Abstract
A 12kv resistance divider includes wire terminal, signal terminal, earthing terminal, ceramic wafer, resistance wire, and a green color protection layer covered by a black protection layer then rubber.
Description
Technical field
The present invention belongs to the electric power project engineering field, particularly relates to improved design of 12kV fixed sealing type resitstance voltage divider and the manufacturing used on a kind of intelligentized AC vacuum circuit-breaker.
Background technology
The 12kV AC vacuum circuit-breaker is an electromechanical integrated product, is widely used in electric power system 12kV and the indoor switchgear assembly of following electric pressure, and the intellectuality of breaker body, miniaturization are the developing direction of circuit breaker.Therefore design novel resitstance voltage divider summation current transformer and become the research and development emphasis of intelligent breaker with the integrated technology of circuit breaker, for the quality requirement of resitstance voltage divider also than higher.And 12kV AC vacuum circuit-breaker use at present is universal resitstance voltage divider product; its universal resitstance voltage divider product precision is low, stability is bad; and universal resitstance voltage divider product; only has the function that single Guan Heyu cut-offs; only be an actuator in the complete circuit, and circuit move various parameters and close, divide, protect command signal to rely on outside supporting component to provide.
Summary of the invention
The purpose of this invention is to provide a kind of 12kV fixed sealing type resitstance voltage divider, to overcome the shortcoming that present universal resitstance voltage divider product exists.
In order to realize that above-mentioned purpose technical scheme of the present invention is: 12kV fixed sealing type resitstance voltage divider, be made up of the green color protective layer 6 on 5 of resistance wire 5 on 4 of binding post 1, signal terminal 2, earth terminal 3, the ceramic substrate 4 of the inner bottom, the ceramic substrates of outside and that be connected with binding post 1, signal terminal 2 and earth terminal 3 and the resistance wires, it is characterized in that: the outer surface of described green color protective layer 6 also is provided with black color protective layer 7; The outer surface of described black color protective layer 7 also is provided with silastic-layer 8; It is RuO that described resistance wire 5 adopts ruthenium
2High temperature low-temperature coefficient resistance slurry is made; The diaphragm that described green color protective layer 6 employing boron zinc BPb glass are raw material is made; The black color diaphragm that described black color protective layer 7 employing boron zinc BPb glass are raw material is made.
Adopt that the present invention of above-mentioned measure has that body is long-pending little, low in energy consumption, precision is high, the good stability of resistor, dynamically good, bandwidth of big, the anti-electromagnetic interference performance of span and no ferromagnetic full advantage.
Description of drawings
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Accompanying drawing 1 is a three-dimensional broken section structure chart of the present invention.
Embodiment
With reference to the accompanying drawings 1, Fig. 1 is a three-dimensional broken section structure chart of the present invention.Can find out the structure that the present invention is concrete from figure, it is made up of the green color protective layer 6 on 5 of resistance wire 5 on 4 of binding post 1, signal terminal 2, earth terminal 3, the ceramic substrate 4 of the inner bottom, the ceramic substrates of outside and that be connected with earth terminal with binding post 1, signal terminal 2 and the resistance wires, and the outer surface of this green color protective layer 6 also is provided with black color protective layer 7; The outer surface that should deceive color protective layer 7 also is provided with silastic-layer 8, thereby improves the stability of resitstance voltage divider precision and use.
Specific practice of the present invention is: well cutting ceramic substrate at first; on ceramic substrate 4, make printed resistor silk 5 and make binding post 1, signal terminal 2, earth terminal 3; and with 800 ℃ of sintering; print green color protective layer 6 at resistive surface again; the black color protective layer 7 of seal again after the laser resistor trimming, and with 600 ℃ of high temperature sinterings.To weld 12kVAC binding post 1,5VAC signal terminal 2, earth terminal 3 with high temperature solder materials behind the divider resistance high temperature ageing.Adopt APG technology parcel silastic-layer 8 at last.For solving high-tension creepage and safe insulation, adopted unique silicon rubber numerical control injection-molding moulding process, resitstance voltage divider parcel with ceramic substrate, the high-low pressure leading-out terminal adopts high temperature wire, and be enclosed in the circuit breaker polar admittedly with epoxy resin, resitstance voltage divider and air are completely cut off to come, thereby the various unfavorable factors in the air ambient have been avoided, the environmental suitability of product is greatly improved, and, make the miniaturization of product become possibility because the dielectric strength of epoxy resin is much higher than air dielectric.This transducer has all been broken through the current/voltage transducer of traditional cored structure from the principle to the structure, have that volume is little, precision is high, big, the anti-electromagnetic interference performance of dynamic span is good, an advantage such as bandwidth and iron-free magnetic saturation.This 12kV fixed sealing type resitstance voltage divider volume is little, power consumption is lower than 2 watts, temperature coefficient and is lower than 100ppm, can directly be cemented in the pole of 12kV AC circuit breaker.
It is RuO that resistance wire 5 of the present invention adopts ruthenium
2High temperature low-temperature coefficient resistance slurry is made.The diaphragm that these green color protective layer 6 employing boron zinc BPb glass are raw material is made.The black color diaphragm that these black color protective layer 7 employing boron zinc BPb glass are raw material is made.
