Abstract
The utility model discloses a leakage-proof plate of electric power. The leakage-proof plate includes a stainless steel shell. The stainless steel shell is provided with a plurality of installation holes uniformly. The leakage-proof plate of electric power also includes a plurality of insulators arranged in the stainless steel shell, and inserting pins corresponding to the insulators one to one. Sealing adhesive layers are arranged on both inner side and outer side of the insulators. The stainless steel connects with the insulators fixedly by using sintering technique. The insulators also connect with corresponding inserting pins fixedly by using sintering technique. A sealing cover is fixed on one side of the stainless steel shell. One ends of the inserting pins protrude from the sealing cover. The leakage-proof plate of electric power in the utility model has a simple structure, low manufacturing cost and high performance. The leakage-proof plate of electric power in the utility model has a function of electromagnetic shielding. The leakage-proof plate of electric power in the utility model is used for circuit connections between electronic devices as well as electrical equipment of power equipment as well as sealing containers and power sources. The leakage-proof plate of electric power in the utility model connects with a sealing container or a piece of electrical equipment through a sealing gasket. By using the leakage-proof plate of electric power in the utility model, the gas tightness is good. And the sealing performance of the electrical equipment can meet the requirement of 1*10-4 Pa.cm3/S.
Description
Technical field
The utility model relates to a kind of electric power water-tight equipment, specifically, relates to a kind of electric power anti-leak plate.
Background technology
Along with the society, constant development of economy, the increasing of engineering construction complexity, the miniaturization of user's switching devices, non-maintaining, intelligentized require increasingly high.Under this background, cabinet type Cubicle Gas-Insulated Switchgear more and more is caused extensive concern.
Cabinet type Cubicle Gas-Insulated Switchgear is to adopt hypobaric SF
6Gas, N
2Gas or mist are as dielectric, with vacuum or SF
6Be arc-extinguishing medium; Medium pressure elements such as bus, circuit breaker, isolating switch are concentrated be enclosed in the casing; The modern insulation technology of integrated use, cut-off the new high-tech product that integrates Based Intelligent Control, protection, supervision, measurement, communication that technology, manufacturing technology, sensing technology, digital technology are produced, have that volume is little, in light weight, fail safe is good, reliability is high, can adapt to and advantage such as use under the severe environmental conditions.
In recent years; Gas-insulated switchgear has obtained promptly promoting and using in China; Particularly along with China's urban distribution network construction and switching devices such as transformation, track traffic and large industrial enterprise have proposed new requirements at the higher level such as miniaturization, intellectuality, non-maintaining, full operating mode, high-performance, high-quality inflation cabinet demand at home are more and more stronger.
All live parts of gas-insulated switchgear and switch all are sealed in the insulation gas filled electric power water-tight equipment, and the outlet of its cable insulating gas takes place easily leaks.In the described insulating gas, some gas is suffocating substance, and also some gas is not only poisonous, and has corrosivity.So, in case leaking of insulating gas taken place, just being easy to cause staff's anoxic, poisoning and suffocate, even can strong impulse and toxic action be arranged human body and respiratory system, this has also constituted the subject matter of electric power water-tight equipment aspect security protection.
Insulator is mounted between the conductor of different potentials or between conductor and the earth potential member, can withstand voltage and the insulation control of mechanical stress effect.Insulator is in order to increase creepage distance, to be processed by glass or pottery usually, can in overhead transmission line, playing support wire and prevent that electric current from returning the effect on ground.
Sintering is to change granular material into DB; To improve the performance of goods, be a traditional technical process, that is: powder or pressed compact are being lower than heating under the key component melting temperature; Make body of powder produce particle and cohere, produce intensity and cause densification and the process of crystallization again.People utilize this technology to produce pottery, powder metallurgy, refractory material, hyperthermal material etc. very early.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned defective, provide a kind of simple in structure, air-tightness good, electric power anti-leak plate with electromagnetic shielding action.
For addressing the above problem, the technical scheme that the utility model adopted is:
A kind of electric power anti-leak plate; Comprise stainless steel casing; Evenly be provided with several installing holes on the stainless steel casing; It is characterized in that: said electric power anti-leak plate also comprise several be located in the stainless steel casing insulator and with insulator contact pin one to one, the inside and outside both sides of insulator all are provided with sealant layer; Be fixedly connected through sintering process between stainless steel casing and the insulator, also be fixedly connected between insulator and the corresponding contact pin through sintering process; One side of stainless steel casing is fixed with sealing shroud, and an end of contact pin passes sealing shroud.
Owing to adopted technique scheme; Compared with prior art; The utility model is simple in structure, cost of manufacture is low, performance is high, have electromagnetic shielding action, is used for the electronic instrument, electric equipment of power equipment, airtight container and is connected with circuit between the power supply, is connected with sealing gasket with seal case, electric equipment; Air-tightness is good, can make the sealing property of power equipment reach 1 * 10
-4Pa.cm
3/ S requirement.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the A-A view of Fig. 1.
Among the figure: the 1-stainless steel casing; The 2-contact pin; The 3-sealant layer; The 4-installing hole; The 5-insulator; The 6-sealing shroud.
Embodiment
A kind of electric power anti-leak plate, like Fig. 1, shown in Figure 2, comprise stainless steel casing 1, several be located in the stainless steel casing 1 insulator 5 and with insulator 5 contact pin 2 one to one, the inside and outside both sides of insulator 5 all are provided with sealant layer 3.Evenly be provided with several installing holes 4 on the stainless steel casing 1.Be fixedly connected through sintering process between stainless steel casing 1 and the insulator 5, also be fixedly connected between insulator 5 and the corresponding contact pin 2 through sintering process.One side of stainless steel casing 1 is fixed with sealing shroud 6, and an end of contact pin 2 passes sealing shroud 6.
During use, earlier the cable inside and outside the electric power water-tight equipment is welded on the two ends of contact pin 2, then, with screw the anti-leak plate is fixed, is sealed on the electric power water-tight equipment getting final product.
