Abstract
The utility model discloses a vacuum contactor synchronization tester, comprising a transformer, wherein the output end of the first secondary coil of the transformer is connected with the input end of a rectification circuit, the output end of the rectification circuit is connected with three multipled test indication circuits, each test indication circuit comprises an indication lamp and a vacuum tube binding post, and the output end of the second secondary coil of the transformer is used for connecting with the coil of a vacuum contactor. The vacuum contactor synchronization tester can determine whether the three phases of the vacuum tube contactor are synchronous or not, and then the spacing of the vacuum tube contactor is adjusted through ocular estimation or marking, until the three phases of the vacuum tube contactor are synchronous. The vacuum contactor synchronization tester is easy in manufacture, low in cost, simple in operation and convenient in maintenance.
Description
Technical field
The utility model relates to a kind of pick-up unit, relates in particular to a kind of synchrometer for vacuum contactor.
Background technology
Vacuum magnetic starter is on coal mine, one of down-hole electric equipments, on the digging Transport Machinery is controlled, be used widely, the unfavorable factors such as, frequent movement poor due to service condition, Fraquent start, be in operation and occur than multiple faults, often burn motor, affect to a certain extent safe handling, for enterprise causes no small loss.
For effectively controlling its fault, fully accomplish preventative maintenance.The means that check commissioning device are particularly important.At present, the synchrometer of selling on market uses loaded down with trivial details, is prone to fault, and price is higher.According to statistics, the classification of scene to the magnetic starter accident, the highest place of failure rate is just on the three-phase vacuum tube of vacuum A. C. contactor, account for more than 80% of total accident, through testing and analyzing: former because the pressure spring of vacuum tube is after using after a while, different variations occur in three pressure spring degree of fatigues, cause the asynchronous adhesive of vacuum tube contact three-phase or adhesive after contact pressure different.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of vacuum contactor synchrometer, can judge according to the bright light order of tester pilot lamp whether the vacuum tube adhesive is synchronous.
The technical solution adopted in the utility model is:
A kind of vacuum contactor synchrometer, comprise transformer, the output terminal of described transformer the first secondary coil connects the input end of rectification circuit, the output terminal of rectification circuit connects the test indicating circuit of three tunnel parallel connections, and every drive test examination indicating circuit comprises pilot lamp and the vacuum tube connection terminal of series connection; The output terminal of described transformer second subprime coil is used for connecting the vacuum contactor coil.
Described vacuum contactor synchrometer also comprises the adjustable resistance voltage divider and the voltage table that are connected in the second subprime coil output.
Described vacuum contactor synchrometer also comprises the polar capacitor for filtering, is connected in the output terminal of rectification circuit.
The sequencing that the utility model is lighted according to three pilot lamp judges whether the vacuum tube contact is synchronous, then uses range estimation or makes marks and carry out the opening apart from adjusting, until reach synchronous of vacuum tube; This device is easily made, cost is low, simple to operate, easy to maintenance.
Description of drawings
Fig. 1 is schematic block circuit diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises transformer T, the output terminal of described transformer T the first secondary coil P1 connects the input end of rectification circuit D, the output terminal of rectification circuit D connects the test indicating circuit of three tunnel parallel connections, and every drive test examination indicating circuit comprises pilot lamp D1, D2, D3 and vacuum tube connection terminal S1, S2, the S3 of series connection; The output terminal of described transformer T second subprime coil P2 is used for connecting vacuum contactor coil SQ; Second subprime coil P2 output terminal connects adjustable resistance voltage divider RT and voltage table V; The output terminal of rectification circuit D also connects the polar capacitor for filtering.
When vacuum contactor synchrometer works, first carry out the preliminary work before detecting, at first the first K switch 1, K switch 3 are in off-state, vacuum tube connection terminal S1, S2, the S3 of vacuum contactor synchrometer are connected to the test section, U switches on power, then close a switch K3, the first K switch 1, preliminary work finishes; During work, the second switch K2 that closes, contactor coil SQ energising by adjusting the voltage at adjustable resistance voltage divider RT adjusting contactor coil SQ two ends, reaches rated voltage, can show that registration is definite according to voltage table V.Three vacuum tube adhesives this moment, in attracting process can according to three pilot lamp judge three vacuum tubes whether synchronous or some leading, lag behind; Then the distance of opening of three vacuum tubes is adjusted, can be used range estimation or make marks and carry out, adjust clearance between open contacts according to error, until reach synchronous.
