Description

Integrated transformer current transformer associating termination
Technical field
The utility model relates to transformer technology field, is specifically related to a kind of integrated transformer current transformer associating termination.
Background technology
At present, the instrument transformer of the metering transformer of prior art be all located at the low tension terminal of a, b, c phase outlet wire on or be located in counter box; The shortcoming of this metering transformer is easily from hanging wire stealing low tension terminal, causes electric quantity loss, particularly the interim hanging wire of short-term, be difficult to find to power supply enterprise.Also have and be arranged on by current transformer the generation that inside transformer mode carrys out electricity theft prevention phenomenon, but should be noted that a lot of problem like this, the heat dissipation problem of transformer own is just very large, more strict for the monitoring of temperature when current transformer is arranged on inside transformer, the generation of Accident prevention.And during circuit secondary side open circuit, very high overvoltage can be produced, and the person and equipment are threatened, therefore very important to the monitoring and protecting of current transformer.
Utility model content
Problem to be solved in the utility model is to provide a kind of integrated transformer current transformer associating termination; current transformer is arranged transformer-cabinet inside; stopped the generation of stealing electricity phenomenon, and the infrared temperature sensor of inner setting and overvoltage protection device play the effect of temperature monitoring and equipment protection to equipment.
A kind of integrated transformer current transformer associating termination, comprise casing, in described casing, transformer body is set, above described casing, current transformer is set, described current transformer is arranged on the low tension terminal of described transformer body, the low-voltage coil of described transformer body and described current transformer are arranged with secondary wiring terminals and are connected, described secondary winding in current transformer two ends are connected with overvoltage protection device, in described casing, infrared temperature sensor is set, described infrared temperature sensor is connected with controller, described controller is connected with communication module.
Further, described overvoltage protection device comprises piezo-resistance.
Further, described controller comprises dsp chip.
Further, described communication module comprises DTU digital transmission module.
The utility model provides a kind of integrated transformer current transformer associating termination, comprise casing, in described casing, transformer body is set, above described casing, current transformer is set, described current transformer is arranged on the low tension terminal of described transformer body, the low-voltage coil of described transformer body and described current transformer are arranged with secondary wiring terminals and are connected, described secondary winding in current transformer two ends are connected with overvoltage protection device, in described casing, infrared temperature sensor is set, described infrared temperature sensor is connected with controller, described controller is connected with communication module.Current transformer is arranged on the generation that box house can stop stealing electricity phenomenon; overvoltage protection device can protective current instrument transformer; because charged secondary winding in current transformer forbids open circuit operation; the number of turn of secondary is relatively once a lot; when secondary winding open circuit can produce very high overvoltage; the person and equipment are threatened, so current transformer is forbidden to open a way, the safety that overvoltage protection device is beneficial to equipment is set.Infrared temperature sensor can carry out non-contact type temperature measurement to the equipment in casing; can monitor device temperatures such as transformer, current transformer, overvoltage protection devices; prevention temperature is too high; can when Current Transformer Secondary side goes wrong Timeliness coverage; accomplish that accident finds in advance, the generation of prevention major accident.
Described overvoltage protection device comprises piezo-resistance.When secondary winding in current transformer short circuit or when being connected to load, because the voltage at secondary winding two ends is very low, piezo-resistance presents high resistance, does not have electric current to flow through protector, does not affect the normal operation of instrument transformer.When secondary winding open circuit produces overvoltage, piezo-resistance is low resistance state, is equivalent to, secondary winding short circuit, so just inhibit superpotential generation, reaches the object of proterctive equipment and personal safety.
Described controller comprises dsp chip, the Harvard structure that the inside employing program of dsp chip and data are separated, has special hardware multiplier, extensively adopts pile line operation, special DSP instruction is provided, can be used for realizing various digital signal processing algorithm fast.Can control communication module and infrared temperature sensor, accept teleinstruction and implement.
Described communication module comprises DTU digital transmission module, and DTU digital transmission module adopts low power dissipation design, by GPRS or short message way remote transmission data, can carry out remote monitoring to the temperature of box house, its inner integrated ICP/IP protocol stack; Serial data bi-directional conversion function is provided; Support automatic heartbeat, keep permanent online; Convenient for temperature monitoring, disconnection reconnecting, the transmission stability of information is high, and promptness is high, easy to use.
The beneficial effects of the utility model: current transformer is arranged transformer-cabinet inside by the utility model; stop the generation of stealing electricity phenomenon; and the infrared temperature sensor of inner setting and overvoltage protection device play the effect of temperature monitoring and equipment protection to equipment; whole device is easy to use, improves the fail safe of electricity consumption.
