Abstract
The invention relates to a fuse insulating cylinder of a sulfur hexafluoride switch cabinet. The fuse insulating cylinder comprises an insulating cylinder main body and two lead-out wires. Besides, the fuse insulating cylinder is characterized in that: the insulating cylinder main body and the two lead-out wires are integrated into a unibody; and the lead-out wires are at an outboard and a top of the insulating cylinder main body. According to the invention, the two lead-out wires and the insulating cylinder main body are integrated into a unibody. Besides, the fuse insulating cylinder has a simple structure; and there is no need for assembling; therefore, production efficiency and precision can be substantially improved; and a possible air leakage problem can be eliminated.
Description
Technical field
The present invention relates to a kind of electric power system High-Voltage Insulation equipment, specifically a kind of fuse insulating cylinder of sulphur hexafloride circuit breaker cabinet.
Technical background
The fuse insulating cylinder is the main insulating part in the sulphur hexafloride circuit breaker cabinet; Also be the main bearer element that realizes fuse and switch cabinet inner high voltage voltage transformer overcurrent protection, present sulphur hexafloride circuit breaker cabinet wants cube little because of design reasons; So do not have enough spaces and the fuse of method placement reliably in the inflation cabinet; Thereby can't carry out effective overcurrent protection to high voltage potential transformer, promptly lack necessary electic protection element, reasons such as system and equipment fault appear in this type disappearance easily makes winding of high voltage potential transformer the overcurrent phenomenon occur; Winding of instrument transformer can occur and burn phenomenon; To make the whole sulphur hexafloride circuit breaker cabinet phenomenon of blasting when serious, cause power outage, jeopardize personal device security.In order to solve this technical problem; Further improve sulphur hexafloride circuit breaker cabinet and electrical design; Need the fuse insulating cylinder of a kind of special use of design, inner high voltage potential transformer is carried out effective overcurrent protection, avoid occurring accidents such as serious power failure, device damage.
Traditional sulphur hexafloride circuit breaker cabinet fuse insulating cylinder is assembled by some parts, and parts are many, assembles loaded down with trivial detailsly, and precision is difficult to guarantee; Owing to adopt the sealing ring sealing, possibly there is the improper problem that causes the gas leakage of fuse insulating cylinder of assembling.
Summary of the invention
The objective of the invention is in order to solve existing fuse insulating cylinder parts manyly, assemble loaded down with trivial detailsly, can't guarantee precision and the problem that possibly have gas leakage.
The technical scheme that the present invention adopts is following:
A kind of sulphur hexafloride circuit breaker cabinet fuse insulating cylinder comprises insulating cylinder body and two and draws lead, and it is characterized in that: it is one-body molded that insulating cylinder body and two is drawn lead, draws the outside and top that lead is positioned at the insulating cylinder body.
The invention has the beneficial effects as follows: draw lead and this body by integral forming of insulating cylinder with two, make the fuse insulating cylinder simple in structure, need not assembling, improved production efficiency and precision greatly, and eliminated possible gas leakage problem.
Description of drawings
Accompanying drawing is the structural representation of embodiment of the present invention.
Specific embodiments
As shown in the figure, during use, in the cavity with fusible the insulating cylinder body 1 of packing into of fuse, install the seal that is complementary with insulating cylinder body 1 then, fusible is sealed in the cavity that insulating cylinder body 1 and seal surround; The joint of drawing lead 2 then can be connected with the miscellaneous part of sulphur hexafloride circuit breaker cabinet.
Claims (1)
