The running state of the temperature rise fault point is dynamically tracked and monitored, so that accidents can be prevented and eradicated, and an important decision basis is provided for safe and reliable analysis and scientific scheduling of the power system. The passive wireless temperature measurement is an ideal monitoring mode applicable to various different temperature measurement environments of power equipment.
The existing passive wireless temperature measuring device applied to the power equipment contact discloses a passive wireless temperature sensor of a 10kV circuit breaker contact as Chinese patent No. 201721039325.6, which comprises a temperature measuring module, a Teflon feeder line and an antenna, wherein the temperature measuring module and the antenna are connected through the Teflon feeder line, the bottom of the temperature measuring module is provided with an induction copper sheet, the induction copper sheet is attached to a tangent plane platform of the 10kV circuit breaker contact, the Teflon feeder line is integrally positioned in the 10kV circuit breaker contact, the 10kV circuit breaker contact is provided with a heat dissipation hole, one end of the Teflon feeder line is connected with the temperature measuring module, and the other end of the Teflon feeder line penetrates through the heat dissipation hole and is connected with the antenna. The disadvantages are that: the antenna is exposed on the contact, the antenna and the feeder connected with the antenna are easily damaged by the high temperature of the contact, the structure is complex, and the installation is inconvenient.
Disclosure of Invention
In order to overcome the passive wireless temperature measuring device of current use on the power equipment contact and have the feeder that exposes antenna and connection to be damaged by the high temperature of contact easily, and the structure is complicated, the inconvenient scheduling problem of installation, the utility model aims at providing a passive wireless temperature measuring device of moving contact of modified power equipment can overcome prior art's defect.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a passive wireless temperature measuring device of power equipment's moving contact, sets up inside the cubical switchboard which characterized in that: the RFID temperature measurement device comprises an RFID temperature measurement label arranged on a moving contact and a receiving and transmitting antenna arranged on the inner side surface of a switch cabinet, wherein the RFID temperature measurement label is fixed on a moving contact arm of the moving contact through a heat conduction copper sheet, the moving contact arm and the outer surface of the RFID temperature measurement label are covered with an epoxy resin insulating layer, and the RFID temperature measurement label comprises a miniature intelligent temperature sensor and a passive ultrahigh frequency RFID chip.
According to the technical scheme, the RFID temperature measurement tag can be embedded into the movable contact arm, and the RFID temperature measurement tag and the movable contact arm are vulcanized to generate the epoxy resin insulating layer.
The receiving and transmitting antenna can be electrically connected with a reader-writer for background information processing.
According to the technical scheme, the reader-writer can be arranged in a secondary chamber in a switch cabinet.
The utility model has the advantages that: because including installing the RFID temperature measurement label on the moving contact and installing the antenna in the inside side of cubical switchboard, the RFID temperature measurement label passes through the heat conduction copper sheet and fixes on the movable contact arm of moving contact, the movable contact arm with RFID temperature measurement label surface covers the epoxy insulating layer, the RFID temperature measurement label includes miniature intelligent temperature sensor and passive hyperfrequency RFID chip, and receiving and dispatching antenna does not establish on the moving contact like this, is wireless connection between RFID temperature measurement label and the receiving and dispatching antenna, so effectively avoided antenna and feeder easily by the problem of the high temperature damage of contact, and temperature measuring device simple structure, the installation of being convenient for, the insulating properties in the outside is good.
The invention is further described with reference to the following figures and examples.
