load automatic test approach of the invention is used
The schematic diagram of the embodiment of individual system.In figure, RF is capacitive divider, and K is little switch.
As illustrated, the 10kV vacuum circuit breaker opening time on-load automatic test approach that the present invention is provided, with open circuit
Device auxiliary switch FZ normally-closed contacts are connected to one end of time tester SJC, and the normally opened contact of electrification display DX1, DX2, DX3 connects
The other end to time tester SJC constitutes the starting-up later time of measurement opening time, and vacuum circuit breaker opening time is surveyed
Amount, the auxiliary switch normally-closed contact closure when breaker open operation, (breaker is closed in closing position electrification display normally opened contact
Close) starting-up later time of turn-on time tester SJC, electrification display normally opened contact is opened after breaker open operation, and turn-off time surveys
The starting-up later time of examination instrument SJC, the time difference of this measurement is exactly the breaker open operation time.
According to the present invention, real time on-line monitoring can be carried out to breaker using after this kind of method, by joining to opening time
Several comparisons, can carry out the state analysis of vacuum, it is ensured that equipment complete period safe and reliable operation.
The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
