Abstract
The utility model discloses a power loop-network cabinet sulfur hexafluoride anti-leakage connector which consists of a socket and a plug which are integrated by a connecting cap through a collar; the socket comprises an outer shell which subsequently consists of an outer connector, a connecting nut and a disk lug which are connected together; the outer shell is provided with a sintered part and an insulating bush; the insulating bush is arranged in the outer connector by an O-shaped ring; the sintered part consists of a plate which can be cut, a contact pin and a glass insulator; the periphery of the contact pint is provided with a contact pin gasket; the plug consists of a shell, a cable transition cover and a cable gland cover which are subsequently connected; the cable gland cover is fixedly arranged on the cable transition cover by a cable locking cap; the shell is provided with a jack cover plate with a crown spring jack; the peripheral of the crown spring jack is provided with a jack insulator. The connector solves the technical problems of poor anti-leakage performance and high price of the prior art; because the sealing and insulating performance is good, the protection level of the whole connector reaches Level IP67, so the problem of sulfur hexafluoride leakage is effectively prevented.
Description
Technical field
The utility model belongs to the electric power facility technical field, relates to a kind of electric power ring main unit sulphur hexafluoride anti-leak connector.
Background technology
From the later stage nineties 20th century, electric power system gradually adopts looped network tie lines and multiloop distribution pattern, and optimizes cable distrbution network structure, needs a large amount of ring main units (being the multiloop ring network power supply unit of sulfur hexafluoride gas-insulating).Though sulfur hexafluoride gas has irreplaceable effect as dielectric, but undeniable it have certain side effect: 1. the proportion of sulphur hexafluoride gas is 5 times of air, often accumulate near the ground, not easily dilutable and diffusion, it is a kind of suffocating substance, break down and cause staff's anoxic easily when leaking, poisoning suffocates; Can decomposite when 2. sulfur hexafluoride gas produces corona discharge in electric field and fluoridize sulfurous acid, fluoridize sulfuric acid, ten fluoridize nearly ten kinds of gases such as two sulphur, sulfur dioxide, sulfur fluoride, hydrofluoric acid.These fluorine, sulfide gas are not only poisonous, and much also are corrosive, and human body and respiratory system are had strong impulse and toxic action.For preventing that sulfur hexafluoride gas from leaking from the cable outlet of ring main unit, at present, normally be circuit and the installation of the circuit junction outside tank body sulphur hexafluoride anti-leak connector in the ring main unit tank body.But the sulphur hexafluoride anti-leak connector of prior art has anti-leak performance difference and expensive technical problem.
Summary of the invention
The purpose of this utility model is to solve prior art anti-leak performance difference and expensive technical problem, provides a kind of electric power ring main unit sulphur hexafluoride anti-leak connector with high-performance, low price, to overcome the deficiencies in the prior art.
To achieve these goals, the utility model electric power ring main unit sulphur hexafluoride anti-leak connector, form by socket and plug, socket and plug are connected as a single entity by collar by attachment cap, its main points be said socket it comprise the shell that is formed by connecting by coupling, attaching nut and disk convex body successively, establish sintered part and insulating case in the said shell, insulating case is installed in the coupling by O type circle, said sintered part forms by cutting down plate, contact pin and glass insulator sintering under the high temperature about 1000 ℃, reaches leak rate≤10 of gas
-9Pacm
3The purpose of/s, the periphery of contact pin is provided with the contact pin sealing gasket; Said plug is formed by connecting by housing, cable transition cover and cable gland successively, cable gland is fixedly mounted on the cable transition cover by the cable locking cap, be provided with the jack cover plate of band hat spring socket in the said housing, the periphery of hat spring socket is provided with the jack insulator.
Be provided with the aluminium clamping pad between said cable locking cap and the cable gland.
Said housing cooperates with the jack cover plate by back-up ring.
The flexible connection position of said parts is respectively equipped with O type circle.
The utility model reasonable in design, make simply, solved prior art anti-leak performance difference and expensive technical problem, during use, the contact pin on the socket is connected with circuit in the ring main unit tank body, the jack on the plug is connected with tank body circuit outward.Tighten attachment cap plug, socket are closely cooperated, circuit is connected together, owing to its sealing, good insulation preformance, the degree of protection of whole connector reaches the IP67 level, has prevented the problem that sulphur hexafluoride leaks effectively.
