Description
Technical field
The utility model relates to a kind of comprehensive protector for the high-voltage frequency-conversion phase-shifting transformer.
Background technology
The high pressure phase shifting transformer is the power unit of high voltage converter, and technology is only carried out temperature survey mutually to three groups of inputs of transformer at present, the temperature impact that this operating load state that can only observe statically frequency converter causes transformer.In actual motion, cause the reason of high voltage converter fault often to occur in winding overload or the short circuit that certain power cell is corresponding, the consequence that this overload or short circuit cause is the scaling loss of Transformer Winding, even burning, existing technology can't detect this, even detect once in a while, all also produced in the situation of serious consequence, all breaking out of fires.
The utility model content
The purpose of this utility model is in order to provide a kind of energy minimizing accident that the comprehensive protector for the high-voltage frequency-conversion phase-shifting transformer of equipment heavy losses occurs, prevents.
In order to reach the purpose of this utility model, technical scheme is as follows:
A kind of comprehensive protector for the high-voltage frequency-conversion phase-shifting transformer; be provided with several windings in described high-voltage frequency-conversion phase-shifting transformer; described comprehensive protector comprise comprehensive protection device and with described winding attemperating unit one to one; described attemperating unit comprises temperature detect switch (TDS) and optical coupler; the input of described optical coupler is connected with the output of described temperature detect switch (TDS); the output of described optical coupler is connected with described comprehensive protection device, and described temperature detect switch (TDS) is arranged on the outer surface of described winding.
Further, also comprise the smoke detector that several are connected with described comprehensive protection device.
Further, between described optical coupler and described temperature detect switch (TDS), be provided with power supply, the two ends of described power supply are connected with described optical coupler and described temperature detect switch (TDS) respectively.
Comprehensive protection device can processing signals, and is provided with the outputs such as output, serial ports output, digital output, control output of reporting to the police.
The temperature of each unit winding can detect by being arranged on its surperficial temperature detect switch (TDS), and temperature detect switch (TDS) sends temperature signal to comprehensive protection device by optical coupler, and comprehensive protection device is processed signal, produces corresponding output.If excess Temperature, comprehensive protection device can send the output of reporting to the police.By such configuration, can the very first time find fault point, when just going wrong, trouble unit just provides alert, and make the technical staff can find in time fault point, the expansion of avoiding fault is the generation of accident.
Be provided with for example power supply of dry cell and so between temperature detect switch (TDS) and optical coupler, the input of power supply, temperature detect switch (TDS) and optical coupler has formed an independently loop, and operation is more stable and permanent.
By smoke detector is set, smog when smoke detector can be to fiery residence is detected, and transmits signal to comprehensive protection device, and then makes comprehensive protection device produce the output of reporting to the police.Operating personnel are judged in time, cut off the electricity supply, avoid the generation of fire.
Simultaneously, comprehensive protection device has the output of control, can be corresponding with Emergency treatment System, when reaching the extent of injury of setting, start the automatic emergency treatment system.
The beneficial effect the utlity model has:
Greatly reduce short circuit, the overload accident of high voltage converter, stopped disaster hidden-trouble, avoided the heavy losses of equipment, guaranteed the continuity of producing.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model comprehensive protector.
Embodiment
Below in conjunction with embodiment, the utility model is further described, but protection range of the present utility model not only is confined to embodiment.
As shown in Figure 1, a kind of comprehensive protector for the high-voltage frequency-conversion phase-shifting transformer, be provided with several windings in the high-voltage frequency-conversion phase-shifting transformer.Comprehensive protector comprise comprehensive protection device 1 and with winding attemperating unit one to one; attemperating unit comprises temperature detect switch (TDS) and optical coupler; the input of optical coupler is connected with the output of temperature detect switch (TDS); the output of optical coupler is connected with comprehensive protection device 1, and temperature detect switch (TDS) is arranged on the outer surface of winding.
Comprehensive protection device 1 also is connected with several smoke detectors 2, and the quantity of smoke detector 2 is determined according to space, and preferably 2～4, in the present embodiment, smoke detector 2 has 4.
Be provided with power supply between optical coupler and temperature detect switch (TDS), the two ends of power supply are connected with optical coupler and temperature detect switch (TDS) respectively, and the input of power supply, temperature detect switch (TDS) and optical coupler has formed an independently loop.
Finally it should be noted that: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model, therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, and all do not break away from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in claim scope of the present utility model.
