Abstract
The utility model discloses a vacuum circuit breaker synchronous detector which is convenient to operate and use and comprises a power supply, the power supply comprises a direct current power supply and an alternative current power supply connected in parallel, the circuit of the direct current power supply is connected with a direct current indicator light in series, the circuit of the alternative power supply is connected with an alternative current indicator light in series, one end of the power supply is connected to an alternative current/direct current converter which is also connected to a three-has breaker in series through a circuit, and a contact and a signal indicator light are connected between every phase of the three-phase breaker and the other end of the power supply in series. According to the vacuum circuit breaker synchronous detector, three 1.5V batteries or 220V alternative current power supply can be selected as required. When the vacuum circuit breaker synchronous detector is used, the corresponding yellow wire, green wire and red wire are connected to the breaker or at the two sides of the vacuum tube so as to gradually switch on the vacuum breaker, different steps can be directly detected by the lighting of the bulb, then regulation is performed till the three-phase contact of the vacuum tube are synchronized, thereby greatly facilitating the inspection of the maintainer.
Description
Technical field
The utility model relates to a kind of detecting instrument, relates in particular to a kind of vacuum circuit breaker synchronous detecting instrument.
Background technology
The vacuum circuit breaker of ground electric substation high-tension switch cabinet and down-hole vacuum switch vacuum tube; Because of long-term use the three-phase contact naked eyes can occur can't detected deviation; Will cause phase failure tripping operation or false leakage tripping when excessive when opening; Safe power supply work to mine has brought great hidden danger, does not have instrumentation to detect, and often is difficult to judge accident point.Traditional monitoring method is to utilize multimeter to measure each phase one by one, and whether can not measure vacuum switch vacuum tube three-phase contact simultaneously synchronous, measures very inconvenient; The result is inaccurate; Often judge inaccurate trouble spot, prolong the accident treatment time, restricting mine safety production to a certain extent.
The utility model content
The utility model provides a kind of vacuum circuit breaker synchronous detecting instrument easy for operation to not enough.
The technical scheme that the utility model solves the problems of the technologies described above is following:
A kind of vacuum circuit breaker synchronous detecting instrument comprises power supply, it is characterized in that; Power supply includes direct supply parallel with one another and AC power; Be in series with the direct current pilot lamp in the circuit at direct supply place, be in series with the interchange pilot lamp in the circuit at AC power place, power supply one end is electrically connected with the AC/DC converter; The AC/DC converter is in series with three-phase breaker through circuit, is in series with contact point and signal lamp respectively between each of three-phase breaker and the power supply other end.
The beneficial effect of the utility model is:
The utility model can be selected 1.5 volts of batteries 3 joint as required, perhaps 220V AC power (in transformer is arranged, primary side 220V, secondary side 4.5V).During use corresponding yellowish green red line is connected to isolating switch or vacuum tube both sides; Progressively connect vacuum circuit breaker, can detect asynchronous phase intuitively, adjust then through the glittering of bulb; Whether synchronous until vacuum tube three-phase contact, greatly facilitate maintainer's inspection work.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing:
1, AC/DC converter; 2, direct supply; 3, AC power; 4, direct current pilot lamp; 5, exchange pilot lamp; 6, signal lamp; 7, contact point; 8, three-phase breaker.
Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
A kind of vacuum circuit breaker synchronous detecting instrument; As shown in Figure 1; Comprise power supply, power supply includes direct supply parallel with one another 2 and AC power 3, is in series with direct current pilot lamp 4 in the circuit at direct supply 2 places; Be in series with in the circuit at AC power 3 places and exchange pilot lamp 5; Power supply one end is electrically connected with AC/DC converter 1, and AC/DC converter 1 is in series with three-phase breaker 8 through circuit, is in series with contact point 7 and signal lamp 6 between each of three-phase breaker 8 and the power supply other end respectively.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
When using the utility model detection failure, at first select 1.5 volts batteries 3 to save according to line switching, load character, perhaps the 220V AC power (in transformer is arranged; Primary side 220V, secondary side 4.5V), then corresponding yellowish green red line is connected to isolating switch or vacuum tube both sides respectively; Be transformed on the needed power circuit through AC/DC changeover switch; Observe the glittering of bulb and can detect intuitively synchronously or asynchronous phase, adjust then, synchronous until vacuum tube three-phase contact.
This method of testing is simple and clear, simple operation, and instrument carries light, can accurately judge accident point, shortens the accident maintenance time, greatly facilitates maintainer's inspection.Whether the electrical repair personnel can detect, adjust vacuum switch vacuum tube three-phase contact under uncharged situation synchronous, can either guarantee maintenance personal's personal safety, can handle the nonsynchronous fault of vacuum tube three-phase contact again accurately and conveniently.
