Abstract
The utility model discloses a high pressure three -phase combination formula is from breaking away from zero clearance zinc oxide arrester device, including four high -pressure piezo -resistor pressure limiting device and three high -pressure hot melt disconnector, wherein three high -pressure piezo -resistor pressure limiting device divides three groups to establish ties with three high -pressure hot melt disconnector respectively, and three group links one -tenth star type, and the neutral point passes through a fourth high -pressure piezo -resistor pressure limiting device ground connection. The utility model discloses an alternate overvoltage can be solved to three -phase combination formula four stars type connection, adds the explosion -proof release of hot melt in the return circuit, can break away from the electric wire netting when the device breaks down, can not explode to guarantee the device reliability.
Description
Technical field
This utility model relates to power electronic product technical field, particularly relates to a kind of high pressure three phase combined from departing from zero-clearance zinc oxide lightning arrester device。
Background technology
In power system, vacuum circuit breaker uses ratio wide, in use, tens thousand of volt switching overvoltage often occurs, has threatened the safety of the person and equipment greatly。Present power system is to solve problems by installing spark gap additional。
Prior art arrester device has the disadvantage that:
1, pressure limiting effect is bad, it is impossible to limit alternate overvoltage。
2, easily heating is aging, even explodes, and reliability is not strong。
Utility model content
This utility model purpose is contemplated to make up the defect of prior art, it is provided that。
This utility model is achieved through the following technical solutions:
A kind of high pressure is three phase combined from departing from zero-clearance zinc oxide lightning arrester device, include four high voltage varistor pressure limiting devices and three molten disconnectors of hot high pressure, wherein three high voltage varistor pressure limiting devices divide three groups to connect with the molten disconnector of three hot high pressure respectively, and three groups connect into star-like, neutral point passes through the 4th high voltage varistor pressure limiting device ground connection。
The utility model has the advantages that: this utility model adopts three phase combined four wye connections can solve alternate overvoltage, loop adds the explosion-proof electrical apparatus release of hot melt, it is possible to departing from electrical network when device breaks down, will not exploding, thus ensureing device reliability。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model。
Detailed description of the invention
As shown in Figure 1, a kind of high pressure is three phase combined from departing from zero-clearance zinc oxide lightning arrester device, include four high voltage varistor pressure limiting devices 1 and three molten disconnectors 2 of hot high pressure, wherein three high voltage varistor pressure limiting devices 1 are connected with the molten disconnector 2 points three groups of three hot high pressure respectively, and three groups connect into star-like, neutral point passes through the 4th high voltage varistor pressure limiting device 1 ground connection。So can effectively limiting alternate overvoltage, hot melt electrical apparatus release can depart from electrical network when device breaks down, it is prevented that blast。The utility model has the advantages that: instant pressure limiting also can depart from electrical network when device breaks down, and will not explode, thus ensureing device reliability。
