[Product Name]: GG-1A switchgear

【 Detailed content 】: GG-1A (F) type fixed metal enclosed AC high voltage switchgear 1、 Overview GG-1A (F) type switchgear is a protective AC high-voltage vacuum switchgear. Widely used in high-voltage electric vehicles The machine can be operated frequently in situations such as starting, switching, and running without the risk of explosion or fire. The GG-1A (F) series switchgear has complete anti misoperation program lock functions and is equipped with anti load opening and closing isolation switches; Prevent operators from accidentally entering live compartments; Prevent hanging grounding wires when live; Prevent closing the isolation switch with grounding wire; Prevent misclassification The circuit breaker has five anti misoperation functions and reliable performance. Vacuum circuit breakers have high vacuum insulation and strong arc extinguishing ability, which makes Long service life and easy maintenance. 2、 Structural description The switchgear frame is welded with angle steel, and the panels and partitions are made of thin steel plates. The primary and secondary components are separated from each other Separate from each system. There are doors, operation panels, and error prevention mechanisms on the front, and protective plates on the side to separate them. Front upper right corner of the switchgear It is the door of the circuit breaker room, and the cable room door is located at the bottom right. The middle partition divides the inside of the switchgear into two parts: upper and lower. The upper part has Circuit breaker room, relay room, instrument panel, and the lower part is the cable room. The isolation switch is installed on the top of the cabinet, with a partition in the middle Separate the board from the circuit breaker. Vacuum circuit breakers, isolating switch operating mechanisms, etc. are located in the circuit breaker room; The current transformer is in the middle On the partition; Zero sequence transformers and other equipment are installed inside the cable room. The circuit breaker operating mechanism is installed on the lower left side of the front of the cabinet. Second time Instruments and components are installed on the dashboard and relay room. The closing of the upper isolation switch and the opening and closing of the upper and lower doors are controlled by the program lock. When the isolation switch is closed, the upper and lower doors cannot be opened When the upper and lower doors are opened, the isolation switch cannot be closed.
