1. Product Introduction

The HXGN - 12 (F, R) box - type fixed AC metal - enclosed ring - network switchgear is a new - type switchgear carefully designed to meet the needs of urban power grid transformation and construction. In the power supply system, it has the functions of breaking load current and short - circuit current, as well as closing short - circuit current. It is suitable for the distribution system of AC 3 - 10kV and 50Hz. The application scope of this equipment is very wide, covering fields such as urban power grid construction and transformation projects, industrial and mining enterprises, high - rise buildings, and public facilities. It can be used as a ring - network power supply unit or a terminal device, playing an important role in power distribution, control, and the protection of electrical equipment. It can also be installed in pre - installed substations.

2. Product Description

(1) Configuration of Core Components

This ring - network cabinet is equipped with a vacuum load switch and a spring operating mechanism. This spring operating mechanism has multiple operation modes. It can be controlled by manual operation or electric operation, providing convenience for users in different scenarios. In addition, the earthing switch and the disconnector are equipped with a manual operating mechanism, further ensuring the flexibility and reliability of equipment operation.

(2) Product Features

1. High integration: This ring - network cabinet has strong completeness, integrating multiple functional components into one, reducing the floor area and installation space of the equipment, and improving the overall compactness and layout rationality of the system.

2. Safe and reliable: The product is small in size and has no risk of combustion and explosion, greatly improving the safety during use.

At the same time, this ring - network cabinet has a reliable "five - prevention" function, namely preventing the accidental opening and closing of the circuit breaker; preventing the opening and closing of the disconnector under load;

Preventing the hanging (closing) of the earthing wire (earthing switch) when the equipment is live; preventing the closing of the circuit breaker (disconnector) with the earthing wire (earthing switch) connected; preventing accidental entry into the live compartment. These "five - prevention" functions ensure the safety of operators and equipment from multiple aspects, avoiding safety accidents caused by misoperation.

(3) Standard Compliance This ring - network cabinet strictly complies with relevant national standards and international standards.

Specifically, it complies with the standards of GB3906 "3 - 35kV AC Metal - Enclosed Switchgear" and IEC60420 "High - Voltage AC Load Switch - Fuse Combined Electrical Appliance", indicating that the product has reached a high level in terms of design, manufacturing, and performance, and can provide users with stable and reliable power control and protection solutions.
