Abstract
The utility model discloses a three-phase combined type overvoltage protector, comprising an installing plate, a grounding lightning arrester and a pillar insulator arranged on the installing plate, a conductive plate fixed at the upper ends of the grounding lightning arrester and the pillar insulator, and three main lightning arresters fixedly arranged on the conductive plate and electrically connected with external each-phase power supplies respectively. According to the utility model, by an ingenious structure cooperation, the three main lightning arresters and the grounding lightning arrester can be combined into a four-star type connection, so that the phase-ground and phase-to-phase overvoltages can be protected. The three-phase combined type overvoltage protector of the utility model enables the function that traditionally can be realized by needing six lightning arresters to be realized, at the same time, enables the defect that the simple star type connection method of three lightning arresters can not protect the phase-to-phase overvoltage very well to be overcome, and the three-phase combined type overvoltage protector is more reasonable and compact in structure, and safer and more reliable in work performance.
Description
Technical field
The invention belongs to the over-voltage protection technique field, be specifically related to a kind of three phase combined over-voltage protector.
Background technology
Three phase combined over-voltage protector is a kind of novel overvoltage protective device, is mainly used in 35kV and the following electric power system protection transformer; Switch; Bus, motor, electric equipments such as parallel capacitor; The switching overvoltage that atmospheric over-voltage and various vacuum circuit-breaker cause can be limited, relatively all reliable restriction can be played with alternate overvoltage.
The three phase combined over-voltage protector of generally selling on the market because structure is very unreasonable and the processing and manufacturing defective, causes field accident to take place frequently constantly, and its structure remains is needing improvements badly.
Summary of the invention
The purpose of the utility model provides comparatively rationally compact, the safe and reliable three phase combined over-voltage protector of a kind of structure.
The technical scheme that realizes the utility model purpose is: a kind of three phase combined over-voltage protector, comprise mounting panel, be arranged on earth arrester and post insulator on the mounting panel, be fixed on earth arrester and post insulator upper end conductive plate, be fixedly installed on the conductive plate three with external each main lightning arrester of power supply electrical connection mutually.
In the such scheme, said earth arrester and post insulator respectively are fixed on the mounting panel through a triangle metallic plate.
In the such scheme, said earth arrester and post insulator upper end height such as grade are provided with, and said conductive plate and mounting panel laterally arrange.
In the such scheme, also be provided with the counter fixed head on the said mounting panel, this counter fixed head is arranged in the middle of earth arrester and the post insulator.
In the such scheme, said three main lightning arresters are evenly distributed on the conductive plate.
The utility model is through structural ingenious cooperation, make that three main lightning arresters and earth arrester are capable of being combined to become four wye connections, thereby make each mutually, alternate overvoltage all is protected; The utility model can be realized traditionally needing six functions that lightning arrester could be realized, and having overcome simple three lightning arrester wye connections simultaneously can not the alternate superpotential shortcoming of better protection, and its structure is compactness comparatively rationally, and service behaviour is safer reliably.
