Abstract
The utility model provides a simple and useful high-voltage metering box verifier with good verifying effect. The technical scheme is that current sampling pincers (1) are connected with an electrical parameter measurer (3) and a voltage sampler (2), that the bottom of the voltage sampler (2) is connected with an insulating rod (9), while the top of the voltage sampler (2) is connected with a power supply (4) and a wireless transmitter (5), that the wireless transmitter (5) transmits a signal to a wireless receiver (6) via wireless transmission, and that the wireless receiver (6) is connected with a decoding and error calculating unit (7) which is connected with a pulse receiver (8). The high-voltage metering box verifier well resolves problems of inaccurate metering and incapable onsite online verification and is capable of verifying a high-voltage metering box while not cutting off electricity and not influencing normal operation of a user.
Description
Technical field
The utility model relates to a kind of instrument and meter calibration equipment, especially High-voltage measuring box tester.
Background technology
High-voltage measuring box be as electricity consumption than the charge standard of metering of large user, in accordance with regulations when annual check to determine it within accuracy rating, the instrument that the interests of protection user and power supply department are not suffered a loss.But because High-voltage measuring box directly links to each other with the high voltage supply net throughout the year, can not have a power failure at any time and carry out verification, High-voltage measuring box moves under harsh outdoor weather conditions throughout the year simultaneously, and its parameter is easy to generate variation, causes the inaccurate situation of metering to happen occasionally; Meanwhile owing to there is not tester, on-line testing makes user and power supply unit interests can not get guaranteeing at the scene.
Summary of the invention
The utility model provides a kind of simple and practical, High-voltage measuring box tester that verification is effective, and its technical scheme is: comprise that mainly current sampling pincers, voltage sampling, electric parameter measurement, power supply, wireless transmission, wireless receiving, decoding and error calculate and reception of impulse.The current sampling pincers connect electric parameter measurement and voltage sampling by lead, the bottom of voltage sampling is connected with insulating bar, top is connected with power supply and wireless transmission, wireless transmission is by being wirelessly transmitted to wireless receiving, wireless receiving is connected to decoding and error is calculated, and decoding and error are calculated and connected reception of impulse.The utility model has well solved the inaccurate and problem of on-line testing at the scene of metering, and it can carry out verification to High-voltage measuring box under the situation that does not have a power failure, do not influence the normal operation of user.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
Embodiment
The utility model provides a kind of simple and practical, High-voltage measuring box tester that verification is effective.Current sampling pincers 1 connect electric parameter measurement 3 and voltage sampling 2 by lead, the bottom of voltage sampling 2 connects insulating bar 9, top is connected with power supply 4 and wireless transmission 5, wireless transmission 5 is by being wirelessly transmitted to wireless receiving 6, wireless receiving 6 is connected to decoding and error calculates 7, and decoding and error are calculated 7 and connected reception of impulse 8.
During use, current sampling pincers 1 are hung on the tested circuit, current sampling signal, voltage sampling 2 signals, import measuring unit simultaneously into, after calculating, the electric current and voltage synchronized sampling draws voltage, electric current, active power, reactive power, power factor, parameters such as accumulative total electric weight, result of calculation is through 485/232 interface, import wireless transmission 5 modules into, be emitted to receiving trap, receiving trap receives the voltage of three measuring units, electric current, active power, reactive power, power factor, the accumulative total electric quantity signal by the reception of impulse unit 8 by the pulse signal of school electric energy meter by registering the current transformer ratio of High-voltage measuring box, the voltage transformer (VT) no-load voltage ratio, the meter constant information of electric energy meter, synthetic being presented on the display, 3-5 pulse after the beginning verification directly shows measuring error on the display.
