Abstract
The utility model discloses a nut tight-splicing type leakage prevention plate. The nut tight-splicing type leakage prevention plate is characterized by comprising a stainless steel case, a nut tight-splicing type convex disposed on an outer wall of the stainless steel case, a nut threadedly connected on the stainless steel case, a plurality of insulators disposed in the stainless steel case, contact pins in a one-to-one correspondence with the insulators, and sealing adhesive layers disposed on an inner side and an outer side of the insulators. The stainless steel case and the insulators are fixedly connected by a sintering technology, and the insulators and corresponding contact pins are also fixedly connected by the sintering technology. A seal ring is disposed between the nut tight-splicing type convex and the nut. The nut tight-splicing type leakage prevention plate is simple in structure, low in production cost, and is easy to produce and has good performance. The leakage prevention plate having an electromagnetic shielding effect can be used in circuit connection between electronic instruments or electrical equipment such as electric high-voltage switch devices, sealed containers, etc. and a power supply. The leakage prevention plate connects with a sealed box and electrical equipment by a sealing gasket using a nut tight-splicing fix method, so that air tightness is good, and sealing property of the electrical equipment can reach a requirement of 1x10<-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 nut and pieces together compact form 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, be easy to produce, air-tightness is good, nut with electromagnetic shielding action is pieced together compact form anti-leak plate.
For addressing the above problem, the technical scheme that the utility model adopted is:
A kind of nut is pieced together compact form anti-leak plate; It is characterized in that: comprise stainless steel casing, be located at that nut on the stainless steel casing outer wall is pieced together the compact form convex body, is threaded in nut on the stainless steel casing, 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 are respectively equipped 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.
Say further, be provided with sealing ring between said nut assembly compact form convex body and the nut.
Owing to adopted technique scheme; Compared with prior art; The utility model is simple in structure, be easy to produce, cost of manufacture is low, performance is high, have electromagnetic shielding action, is used for electronic instruments such as power high voltage switchgear, airtight container, electric equipment and is connected with circuit between the power supply, and the mode that adopts the nut assembly to fasten 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.

Embodiment
Embodiment:
A kind of nut is pieced together compact form anti-leak plate; Like Fig. 1, shown in Figure 2; Comprise stainless steel casing 6, be located at that nut on stainless steel casing 6 outer walls is pieced together compact form convex body 8, is threaded in nut 1 on the stainless steel casing 6, several be located in the stainless steel casing 6 insulator 4 and with insulator 4 contact pin 3 one to one, said nut is pieced together between compact form convex body 8 and the nut 1 and is provided with sealing ring 5.The inside and outside both sides of insulator 4 are respectively equipped with sealant layer 2,7.Be fixedly connected through sintering process between stainless steel casing 6 and the insulator 4, also be fixedly connected between insulator 4 and the corresponding contact pin 3 through sintering process.
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, through nut 1 the anti-leak plate is fixed, is sealed on the electric power water-tight equipment getting final product.
