Device, the apparatus structure is simple, obvious drying effect, easy to carry, is highly suitable for Outdoor Trusses For Transformer Substation and carries out capacitor voltage
The drying of mutual inductor secondary terminals achievees the purpose that efficiently to lighten the burden convenient for carrying out the experiment of capacitance type potential transformer.
Realizing the technical solution of the utility model aim is：
A kind of drying device for capacitance type potential transformer secondary terminals, including groove type device body, Yi Jiyu
The compatible lid of groove type device body；
Heating device is equipped in the groove type device body, the bottom of ontology is fixed with fan and control switchs；
The lid is equipped with heat emission hole and rectangular recess, is equipped with magnet in rectangular recess, magnet can be in rectangle
It is moved in groove；
The heating device connects a Temperature Humidity Sensor；
The heating device, fan are electrically connected with control switch by power cord respectively；
The drying device is fixedly connected by magnet with capacitance type potential transformer secondary terminals, is realized to secondary terminals
Rapid draing.
Heat emission hole on the lid is oppositely arranged with heating device, and air outlet of the heat emission hole as fan cooling, is scattered
Heat and dehumidifying provide channel.
The heating device is the prior art, and electrically heated rod etc. can be used, voltage transformer secondary terminal is dried.
The fan is the prior art, and voltage transformer secondary terminal can be blowed, and moisture and moisture are driven away, from
And achieve the purpose that dehumidifying, drying.
The control switch is the prior art, interior to be equipped with Temperature Humidity Sensor, can measure the temperature inside drying device
Degree and humidity, and shown by its display screen, it is conveniently operated.
The control switch is the core control element of drying device, controls the operating mode of drying device, controls simultaneously
Sensor in it can measure the temperature and humidity of voltage transformer secondary terminal, to detect the drying of drying device
Degree.
The advantages of the utility model drying device：
1, versatile
The drying device is fixedly connected by magnet with capacitance type potential transformer secondary terminals, and magnet is removable, mobile
Magnet can be such that the two is fixedly connected to position corresponding with secondary terminals, therefore the capacitor voltage for being applicable in all models is mutual
The drying of sensor secondary terminals, and it is easy to carry.
2, manpower is saved
In the past when substation carries out the drying of capacitance type potential transformer secondary terminals, people's staircase, a people are needed
With hair dryer is used, workload is larger, and labor intensity is higher.Using the utility model drying device, opened using intelligentized control method
It closes and replaces human hand dehumidifying, dry, it is both time saving and energy saving, it reduces labor intensity, improves working efficiency, in turn ensure dehumidifying, drying
Effect.
