GG1AF high voltage switchgear, GG1A high voltage switchgear opening and closing operation

The basic skeleton of GG-1AF (Z) high-voltage switchgear is welded with angle steel. The front panel, the front door, the cabinet partition, the terminal side panel and the cabinet partition are evenly bent into thin steel plates. The front left door of the switch cabinet is equipped with monitoring instruments, relays, indicator lights and operating elements, and the secondary components such as relays and watt-hour meters can be installed in the small room of the door, and the watt-hour meter is indicated by the observation window on the door.

The middle left of the front of the cabinet is the operation board, and the operating mechanism is installed. A closing contactor and a fuse are installed in the small door in the lower left corner. The long door on the right side of the operation panel is installed with a terminal row for the secondary circuit and a cabinet light.

The upper and lower doors on the right side of the front of the cabinet are equipped with observation windows, which can observe the movement of the electrical equipment in the cabinet. The right upper door is equipped with a live display device to detect the live condition of the circuit. The cabinet is separated by a thin steel plate into the upper part is the circuit breaker room, the lower part is the isolation switch room, and the cabinet can be installed with a contact bus.

Components such as current transformers can be installed on the separator. The upper bus isolating switch is equipped with a partition plate between the circuit breaker, and the main bus is installed on the support insulator on the top of the cabinet. The bus bar can be selected as aluminum bus bar or copper bus bar as required.

The electrical clearance is not less than 125mm. The bypass scheme is to add a 600mm deep attached cabinet behind the main cabinet, the attached cabinet is protected by the back door and the operation panel, and the rear door and the front door of the main cabinet are equipped with a reversible mechanism interlocking: the front door is opened, and the back door can be opened - maintenance safety; The front door can only be closed when the back door is closed – safe to operate.

The primary circuit scheme of the switch cabinet is shown in Table 3. The general type shown in the table is GN24-12 for the combined disconnector with grounding knife. The simple type of isolating switch is GN19-12, the grounding element is the grounding pile, and the wiring diagram is similar to the general type, and is not shown separately.

Don't use obsolete products, use 8DJH high-pressure ring main unit.

Why do you still use such an old high-voltage cabinet and eliminate it.

Summary. GG1A high-voltage switchgear opening and closing operation Hello, pro, high-voltage switch closing and opening operation procedures 1. Closing operation 1. Open the back door of the cabinet, check the position of the grounding knife, and ensure that the grounding knife is in the disconnected state; 2. Open the door of the relay room in front of the cabinet, check the air circuit breaker in the relay room in the "closed" state, I hope mine is helpful to you, thank you, I wish you all the best and a happy life.

That's upstairs is kyn, not gg1a

It's not gg1a upstairs, don't mislead people.

1. The design is good, with a high degree of standardization, although each manufacturer has different names for GGD low-voltage switchgear, and the appearance will be different, but basically there is little difference, and the size of the parts used is the same, for example, the general internal selection of products is also a standard product on the market, but the use of materials may be a little different, and the material is different. Xiangtai Electric - low-voltage switchgear.

2. The GGD low-voltage switchgear is cheap, because the accessories and internal switches used are relatively standard products on the market, so that the standard mass production cost can be well controlled.

3. The use of GGD low-voltage switchgear is large, and it can be seen in general power distribution occasions, so there are more opportunities for operation and maintenance personnel to contact, and they are more familiar with how to operate and maintain for a long time, which can effectively reduce misoperation and can be better maintained to reduce the occurrence of accidents.

4. The design is reasonable and the technology is reliable, so through so many years of operation in the power grid, the stable performance of the product has been shown.

GGD AC low-voltage distribution cabinet: G--low-voltage distribution cabinet; g--Fixed installation, fixed wiring; d--Power cabinet.

GGD AC low-voltage distribution cabinet is used for power conversion, distribution and control of power, lighting and distribution equipment at AC 50Hz for power users, factories and mining enterprises.

GGD type AC low-voltage distribution cabinet is a low-voltage distribution cabinet designed according to the requirements of the competent superiors of the Ministry of Energy, the majority of power users and the design department, in line with the principles of safety, economy, rationality and reliability. The product has the characteristics of high breaking capacity, good dynamic and thermal stability, flexible electrical scheme, convenient combination, seriality and practicability, novel structure and high protection level. GGD type low-voltage switchgear conforms to EC60439 "Low-voltage switchgear and control equipment", low-voltage switchgear and control equipment Part I:

Type test and part of the type test complete set of equipment" and other standards.

1. GG-1A is the traditional old bai

Cabinet type, if it is an outgoing du

Cabinets, surface zhi board mostly use electromagnetic relay dao

Electrical appliances are generally protected by specialized.

Four current relays, a time relay, two signal relays, and an outlet intermediate relay form a two-phase two-relay current protection, as shown in the following figure

2. If it is a voltage transformer cabinet, there may be four voltage relays on it, which measure the three-phase voltage of A, B, and C respectively and the voltage of the open triangle.

High-voltage switchgear is generally smiling.

Five-proof locking refers to:

1. Prevent mis-dividing and closing of circuit breakers.

2. Prevent the disconnector from splitting and closing with load.

3. Prevent live hanging (closing) grounding wire (grounding switch).

4. Prevent the circuit breaker (disconnector) with grounding wire (grounding switch).

5 Prevent mistakenly entering the live interval.

GG1A is a fixed 10kV indoor differential high-voltage switchgear with anti-false shooting and misoperation locking device.
