Abstract
The utility model relates to a combined type and grid-combined high voltage switchgear, comprising a one-time electric cable, an overvoltage protector, insulators, a current transformer, a lightning arrester, a relay room, a circuit breaker, a fuse, a voltage transformer and a tank bracket, which is characterized in that all the components are arranged inside the tank bracket, one branch of the one-time electric cable is connected with the circuit breaker by the lightning arrester and the current transformer; the other branch is connected with the voltage protector and the circuit breaker respectively by the insulators, the circuit breaker is connected with the relay room and the voltage transformer is connected with the overvoltage protector by the fuse. The combined type and grid-combined high voltage switchgear of the utility model has the advantages of small occupied area, saving the investment cost and complete functions.
Description
Technical field
The utility model relates to a kind of composite type grid type high-tension switch cabinet, mainly is used in the wind power generation preassembled transformer station that boosts, and belongs to the high-tension switch cabinet technical field.
Background technology
According to traditional design, realize the be incorporated into the power networks specification requirement of cabinet of " wind power generation boost preassembled transformer station " high pressure, need two high-voltage boards (incoming line cabinet that boosts+outlet cabinet) could realize system requirements at least.Yet " wind power generation boost preassembled transformer station " mostly is used in coastal beach or neritic province domain, and the cost of manufacture on basis can be very high.
Summary of the invention
The purpose of this utility model provides a kind of composite type grid type high-tension switch cabinet that reduces the cost of investment of transformer station.
For realizing above purpose; the technical solution of the utility model provides a kind of composite type grid type high-tension switch cabinet; comprise cable one time; overvoltage protection device; insulator; current transformer; lightning arrester; relay bungalow; circuit breaker; fuse; voltage transformer and tank bracket; it is characterized in that; all parts are located in the tank bracket; a cable lead up to lightning arrester; current transformer is connected with circuit breaker; another road is connected with circuit breaker with voltage protector respectively by insulator; circuit breaker is connected with relay bungalow, and voltage transformer is connected with overvoltage protection device by fuse.
The utility model carries out miniaturization Design to whole system, boost incoming line cabinet and two high-voltage boards of outlet cabinet in the former scheme are designed to a composite type grid type high-tension switch cabinet, the floor space of transformer station is also correspondingly dwindled, the installation foundation cost of transformer station also correspondingly descends, reduced overall cost of ownership, the composite type grid type high-tension switch cabinet after the design has still satisfied the requirement of related standards such as GB3906.
The utility model has the advantages that:
1. floor space is little, has saved cost of investment;
2. function is complete, and the insulating monitoring of the gentle overload protection of the mistake of set pair transformer, high-pressure system, current measurement, overvoltage protection are in one.
