Description
Technical field
The utility model relates to a kind of combined electric appliance equipment technical field of the 40.5kV of being applicable to power transmission and transformation system, and specifically a kind of open type outdoor high-voltage is surveyed and protected combined electrical apparatus.
Background technology
In electric power system, transformer station is the assembly place of transmission and disttrbution.Transformer station is the flow direction of voltage of transformation in the electric power system, acceptance and distribution electric energy, control electric power and the electric power facility of adjusting voltage, and it gets up by the grid contact of transformer with each step voltage.Wherein the combined electrical apparatus of 40.5kV power transmission and transformation system is an electric equipment relatively more commonly used in the transformer station, its effect is under the electric power system normal operation, be used for closing and open circuit, and during fault faulty equipment with circuit disconnects or the electric equipment of automatic reclosing.Present domestic 40.5kV transformer substation construction all is to set up respectively with the open type element to form.This kind power plant construction type is taken up an area of greatly, the engineering overall cost is higher, and maintenance is inconvenient.Owing to the deficiency in the design, it is monitoring and protective device not in addition, and the fail safe and the stability of equipment are lower.
Summary of the invention
The purpose of this utility model provides a kind of compact conformation, and floor space is little, and the monitoring and protecting device is safe, and the open type outdoor high-voltage that stability is high is surveyed and protected combined electrical apparatus.
For achieving the above object, the technical solution adopted in the utility model is: a kind of open type outdoor high-voltage is surveyed and is protected combined electrical apparatus, comprise isolating switch, voltage transformer support and central console, also comprise fuse, lightning arrester, described support one end top is provided with the mechanism case that isolating switch, below are provided with isolating switch, the other end top of support is provided with voltage transformer, the below is provided with central console, on support, the inboard of voltage transformer is connected with fuse, the inboard of fuse is connected with lightning arrester.
Lightning arrester is fixedlyed connected with support by the compound porcelain sleeve of bottom with fuse, and lightning arrester on-line monitoring instrument is installed in the bottom of lightning arrester.
Support one end of the present utility model is provided with isolating switch, and the other end is provided with voltage transformer, and voltage transformer is connected with fuse, and fuse is connected with lightning arrester again, the arrangement compactness of this combined electrical apparatus, and floor space is little, is convenient to safeguard and maintenance; The utility model adopts fuse as overcurrent protective device in the electric power system, but when running into improper situation quick fuse, cut off circuit, reach the purpose of protection electrical network and electric equipment; Fuse and voltage transformer are used, and the monitoring device of forming device for the effect of secondary device metering and relaying protection, improves the fail safe and the stability of equipment; The utility model also is provided with lightning arrester, prevents or reduce that overvoltage or breaker operator overvoltage that direct lightning strike is derived cause damage to equipment.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
Now in conjunction with the accompanying drawings utility model is further described, the utility model mainly comprises isolating switch 1, voltage transformer 4, support 7, central console 5, fuse 3 and lightning arrester 2, described support 7 one ends top is provided with the mechanism case 8 that isolating switch 1, below are provided with isolating switch 1, the other end top of support 7 is provided with voltage transformer 4, the below is provided with central console 5, on support 7, the inboard of voltage transformer 4 is connected with fuse 3, the inboard of fuse 3 is connected with lightning arrester 2.Lightning arrester 2 in the present embodiment is fixedlyed connected with support 7 by the compound porcelain sleeve of bottom with fuse 3.Lightning arrester on-line monitoring instrument 6 also has been installed in the bottom of lightning arrester 2 in the present embodiment.
This arrangement compactness of the utility model, floor space is little, is convenient to safeguard and maintenance.The utility model adopts fuse 3 as overcurrent protective device in the electric power system, plays the effect of " fuse ".It is made up of the fusion tube of placing fuse member, contact electric-conductor and insulated support.In the power circuit of its main element fuse series connection; electric current by molten part when operate as normal should not make it fusing; when occurring overload or short circuit in the system, fuse will reach the purpose of protection electrical network and electric equipment because of overheated and fuse, cut off circuit voluntarily.Mutual induction of voltage thanks to device can be transferred to secondary device with the voltage signal situation of change in the electric power system, for secondary device metering and relaying protection purposes, fuse 3 is used with voltage transformer 4 in the utility model, the monitoring device of forming device can improve the fail safe and the stability of equipment; The lightning arrester 2 of the utility model setting can prevent or reduce overvoltage or the breaker operator overvoltage that direct lightning strike derives equipment is caused damage.Isolating switch 1 mechanism case 8 of the present utility model can be according to user and the different mechanism case 8 of engine request preparation, and what the mechanism case 8 of present embodiment adopted is the electronic interrupter of CJ-G.
This shows that the utlity model has compact conformation, floor space is little, monitoring and protecting Equipment safety height, stable high.
