China's utility model patent ZL88221154.4 number and ZL89218524.4 disclose its name respectively and have been called " porcelain insulator electric capacity high voltage display " and " pillar porcelain insulator formula high voltage display device ", because their insulator is to adopt ceramic body, in ceramic body, use material hybrid package capacitance bodies such as cement, bonding agent.Therefore exist in transportation, the assembling process and can produce uncertain sudden fracture during running status, and dielectric strength is low, electric property is poor and bending strength does not reach a series of outstanding shortcomings such as national standard of 8kN, in addition, because the electric capacity that adopts two copper sheets to form, electric capacity is little, below the general 20PF, above-mentioned method seldom is used at present.
High-voltage strut insulator sensor adopts the high-voltage strut insulator of capacitance core bar type to carry out collection, demonstration or the control of an electric signal mostly at present.Yet mainly there are the following problems to adopt the high-voltage strut insulator of capacitance core bar type: the electric capacity plug is connected under the high voltage as time goes by for a long time, and the electric property of electric capacity plug also can progressively successively decrease even damage, and therefore, has the problem in serviceable life.Because an end of electric capacity plug directly is connected with a high-tension electricity; to show that primary circuit has or not electriferous state; under quality problems such as the technology influence of electric capacity plug; the electric capacity plug causes the first breakdown phenomenon easily; and can cause support insulator to puncture after the first breakdown of electric capacity plug; thereby cause the damage of high voltage display device, even the security of operation of crisis high-tension switch gear and electric power operation personnel's life security.In recent years, some power supply departments, the high-voltage strut insulator breakdown of a lot of capacitance core bar types takes place after, cause major accidents such as high-tension switch gear blast.
The utility model content
The purpose of this invention is to provide induction-type high-voltage support insulator sensor, this sensor has good electric property, and electric capacity is big, long service life, and be difficult for puncturing, safe and reliable to operation.
The utility model induction-type high-voltage support insulator sensor, comprise: the outside is provided with insulator, upper flange, lower flange, the signal end of the full skirt of several big or small alternate poured with epoxy resin, its feature is embedded with the pole plate group in the middle and lower part that is positioned at insulator, the pole plate group is at least three pole plates composition of being separated by, the pole plate of pole plate group is cross-linked, be connected with signal end with lower flange respectively, pole plate group and upper flange be different cavity in insulator respectively, and pole plate group and upper flange do not communicate.
The utility model induction-type high-voltage support insulator sensor, except that recited above, the plate material of pole plate group is a copper coin.
The utility model induction-type high-voltage support insulator sensor, except that recited above, the plate face of the pole plate of pole plate group is distributed with some holes.
The beneficial effects of the utility model are: because the utilization induction type principle of sensor is gathered an electric signal, directly do not contact with a high-tension electricity, capacitance core bar type product can produce the dangerous reliable defective of first breakdown thereby solved in the past; Sensor capacitance adopts three pole plate groups that constitute with top crown, and special manufacture craft, makes the electric capacity of sensor select capacitance arbitrarily for use according to the quantity of polar plate of pole plate group, to satisfy the service condition of various high-voltage charge display devices; The utility model does not directly contact with a high-tension electricity, can make appliance electronic component reduce loss and the serviceable life that increases high-voltage charge display device, good electric property.Because insulator adopts epoxide resin vacuum pouring technology mode, with electrician trade in the past the ceramic-like of traditional usefulness compare, have bending strength height in light weight, mechanical, combine close and firm with hardware, be difficult for fragmentation, cracking, distortion, seepage in transportation, assembling process and under the running status, has high strength, characteristics such as anti-electric arc ability is strong, and partial discharge quantity is little have very high reliability under severe contamination or even exceedingly odious condition.Induction-type high-voltage support insulator sensor of the present utility model, can be according to customer requirements, on surface structure, can be made into differing heights and full skirt style, can with the supporting use of the charged display device of the series high voltage of prompting-type or forced blocking, also can with supporting uses such as all kinds of high-tension switch cabinets, disconnector, grounding switch.
