Abstract
Disclosed is a synchronous detector which is convenient to operate and use. The synchronous detector includes a power supply. The power supply includes a direct-current (DC) power supply and an alternating-current (AC) power supply which are mutually connected in a parallel way. A DC indication light is serially connected with a circuit which the DC power supply is in and an AC indication light is serially connected with a circuit which the AC power supply is in. One end of the power supply is electrically connected with an AC-DC converter which is serially connected with a three-phase circuit breaker through a circuit. And a contact point and a signal indication light are serially connected between each phase of the three-phase circuit breaker and the other end of the power supply respectively. Three 1.5V batteries or a 220V AC power supply is selected in the synchronous detector as needed. In use, corresponding yellow, green and red wires are connected at two sides of the circuit breaker or a vacuum tube and the vacuum breaker is switched on step by step so that asynchronous phases can be detected visually through twinkling of bulbs and then adjustment is made until three-phase contacts of the vacuum tube are synchronous. Detection work of maintenance personnel is greatly facilitated.
Description
Technical field
The present invention relates to a kind of detecting instrument, relate in particular to a kind of vacuum circuit breaker synchronous detecting instrument.
Background technology
The vacuum circuit breaker of ground transformer substation high-tension switch cabinet and down-hole vacuum switch vacuum tube, because the deviation that naked eyes can't detect can appear in the long-term three-phase contact that uses, will cause disconnected mutually tripping operation or false leakage tripping when excessive when opening, safe power supply work to mine has brought great hidden danger, do not have instrumentation to detect, often be difficult to judge accident point.Traditional monitoring method is to utilize multimeter to measure one by one each phase, and whether synchronous, measure very inconvenient if can not measure simultaneously vacuum switch vacuum tube three-phase contact, the result is inaccurate, often judge inaccurate trouble spot, prolong the accident treatment time, restricting to a certain extent mine safety production.
Summary of the invention
The present invention is directed to deficiency, a kind of synchronous detecting instrument easy for operation is provided.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
A kind of synchronous detecting instrument, comprise power supply, it is characterized in that, power supply includes direct supply parallel with one another and AC power, be in series with d. c. indicator light 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 by circuit, is in series with respectively contact point and signal lamp between each of three-phase breaker and the power supply other end.
The invention has the beneficial effects as follows:
The present invention can select 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 intuitively asynchronous phase by the glittering of bulb, then adjust, until whether vacuum tube three-phase contact is synchronous, greatly facilitate maintainer's inspection work.
Description of drawings
Fig. 1 is structural representation of the present invention.
In the accompanying drawing:
1, AC/DC converter; 2, direct supply; 3, AC power; 4, d. c. indicator light; 5, exchange pilot lamp; 6, signal lamp; 7, contact point; 8, three-phase breaker.
Embodiment
Below in conjunction with accompanying drawing principle of the present invention and feature are described, institute gives an actual example and only is used for explaining the present invention, is not be used to limiting scope of the present invention.
A kind of 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, be in series with d. c. indicator light 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, AC/DC converter 1 is in series with three-phase breaker 8 by circuit, is in series with respectively contact point 7 and signal lamp 6 between each of three-phase breaker 8 and the power supply other end.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
When using detection failure of the present invention, at first select 1.5 volts of batteries, 3 joints 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 respectively isolating switch or vacuum tube both sides, be transformed on the needed power circuit by AC/DC changeover switch, observe the glittering of bulb and can detect intuitively synchronous or asynchronous phase, then adjust, until vacuum tube three-phase contact is synchronous.
This method of testing is simple and clear, simple operation, and the instrument carrying portable can accurately be judged 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 in uncharged situation synchronous, can either guarantee maintenance personal's personal safety, can process accurately and conveniently again the nonsynchronous fault of vacuum tube three-phase contact.
