Description
Technical field
This utility model relates to a kind of device for detecting temperature, particularly to a kind of high voltage isolator device for detecting temperature.
Background technology
In high voltage substation, open isolating switch is placed on outdoor, after repeatedly cut-offfing, impact due to factors such as vibration, mechanical deformation, environment, contact resistance between contact is caused to increase, in turn resulting in the huge increasing of caloric value, if taken no action to, contact abnormal heating continues, eventually cause isolation switch to burn, even result in the danger expanding power grid accident.Traditional method is to be done D.C. resistance test when having a power failure by testing crew, or is in operation and is carried infrared measurement of temperature equipment by staff, keeps apart pass to every and detects.
Existing technology is to utilize infrared temperature-test technology that isolation switch contact is carried out real time on-line monitoring.Infrared measurement of temperature equipment is placed on isolation switch Steel Structure.Insulation column porcelain knob for acting the effect supporting and insulating to chopper switch.Owing to chopper switch two terminates high-voltage conducting wires, therefore whole chopper switch band high voltage.When the contact of chopper switch is bad, contact can generate heat, can outwards discharge infrared ray simultaneously, temperature is more high, the infra-red intensity of release is more big, the infrared measurement of temperature equipment being placed on lower end judges the size of contact temperature by the ultrared power received, and by wireless background monitoring main frame that temperature value is sent to.Infrared measurement of temperature monitoring device has the disadvantage in that 1) need low pressure inlet wire to power, therefore additionally to arrange and add the time of equipment cost and construction by power line；2) contact position of high voltage isolator is all significantly high, it is difficult to judge the contact whether infrared temperature measuring head targeted by isolation switch, simultaneously high voltage isolator is mounted in open air, blows, touches by mistake, the factor such as switch machine vibration easily causes the skew of infrared temperature measuring head position；3) accuracy of infrared measurement of temperature is affected very big by outdoor different weather, additionally, time one long dust can drop on infrared temperature measuring head, hinders ultrared transmission, causes the error of measurement.
Summary of the invention
In order to solve above-mentioned technical problem, this utility model provide a kind of power without power supply, certainty of measurement is high, the high voltage isolator device for detecting temperature of stable performance.
This utility model solves the technical scheme of the problems referred to above: a kind of high voltage isolator device for detecting temperature, including politef shell, miniature inductive loop, electrical energy conversion circuit, signal processing circuit, antenna, politef shell is arranged on chopper switch contact by installing hole, it is provided with miniature inductive loop in politef shell, the output of miniature inductive loop connects electrical energy conversion circuit, the output of electrical energy conversion circuit connects the power supply of signal processing circuit, open a hole at politef outer casing bottom and critesistor is installed, critesistor directly contacts with chopper switch contact, the output of critesistor is connected with signal processing circuit, filling epoxy resin in politef shell inner cavity body.
The beneficial effects of the utility model are in that: this utility model adopts miniature inductive loop to obtain electric energy, it is not necessary to external power supply is powered；Whole temperature measuring equipment adopts the parcel insulation of politef shell, is directly installed on high voltage isolation switch contact, and simple installation, debugging is convenient；Adopting contact temperature-measuring, temperature measuring equipment directly contacts with high voltage isolation switch contact, and certainty of measurement is high, not by the impact of environmental factors.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As it is shown in figure 1, this utility model adopts politef shell 5 parcel insulation, shell 5 is arranged on chopper switch contact 7 by installing hole 8.Miniature inductive loop 1 it is provided with in shell 5, electromotive force is induced by the alternating magnetic field near chopper switch contact 7 by miniature inductive loop 1, the electromotive force of sensing is transferred to electrical energy conversion circuit 2 by miniature inductive loop 1, faint electromotive force is passed through full-wave rectification bridge by electrical energy conversion circuit 2, AC energy is changed into direct current energy, and it is stored in storage capacitor, begin to when the electric energy in storage capacitor reaches a certain amount of power to signal processing circuit 3 below.Bottom politef shell 5, open a hole critesistor 6 is installed so that it is directly contact with chopper switch contact 7.Critesistor 6 is wired in signal processing circuit 3, and the temperature value recorded is sent by signal processing circuit 3 by antenna 4.In shell 5 inner chamber body, filling epoxy resin carries out insulation protection, it is prevented that components and parts are punctured by high-voltage switch switch contact 7.
This utility model is owing to adopting self-powered mode and wireless data transmission mode, it is not necessary to circumscripted power line and data telecommunication line, and therefore in-site installation is without wiring, installs simple, and the engineering time is short；Whole temperature measuring equipment adopts the parcel insulation of politef shell, it is possible to being directly installed on high voltage isolation switch contact, temperature measurement location is fixed, simple installation, and debugging is convenient；Owing to adopting contact temperature-measuring, temperature measuring equipment directly contacts with high voltage isolation switch contact, and certainty of measurement is high, not by the impact of environmental factors.
