Abstract
The invention discloses a three-phase combined type over-voltage protector which comprises a structure, the structure is mutually composed of zinc oxide non-linear resistors and enlarged gaps, and each zinc oxide non-linear resistor and corresponding enlarged gap are arranged to protect each other. The three-phase combined type over-voltage protector is designed to aim at faults of conventional lightning arresters, and has a unique connection mode and a structural style over-voltage protector. The three-phase combined type over-voltage protector has the advantages of being novel in design idea, unique in structure, reasonable in parameters, small in volume, and convenient to install. Therefore, the three-phase combined type over-voltage protector has the domestic advanced level in the protection of high voltage motors and other electrical equipment.
Description
Technical field
The present invention relates to power supply unit technical field of auxiliary equipment, specifically belong to a kind of three phase combined over-voltage protector.
Background technology
Three phase combined over-voltage protector is a kind of novel overvoltage protection device, be mainly used in generate electricity, power supply and electricity consumption enterprise electric power network in.Be used for electric equipment such as protection transformer, switch, bus, motor etc., the switching overvoltage that atmospheric over-voltage and various switch cause can be limited, all can play reliable restriction to alternate and relatively overvoltage.
Summary of the invention
The object of this invention is to provide a kind of three phase combined over-voltage protector, the shortcoming that the present invention is directed to conventional lightning arrester designs, and has unique connecting mode and version overvoltage protection device basis.Invention design philosophy is novel, structure is unique, Rational Parameters, volume are little, easy for installation, has advanced international level at protection high-tension motor and other electric equipments.
The technical solution used in the present invention is as follows:
A kind of three phase combined over-voltage protector, comprises the structure having base, znr and amplification gap and mutually form, and makes both protect each other.
Described znr and amplification gap have four groups, adopt four star connections, all can play reliable restriction, alternate overvoltage can be reduced greatly alternate and relatively overvoltage between four groups.
Described znr adopts silicon rubber cover tire and the outer guiding structure of high-tension cable.
Described amplification gap adopts symmetrical structure, and the chargeability of ZnO resistors can be made to be zero.
Described base, built with explosion protection system, when overvoltage protection device because people and Yun Yin cause damage, all can avoid overvoltage protection device explode and cause short circuit accident.
Compared with the prior art, beneficial effect of the present invention is as follows:
The shortcoming that the present invention is directed to conventional lightning arrester designs, and has unique connecting mode and version overvoltage protection device basis.Invention design philosophy is novel, structure is unique, Rational Parameters, volume are little, easy for installation, has advanced international level at protection high-tension motor and other electric equipments.
