Abstract
The utility model relates to a polarity tester for a current transformer and belongs to the application field of electric power. The polarity tester for the current transformer is characterized in that an anode of a test power is connected with a P1 terminal of a primary coil of the current transformer, and a cathode of the test power is connected with a P2 terminal of the primary coil of the current transformer; an anode of a current meter is connected with an S1 terminal of a secondary coil of the current transformer, and a cathode of the current meter is connected with an S2 terminal of the secondary coil of the current transformer; and when a test button is pressed down, the loop circuit of the test power is switched on, and a test lamp lights on. The polarity tester for the current transformer has the advantages of light weight, small size and good functional property, is easy to wire and convenient to carry, and can replace the existing test equipment for checking the current transformer so as to shorten the protection test period and reduce the workload, thereby greatly improving the fieldwork efficiency, relieving the workload of the workers, and shortening the construction period of completing the tasks such as new construction of a transformer substation and integrated automation transformation.
Description
Technical field
The utility model relates to a kind of tester, relates in particular to a kind of current transformer polarity tester, belongs to the electric power application.
Background technology
At relay protection professional work character; when newly-built transformer station and replacing current transformer; verification current transformer polarity is a requisite pilot project; but because existing verification current transformer testing equipment volume is bigger, heavy; with the testing equipment scene of being transported to is a thing that wastes time and energy; inefficiency not only, and increased employee's workload.
Summary of the invention
The utility model is at above-mentioned problems of the prior art, provide a kind of light, small and exquisite, wiring is simple, the current transformer polarity tester that functional character is good, the problem that has wasted time and energy when having solved prior art lieutenant colonel's galvanoscope mutual inductor, and the utility model is safe and reliable, and cost is low, has reduced labour intensity.
The technical solution of the utility model is as follows:
The positive pole of experiment power supply is connected on the P1 terminal of current transformer primary winding, the negative pole of experiment power supply is connected on the P2 terminal of current transformer primary winding, the positive pole of reometer is connected on the secondary coil S1 end of current transformer, and the negative pole of reometer is connected on the secondary coil S2 end of current transformer; When pressing test button, the loop of experiment power supply is connected, and test burner is bright.
Described reometer is pointer reometer.
Described experiment power supply is a rechargeable battery.
The utility model has the advantages of as follows:
1, the utility model is light, small and exquisite; wiring is simple; easy to carry; functional character is good, can replace existing verification current transformer testing equipment, and the protection test time is shortened; workload reduces; improved work on the spot efficient greatly, alleviated the employee work amount, for finishing newly-built transformer station and combining from tasks such as transformations and shortened the duration.
2, experiment power supply of the present utility model adopts rechargeable battery, has reduced cost, energy-conserving and environment-protective.
3, the utility model scene can be keeped in repair, and saves cost, the delay man-hour of having avoided tester of the prior art to need depot repair to bring, the problem that maintenance cost is high.
Description of drawings
Fig. 1 is a planar structure synoptic diagram of the present utility model.
Fig. 2 is a principle wiring schematic diagram of the present utility model.
Among the figure, 1, test burner, 2, reometer, 3, test button, 4, experiment power supply, P1, P2, S1, S2 are connection terminal.
Embodiment
The utility model in conjunction with specific embodiments, is described in detail as follows with reference to accompanying drawing.
Embodiment
Detect the current transformer polarity chron, the positive pole of battery 4 is connected on the P1 terminal of current transformer primary winding, the negative pole of battery 4 is connected on the P2 terminal of current transformer primary winding, and the positive pole of pointer reometer 2 is connected on the Current Transformer Secondary coil S1 end, the negative pole of pointer reometer 2 is connected on the secondary coil S2 end of current transformer.When pressing test button 3, the loop of battery 4 is connected, test burner 1 is bright, pointer-type reometer 2 pointers deflection right-hand rotations (positive dirction), and when unclamping test button 3, test burner 1 goes out, and pointer reometer 2 pointers then are partial to left-hand rotation (in the other direction), show that then the P1 end that current transformer is connected on the anode is same polarity with the S1 end that is connected on the reometer positive pole, promptly P1, S1 are same polarity.With above-mentioned opposite, be heteropolarity as the swing of ammeter pointer, the scene of not meeting makes the standard of Current Transformer, need more renew current transformer.
Claims (3)
1. current transformer polarity tester, the positive pole that it is characterized in that experiment power supply is connected on the P1 terminal of current transformer primary winding, the negative pole of experiment power supply is connected on the P2 terminal of current transformer primary winding, the positive pole of reometer is connected on the secondary coil S1 end of current transformer, and the negative pole of reometer is connected on the secondary coil S2 end of current transformer; When pressing test button, the loop of experiment power supply is connected, and test burner is bright.
2. current transformer polarity tester according to claim 1 is characterized in that described reometer is pointer reometer.
