The utility model discloses advance the benzvalene form insulator with temperature sensor is pre -buried, do not have sealed problem, need not change the gaseous internal electric field structure of GIS, can not influence that its is insulating to utilizing benzvalene form insulator conduction temperature, direct contact to measure, not influenced by other factors, it is accurate to measure, temperature sensor damages, does not need to have a power failure, can dismantle temperature sensor on line, the temperature data who gathers passes through wireless transmitting and gives the monitoring backstage, and the scene does not need wiring, simple installation.
Description
Technical field
This utility model relates to a kind of temperature sensor, particularly to a kind of GIS busbar joint device for detecting temperature.
Background technology
Gas insulation metal seal combined electrical apparatus (GIS device) galvanic circle comprises a large amount of plug-in type contact, as first-class in the chopper under bus junction point, closure state and switch touching.Owing to there is gross error when build-up tolerance and construction in installation process, there is the hidden danger such as docking is concentric, insertion depth is not enough in some electric terminal, owing to the degeneration of joint contact performance causes contact resistance to increase and causes contact overheating in equipment running process, cause busbar joint to burn time serious and cause short circuit accident.This kind of GIS joint Superheated steam drier occurrence frequency presents ascendant trend.
The infrared temperature-test technology that current GIS device mainly adopts.Opening a monitoring holes on GIS housing, installed on the cover board by infrared temperature sensor, its probe is through cover plate, and processes with cover plate incoming seal, and installation infrared optical filter before probe, for collecting the infrared ray that measured point on bus radiates.This monitoring there is the problem that 1) GIS air-tightness problem.Need on GIS, open a monitoring holes, between cover plate and monitoring holes, all potential between infrared sensor and cover plate gas leakage point；2.) owing to insulation needs, internal cleannes are required extremely harsh by GIS, and bus is all burnishing surface, and therefore adstante febre is very faint to extraradial infrared ray；3) infrared sensor is once damage, it is necessary to having a power failure after being drained by the SF6 gas in GIS device, unload lower cover 4 more emat sensor, power off time is long, and economic loss is big；4.) SF6 gas is very strong to infrared ray absorption ability, and the bus of the GIS of different model is different with the distance of housing, and the intensity that the infrared ray that same temperature gives off arrives sensor is different, and therefore bus temperature certainty of measurement is very low.
Summary of the invention
In order to solve above-mentioned technical problem, this utility model provides the GIS busbar joint device for detecting temperature that a kind of certainty of measurement is high, easy to maintenance.
This utility model solves the technical scheme of the problems referred to above: include disc insulator, disc insulator is screwed and is arranged on GIS shell, disc insulator has a hole, temperature sensor is placed in hole, temperature sensor is put and is connected with processes temperature signal circuit by data wire, and the outfan of processes temperature signal circuit is connected with antenna.
The beneficial effects of the utility model are in that:
Temperature sensor is nuzzled in disc insulator by this utility model in advance, is absent from sealing problem, it is not necessary to change GIS gas interior electric field structure, without influence on its insulation, and utilize disc insulator transition temperature, direct contact measurement, do not affected by other factors, measure accurately；Temperature sensor damages, it is not necessary to have a power failure, and can temperature sensor be dismantled online；The temperature data gathered gives monitoring backstage by wireless transmit, and scene need not connect up, simple installation.
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 shown in Figure 1.This utility model includes disc insulator 4, and busbar joint 2 is by vacuum pouring on disc insulator 4, and disc insulator 4 is arranged on GIS shell by fixed screw, and bus 3 is plugged in busbar joint 2.Disc insulator 4 is opened a hole 6 enter pre-buried for temperature sensor 5.When bus 3 and busbar joint 2 generate heat due to loose contact, heat will be conducted to disc insulator 4, the temperature of disc insulator 4 is measured by temperature sensor 5, and data are transferred to processes temperature signal circuit 9 are processed by data wire 7, the data of process are sent by processes temperature signal circuit 9 by antenna 10, and processes temperature signal circuit 9 is powered by battery 8.If temperature sensor 5 damages, as long as politef shell 11 is taken off, temperature sensor 5 is taken out from hole 6, then injects new sensor, it is not necessary to have a power failure and change.
Owing to temperature sensor is to be embedded in disc insulator when dispatching from the factory in this utility model, it is not necessary at GIS opening in shell, be absent from sealing problem；Need not change making in GIS device cavity, thus without changing its Electric Field Distribution, without influence on the dielectric strength of equipment；Temperature sensor is once damage, it is not necessary to being had a power failure by GIS, changing as long as temperature sensor being taken out from disc insulator, without economic loss；Owing to being utilize disc insulator conductive busbars connector temperature, direct contact measurement, do not affected by other factors, therefore measure accurately.
