Abstract
The utility model relates to a metal-enclosed ring network switchgear which has compact structure, flexible operation, safety, reliability and convenient installation, and can be modified according to the needs to be suitable for small secondary substation, industrial and mining enterprises, wind power generation stations and other places. The metal-enclosed ring network switchgear is characterized in that a load switch with a shell poured by epoxy resin is positioned between an upper unit and a lower unit, and a busbar array is positioned in a busbar chamber; an actuating mechanism, an interlocking device and a low voltage chamber are simultaneously positioned in the upper unit, and an arrester and voltage and current transformers which are connected with each other through cables are positioned in the lower part. The utility model has the advantages of compact structure, flexible operation, safety, reliability, convenient installation and modification, and strong universality.
Description
Technical field
The utility model relates to a kind of metal enclosed looped network switch apparatus, is mainly used in occasions such as city neighborhood is joined, compact secondary, switching station, industrial and mining enterprises, market, subway, airport, wind power generation, belongs to power equipment and makes the field.
Background technology
At present general metal enclosed looped network switch apparatus is because layout is unreasonable, not only maintenance difficulty, and lack enough safety guarantee and safety measure, both be unfavorable for the safe operation of equipment and maintenance fast, also can't realize the quick assembling and the debugging of equipment, and lack operability.
Summary of the invention
Purpose of design: avoid the weak point in the background technology.Design a kind of flexible operation, the safe and reliable and metal enclosed looped network switch apparatus that can reequip.
Design: in order to realize above-mentioned purpose of design.1, cabinet top is bus-bar room, on-load switch chamber, operating mechanism and low-pressure chamber and the separated design in cable vault by steel diaphragm and cabinet bottom, is one of feature of the present utility model.The purpose of doing like this is: can be safely, easily to being loaded on top--the device in-bus-bar room, on-load switch chamber, operating mechanism and the low-pressure chamber overhauls and transforms, and replaceable whole top.2, the shell of on-load switch be poured with epoxy resin form and in be filled with the design of sulfur hexafluoride gas, be the utility model design feature two.The purpose of doing like this is: make on-load switch have good insulation performance, use more safe and reliablely, realized lifelong sealing and non-maintaining purpose.3, the design that main bus bar links together in the bus-bar room, be the utility model design feature three.The purpose of doing like this is: can make the main bus bar that links together run through whole row switch cabinet, save indoor space.
Technical scheme: metal enclosed looped network switch apparatus, it comprises cabinet, cabinet top is bus-bar room, on-load switch chamber, operating mechanism and low-pressure chamber and separates by the cable vault of steel diaphragm and cabinet bottom, main bus bar links together in its bus-bar room, the on-load switch chamber is provided with on-load switch, and the cable vault is provided with lightning arrester, current transformer and cable.
The utility model is compared with background technology, and the one, compact conformation, flexible operation; The 2nd, safe and reliable, easy for installation, be convenient to simultaneously reequip highly versatile.
Description of drawings
Fig. 1 is metal enclosed looped network switch apparatus schematic internal view.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.Metal enclosed looped network switch apparatus, it comprises cabinet 8, cabinet 8 tops are bus-bar room 1, on-load switch chamber 3, operating mechanism and low-pressure chamber and separate with the cable vault of cabinet 8 bottoms by steel diaphragm 4, and main bus bar links together and runs through whole row switch cabinet in its bus-bar room., on-load switch chamber 3 is provided with on-load switch 2, cable vault's 6 base plate doors and in front of the door frame can be folded down, cable vault 6 is provided with lightning arrester 7, current transformer 5 and cable.The shell of on-load switch 2 be poured with epoxy resin form and in be filled with sulfur hexafluoride gas; Be provided with the spring operating mechanism and the mechanical interlocks of band position indicating device in the low-pressure chamber.In the low-pressure chamber is the relay control room, is convenient to carry out secondary control.
Embodiment 2: on the basis of embodiment 1, be provided with control loop, measuring instrument and protection relay in the low-pressure chamber.
What need understand is: though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection range of the present utility model.
