Abstract
The utility model discloses a kind of high-pressure vacuum contactor synchronism pick-up unit, comprise power supply, power light, power switch, parallel with one another three pilot lamp, described power supply, power light, power switch and parallel with one another three pilot lamp are cascaded and form loop, and on three parallel lines at described three pilot lamp places, be respectively arranged with two groups of receptacle contacts, described receptacle contacts draws wire respectively, and connects conductive clip at the free end of wire.Use the utility model can quick and precisely detect high-pressure vacuum contactor synchronism, simple to operate, easy to use, safe and reliable, small in volume, a people can carry operation, greatly increases work efficiency.
Description
Technical field
The utility model relates to a kind of circuit checker, particularly relates to a kind of high-pressure vacuum contactor synchronism pick-up unit.
Background technology
At present, high-pressure vacuum contactor is widely used with its excellent extinguishing arc characteristic, such as, high-pressure vacuum contactor can be adopted in hoister high-voltage motor as control element.The synchronism of high-pressure vacuum contactor is to guaranteeing that equipment safety operation aspect plays vital effect.Therefore, need the vacuum tightness making regular check on vacuum contact arc-chutes, vacuum contact arc-chutes are the most important parts of high-pressure vacuum contactor, and its vacuum tightness quality will directly have influence on the arc extinction performance of vacuum contactor.In real work, because the arc-chutes accident caused of leaking gas accounts for sizable ratio, detect when therefore the vacuum tightness of arc-chutes being necessary regularly to (on average at quarterly intervals or according to concrete service condition) or considering and may sustain damage.Former detection synchronism equipment is heavier is about 50kg, and carry inconvenience, debugging is complicated, wiring is loaded down with trivial details, use inconvenience, supply voltage becomes 36V from alternating current 220V, and output voltage is 36V then to use multimeter to confirm, voltage security performance is lower, debugging inconvenience, equipment use is unreliable, and display lamp is 100W incandescent lamp bulb, energy consumption is larger, one-stop operation needs 3 people's haulage equipments, and manpower and materials can not reasonable disposition, does not meet scientific energy saving.In addition, also need to make regular check on the over travel of vacuum contactor, three-phase synchronism and main contact abrasion condition, due to frequent operation or mechanical mechanism tired, cause the over travel of vacuum contactor mechanical mechanism and synchronism can be undesirable, work efficiency be lower.Its labour intensity is large, inefficiency, and operates dangerous.
Utility model content
The purpose of this utility model is for prior art Problems existing, provides a kind of high-pressure vacuum contactor synchronism pick-up unit.
Above-mentioned purpose is realized by following proposal:
A kind of high-pressure vacuum contactor synchronism pick-up unit, it is characterized in that, described pick-up unit comprises power supply, power light, power switch, parallel with one another three pilot lamp, described power supply, power light, power switch and parallel with one another three pilot lamp are cascaded and form loop, and on three parallel lines at described three pilot lamp places, be respectively arranged with receptacle contacts, described receptacle contacts draws wire respectively, and connect conductive clip at the free end of wire.
According to above-mentioned pick-up unit, it is characterized in that, described power supply is 18V dry cell.
According to above-mentioned pick-up unit, it is characterized in that, described three pilot lamp are respectively red, green, yellow.
The beneficial effects of the utility model: use the utility model can quick and precisely detect high-pressure vacuum contactor synchronism, simple to operate, easy to use, safe and reliable, greatly increase work efficiency.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model.
Embodiment
See Fig. 1, high-pressure vacuum contactor synchronism pick-up unit of the present utility model comprises power supply 1, power light 2, power switch 3, three pilot lamp 4 parallel with one another, 6, 7, power supply 1, power light 2, power switch 3 and parallel with one another three pilot lamp 4, 6, 7 are cascaded forms loop (as shown in Figure 1, pilot lamp 4 parallel with one another, 6, 7 integrally, one end connects power switch, one end connects power supply), and at three pilot lamp 4, 6, on three parallel lines at 7 places, be respectively arranged with two groups of receptacle contacts A1, B1, C1 and A2, B2, C2, this parallel line is made to be in off-state (marking 5 in figure).Draw wire (totally 6 wires, not shown) in all receptacle contacts, and connect conductive clip (not shown) at the free end of wire, conductive clip can be conventional crocodile chuck.
Power supply preferably adopts 18V dry cell.Three pilot lamp 4,6,7 are preferably respectively the pilot lamp of red, green, yellow three kinds of colors.
During use, receptacle contacts A1, conductive clip that B1, C1 are corresponding are connected to link on vacuum contactor moving contact, the conductive clip that receptacle contacts A2, B2, C2 are corresponding connects vacuum contactor and determines link under contact, manually close a floodgate vacuum contactor, moving contact displacement is contacted gradually and determines contact, if now red, green, yellow display lamp is taken up in order of priority and is lighted, then show the first conducting of first bright display lamp, rear bright then rear conducting.Show the different Walk of ABC three-phase, that is: synchronism is poor, need again adjust.Until for best simultaneously when red greenish-yellow three display lamps are lighted, prove that probe of contactor three-phase synchronism reaches requirement.
Claims (3)
