Description
Technical field
The utility model is related to overvoltage protection device field, is protected more particularly, to a kind of Three phase combination overvoltage
Device.
Background technology
Overvoltage protection device is a kind of high-performance overvoltage absorbing device, mainly for the protection of generator, transformer, is opened
Infringement of the insulation of the electrical equipments such as pass, bus, motor, parallel capacitor group from overvoltage.Existing overvoltage
Protector typically uses three-phase three-limb or three-phase and four-pole formula.Due to sharing a neutral point, three, easy in four-column type structure
There is chain effect, the hidden danger of thermal runaway easily occurs for ground facies unit.Only to carrying out overvoltage protection between phase ground, and it is alternate
There is no overvoltage protection, cause certain potential faults.
Utility model content
The purpose of this utility model is to provide a kind of Three phase combination overvoltage protector not only to entering between phase ground
Row protection, while to carrying out overvoltage protection between phase phase, overvoltage protection is reliable, and the reliable cost of compact conformation is low.
To achieve the above object, the utility model provides a kind of Three phase combination overvoltage protector, including shell
Body and the protector main body for being arranged at the enclosure interior, the protector main body are provided with three phase connections and ground wire, and three connect
Line, which is provided between disconnector, each phase, is provided with metal oxide arrester, and three metal oxides between each phase are taken shelter from the thunder
Device, which is connected between delta connection, each phase and ground, is provided with metal oxide arrester, the metal oxidation of three between phase ground
Thing arrester is connected into star connection, and the metal oxide arrester is gapless metal-oxide lighting arrester.
It is preferred that, insulating materials is cast with the housing, the insulating materials is epoxy resin.
It is preferred that, the protector main body can also be in series with counter or monitor.
It is preferred that, the housing bottom is additionally provided with base, and the base both sides are provided with fixing hole, the fixing hole and are provided with
Ground loop, the ground loop is connected with the ground wire.
It is preferred that, the disconnector is vacuum contactor.
Therefore, the utility model uses a kind of Three phase combination overvoltage protector of said structure not only to mutually
Between protected, while to carrying out overvoltage protection between phase phase, overvoltage protection is reliable, and the reliable cost of compact conformation is low.
Below by drawings and examples, the technical solution of the utility model is described in further detail.

Three phase combination overvoltage protector shell structure schematic diagram is planted, as illustrated, including housing and being arranged at enclosure interior
Protector main body, protector main body is provided with three phase connections and ground wire, and disconnector is vacuum contactor 2, and long lifespan can use
, can be with the electric current between tripping protection device and equipment in the high device of operating frequency, and then protection equipment.Set between each phase
There is metal oxide arrester, to carrying out three metal oxide arresters between overvoltage protection, each phase between phase and phase
It is connected between delta connection, each phase and ground and is provided with metal oxide arrester, three metal oxides between phase ground is taken shelter from the thunder
Device is connected into star connection, to carrying out overvoltage protection between phase and ground, forms " star-triangle " structure as shown in Figure 1, realization pair
The phase of equipment overvoltage and phase phase overvoltage protection.Metal oxide arrester is gapless metal-oxide lighting arrester 1,
Gapless metal-oxide lighting arrester 1 is handled by densification all insulation, and insulating materials is cast with housing, and insulating materials is ring
Oxygen tree fat, solves sealing and the Insulation Problems of product, and compact structure is compact, and the part maintained in housing will not be random
It is mobile.Protector main body can also be in series with counter or monitor.Convenient management and monitoring.Housing bottom is additionally provided with base 3,
The both sides of base 3, which are provided with fixing hole 4, fixing hole 4, is provided with ground loop, and ground loop is connected with ground wire, it is not necessary to separately set ground connection spiral shell
Silk makes its compact conformation reduce the use of screw while reducing processing cost.
Therefore, the utility model uses a kind of Three phase combination overvoltage protector of said structure not only to mutually
Between protected, while to carrying out overvoltage protection between phase phase, overvoltage protection is reliable, and the reliable cost of compact conformation is low.
Above is embodiment of the present utility model, but protection domain of the present utility model should not be limited to this.Appoint
What those skilled in the art is in the technical scope disclosed by the utility model, the change or replacement that can be readily occurred in,
It should all cover within protection domain of the present utility model, therefore protection domain of the present utility model should be limited with claims
Fixed protection domain is defined.
