Abstract
The utility model provides an intelligent indoor high-voltage vacuum circuit breaker, which comprises an actuator, a solid-sealed polar pole, a chassis, contact arms and tulip contacts. The actuator is arranged on the chassis; the solid-sealed polar pole is fixed on the upper end surface at one side of the actuator; the solid-sealed polar pole is fixedly connected with one end of each contact arm; the other end of the contact arm is fixedly connected with each tulip contact; and a temperature sensor is arranged at the place, near the tulip contact, on the contact arm. As the temperature sensor is arranged on the contact arm of the circuit breaker, temperature of the tulip contact of the circuit breaker can be monitored in real time, safety accidents caused by temperature rising of the circuit breaker in actual operation can be greatly reduced, and a good prevention role can be played.
Description
Technical field
The utility model belongs to high-voltage switch gear technical field, is specifically related to a kind of intelligent indoor high-voltage vacuum circuit breaker, can support the use 50(60 in 12kV and 35kV electrical power trans mission/distribution system) ring main unit or the power distribution cabinet of Hz.
Background technology
The important task that primary cut-out is being undertaken the protections such as the overload, short circuit of power equipment and controlled in high-voltage power supply and distribution system.At present, in the indoor distribution system of 6～35kV, take KYN28A-12 and KYN61-40.5 switch cubicle (armored type withdraw-type AC metal closed switch cabinet) is main flow cabinet type, thereby handcart-type high-voltage vacuum circuit breaker VS1-12 matching used with it and ZN85-40.5 series are also popularized by large area.Widely used handcart-type high-voltage vacuum circuit breaker VS1-12 and ZN85-40.5 series in current domestic distribution system, mainly there is following defect: the one, handcart type breaker is when joining cabinet, because fixed contact is installed on contact box inside, when handcart operates in service position, the engagement size of the dynamic/static contact artificially measurement data of subjectivity guarantees, and such method of testing does not often possess generality, and in switch shape dimension measurement process, require operating personnel's operative skill and peopleware quite high; The 2nd, circuit breaker is in actual motion, due to the otherness of environment for use factor, dynamic and static contact meshes not in place at the scene, and loop resistance increases, when logical super-high-current, conductive contact surface temperature raises, and aggravation surface oxidation, further increases contact resistance, form vicious circle, after developing into certain phase, can cause solid insulation deteriorated, insulation fault occurs, destroy the safe and reliable of power supply; The 3rd, due to dynamic/static contact, the loose contact of connector contact part, form local overheating, thereby cause ageing of insulation, cause circuit breaker to puncture over the ground, this is also one of principal mode of circuit breaker failure.Above-mentioned defect, has restricted further developing of circuit breaker, is therefore necessary to propose to improve.
Utility model content
The technical problem that the utility model solves: a kind of intelligent indoor high-voltage vacuum circuit breaker is provided, by the position near Mume flower contact on contact arm, semiconductor fiber temperature sensor is installed, make circuit breaker can carry out intelligent temperature measurement when service position, simultaneously can carry out Real-Time Monitoring visual and that report to the police to the Mume flower contact temperature of circuit breaker, integrate intelligent, integrated, fail safe and hommization.
The technical solution adopted in the utility model: intelligent indoor high-voltage vacuum circuit breaker, there is operating mechanism, pole, chassis vehicle, contact arm and Mume flower contact, described operating mechanism is arranged on chassis vehicle, described pole is fixed on operating mechanism one side upper surface, described pole is fixedly connected with contact arm one end, the described contact arm other end is fixedly connected with Mume flower contact, and the position near Mume flower contact on described contact arm is provided with temperature sensor.

Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing 1, a kind of embodiment of the present utility model is described.
Intelligent indoor high-voltage vacuum circuit breaker, there is operating mechanism 1, pole 2, chassis vehicle 3, contact arm 4 and Mume flower contact 5, described operating mechanism 1 is arranged on chassis vehicle 3, described pole 2 is fixed on operating mechanism 1 one side upper surfaces, described pole 2 is fixedly connected with contact arm 4 one end, described contact arm 4 other ends are fixedly connected with Mume flower contact 5, and the position near Mume flower contact 5 on described contact arm 4 is provided with temperature sensor 6, underlying semiconductor fibre optic temperature sensor.Meanwhile, pole 2 optical fiber built-ins, described optical fiber one end is connected with temperature sensor 6, and the optical fiber other end is directly connected with secondary plug.The cabinet of described circuit breaker is provided with Mume flower contact 5 temperature is carried out to LCDs visual and warning Real-Time Monitoring.
Operation principle: by being arranged near the fibre optic temperature sensor of Mume flower contact 5, the variations in temperature of Mume flower contact 5 is transmitted through the fiber to optical branching device, pass through optical-electrical converter, light signal is converted to the signal of telecommunication, by signal, amplify again, finally by backstage microcomputer, carry out data processing, by LCDs, export data.It should be noted that, semiconductor fiber temperature sensor is to utilize the absorption spectrum variation with temperature of semi-conducting material to realize, and when temperature increases, absorbing wavelength can move to long wavelength's direction.When semi-conductive absorption coefficient becomes after certain relation with reflection coefficient, the light intensity of supposing incident light is P, and when reflectivity is r, catoptrical light intensity is R=Pr, and when incident light is certain, it is large that temperature rising reflectivity becomes, and reflective light intensity increases; Temperature declines, and reflectivity diminishes, and reflective light intensity diminishes.
In sum, by the contact arm of circuit breaker, temperature measuring equipment being set, Mume flower contact 5 temperature of circuit breaker are carried out to Real-Time Monitoring, make circuit breaker in actual motion because security incident that temperature rise causes greatly reduces, played good prevention effect.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, and the equivalence of being done with content described in the utility model claim therefore all changes, within all should being included in the utility model claim scope.
