Description
Technical field
The present invention relates to a kind of Novel Temperature Controller calibration equipment.
Background technology
In the transformer of temperature controller widespread use and electric system, be divided into oil surface temperature controller and winding temperature controller, its Main Function just provides temperature indication, control and transmitted signal.When transformer temperature is high, send alerting signal, and start cooling system transformer is lowered the temperature, can't lower the temperature or during cooling system failure, provide trip signal, action tripping operation, the safety of protection transformer.So temperature controller is carried out verification, it is one of necessary means that guarantees the transformer equipment safe and stable operation.According to related request, temperature controller necessary verification in per 3 years once.
In practical work process, the applicant finds that there are a lot of difficulties in the verification of temperature controller: the first, the set point verification mode is unreasonable; On the K node that the break-make shelves of needs use multimeter are permanently connected at temperature controller, the buzzer that utilizes relay to connect, disconnect multimeter records the temperature temperature of set point.Doing like this wastes time and energy, and whole set point checking procedure continues more than 1 hour at least, and testing crew need stand in the original place always and measure break-make with multimeter, all is great consumption to people's muscle power and energy.And often owing to reasons such as site environment are noisy, set point has been connected, but does not hear the multimeter buzzer, has missed the time of record test figure, and the set point verification is forced to repeat.The second, can't check the quality of transmitter; Usually temperature controller dead electricity when the main transformer maintenance, the transmitter of temperature controller can't be exported the current signal of 4-20mA, so just can't measure output current with multimeter, can't check the quality of transmitter.Three, can't check the linearity output situation of platinum resistance thermometer sensor, PT100; Normal conditions, whether the resistance output that we check platinum resistance thermometer sensor, PT100 is accurately the time, just take out several calibration points and measure inspection, but after the long-time use of part platinum resistance thermometer sensor, PT100, it is unstable that output resistance becomes, originally linearity output becomes non-linear, so that the selective examination work of our routine can not accurately check out the quality of platinum resistance thermometer sensor, PT100.
Summary of the invention
