Model and meaning

Technical parameters

1. GG-1A(F) fixed indoor AC metal-enclosed switchgear is an improved derivative of GG-1A high-voltage switchgear. It is an anti-accidental locking device and improvement on the original GG-1A high-voltage switchgear. Grounding system to meet the following five prevention requirements:
1.1 Prevent the opening and closing of the isolating switch under load
1.2 Prevent the mistaken entry into the live interval
1.3 Prevent the mistaken opening and closing of the circuit breaker
1.4 Prevent the live ground wire from being hung
up 1.5 Prevent the grounded wire from closing the isolating switch
2. Each line plan of the switchgear has two five-proof locking plans, namely the general locking plan and the simple locking plan, for users to choose. The general locking plan is to set a single phase Or a three-phase solution with a grounding switch. In this solution, the blocking cabinet is mainly mechanically locked. Supplemented by program locks and high-voltage live display devices to achieve five defenses. Generally suitable for overhead incoming and outgoing lines of substations (stations).
The simple locking solution is to set up a simple grounding stake to hang the grounding wire for power outage maintenance. This solution can be equipped with a blocking cabinet, a door panel can be installed behind the cabinet, or it can be installed on the wall. It basically uses mechanical locking to achieve the five preventions. If necessary, high-voltage electrification should be used. Display devices and program locks. In order to meet the needs of our customers, our company undertakes the production of new cabinets and can also assist in the oil-free transformation of old cabinets (that is, using vacuum circuit breakers to replace oil-less circuit breakers).
Ordering instructions
When ordering, the user must provide the main circuit and auxiliary circuit plans, the main electrical component model specifications, the main circuit plan combination arrangement diagram, and also indicate:
1. Single busbar cabinet
a. Whether to install against the wall or with a blocking cabinet,
b. Whether to use Whether the single-phase grounding switch uses a simple grounding pile terminal or not, there is no explanation. It is supplied according to the wall-mounted, simple grounding pile terminal, and simple locking solution.
2. Single busbar with bypass cabinet
a. Is it an indoor bypass (the outlet side isolating switch and the bypass isolating switch are installed in the blocking cabinet) or an outdoor bypass (the outlet side isolating switch and the bypass isolating switch are installed outdoors).
b. Whether to use a single-phase grounding switch or a simple grounding pile terminal.
c. Whether the bypass isolation switch adopts program locking or electromagnetic locking.
No above explanation was given. It is supplied according to the indoor simple locking scheme (simple grounded pile end electromagnetic lock).
