Abstract
The utility model discloses a transformer temperature measurer which comprises an optical fiber temperature measuring probe (1) which is connected with a receiver (2); the receiver (2) is connected with a PID controller (3); the PID controller is connected with a heating coil (4); the other end of the heating coil (4) is connected with the PID controller (3); and the heating coil (4) is also connected with a temperature displayer. The transformer temperature measurer can bear high temperature and resist the corrosion and strong electromagnetic interference, and also can directly detect the interior temperature of the transformer, timely react and process the failure.
Description
Technical field
The utility model relates to a kind of thermal detector, particularly a kind of transformer thermal detector.
Background technology
Present transformer thermal detector is not that directly the thermometric degree is come in contact survey transformer inside, but temperature probe is placed on voltage device top, its resulting temperature value is to produce by the oily temperature that measures being carried out the electronics conversion, it or not the true temperature of voltage device, accurate reaction oil temperature, this can not in time react the situation that transformer in use takes place, and then can not control and handle the fault that transformer takes place automatically.
The utility model content
Technical problem to be solved in the utility model provides a kind ofly can directly be surveyed the transformer internal temperature and can in time react transformer thermal detector with handling failure, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: a kind of transformer thermal detector, it comprises the optical fiber temperature-measurement probe, the optical fiber temperature-measurement probe is connected with receiver, receiver links to each other with the PID controller, the PID controller links to each other with heater coil, the heater coil other end is connected with the PID controller, and heater coil also is connected with temperature indicator.
Receiver links to each other with the transformer life counter, and the transformer life counter links to each other with the transformer life display.
Be provided with pointer in the temperature indicator, offer several induction modules at the edge branch that pointer can touch.
The quantity of induction module is 3.
Compared with prior art, the utility model is by popping one's head in optical fiber temperature-measurement around arriving the inner direct temperature measurement of transformer, resulting data are received processing, by the current flow heats coil resulting temperature is shown on the temperature indicator again, owing to be high pressure resistant, the anticorrosive and strong electromagnetic of fibre-optical probe energy; Receiver links to each other with the transformer life counter, and the transformer life counter links to each other with the transformer life display, can be used for showing transformer serviceable life; Temperature indicator reflects temperature by the pointer indicating graduation, temperature indicator inside is provided with three induction modules, pointer contacts first induction module when temperature reaches certain value, the circuit of electric fan will be opened transformer is lowered the temperature, continue to raise when pointer touches second induction module, the circuit of alarm is just opened people is warned, and continues to raise when pointer touches the 3rd induction module, and power supply will disconnect.
