Product Description

Product overview

SOGEAR solid insulated ring switchgear, adhering to Zhejiang Bowei Electric Co., LTD. On the solid insulation basic technology of in-depth research and secondary distribution power users in the new era of deep understanding of the development of the new – generation ring network switchgear. The application of green epoxy resin material instead of SF6 gas reduces the greenhouse effect and the environmental pollution and personal injury caused by its decomposing materials in the process of use. Fully insulated and fully enclosed, vacuum arc extinction, illustrated by the point/permanent magnet agency optional, visible isolation, reliable locking, compact branching technology features make SOGEAR solid insulated ring network switch equipment is very suitable for 12/24KV voltage level, 630/1250A rated current, 20/25KA breaking current and below the medium voltage distribution system, Such as ring network power supply, power distribution room, open and close, double radiation power supply secondary distribution applications.

Working principle of ring network cabinet

The working principle of China Sogear Solid Insulated Ring Network Switchgear is that the main power supply line forms a closed ring, the power supply supplies power to the main line of the ring, and then distributes power from the main line all the way through the high-voltage switch. The advantage of this is that each power distribution branch can draw power from its left trunk and its right trunk.

When the left main wire fails, it continues to get power from the right main wire. When the right main wire fails, it continues to get power from the left main wire.

In this way, although the main power supply is a single-way power supply, similar to the bidirectional power supply, it benefits from each power distribution branch and improves the reliability of the power supply of China Sogear Solid Insulated Ring Network Switchgear.

China sogear solid insulated ring network switchgear features

The Sogear Solid Insulated Ring Network Switchgear is a completely sealed system with a stainless steel tank containing all live components and switch functions. This constant and stable atmospheric condition and sf6 gas inside the tank ensures high reliability and safety for the operator, Sogear Solid Insulated Ring Network Switchgear supplier designed this way to make this equipment maintenance-free for 30 years.

The ring network cabinet is a set of high-voltage switchgear installed in a steel plate metal cabinet or assembled into a ring network power supply device. The core parts of the equipment are load switches and fuses.

China Sogear Solid Insulated Ring Network Switchgear has simple structure, small size and low price. Improve power supply parameters and performance, and improve power supply security. Widely used in power distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises.

Advantages of China sogear solid insulated ring network switchgear

1. Outdoor, fully insulated and fully sealed structure, China sogear solid insulated ring network switchgear can adapt to any harsh environment.

2. Visible fracture, confirm the switch contact position, to ensure personnel safety.

3. Small size, light weight, compact structure, small footprint.

4. China Sogear Solid Insulated Ring Network Switchgear is easy to install, easy to operate, safe and reliable, and maintenance-free.

5. The three-work linkage structure can effectively prevent the defective operation of the equipment.

To sum up, China Sogear Solid Insulated Ring Network Switchgear has the characteristics of safety and reliability, light weight, compact structure, simple installation, convenient operation, and suitable for various harsh environments.

Technical characteristics

Environmental protection and green new generation insulation technology

Epoxy resin, manufactured without pollution to the environment

After the end of the product life cycle can be used as ordinary waste, no pollution to the environment.

Do not use SF6 gas: Sogear Solid Insulated Ring Network Switchgear is the Kyoto Protocol should be reduced or prohibited use of greenhouse gases;

Sogear Solid Insulated Ring Network Switchgear  manufacturing, recycling, use process is not easy to manage; The biochemical characteristics of SF6 gas arc decomposition and reaction products after switching arc extinction have certain toxicity.

A complete test of sogear solid insulated ring switchgear

Type test: Insulation test, temperature rise, short-time and peak tolerance current, short-circuit current breaking ability and short-circuit closing ability, cable charging current, protection class, electrical life, mechanical life, internal arc burning test, and environmental test of solid insulation components.

Factory test: mechanical characteristics test, main circuit MIN power frequency voltage test, auxiliary circuit power frequency voltage test, main circuit resistance test, mechanical interlocking test, insulation component partial discharge measurement, operation test

Sampling test: insulation components local release test, insulation components high and low temperature alternating test

 

Reliable operation performance

The primary components are insulated by solid epoxy resin with shielding layer, and the surface can be touched at zero potential.

Single box design, and each phase separate insulation, avoid short circuit between phases. Fracture power frequency (1MIN) withstand voltage 58000V, phase and ground power frequency withstand voltage (1MIN)52000V, higher than the standard test standard. High reliability vacuum arc extinguishing technology, knife gate type isolating switch, optimized electric field structure design, can meet the 630A rated current /25KA breaking current, 1250A rated current /25KA breaking current two current configuration requirements.

The observation window on the panel can visually inspect the disconnecting switch fracture position; Perfect mechanical interlock, effectively avoid misoperation; The optimization design of anti-internal arc burning and the design of pressure relief channel guarantee the safety of maintenance personnel from all aspects.

 

Flexible configuration combinations

Single box modular design, compact and extensible, complete functional units, can be arbitrarily combined according to customer power distribution needs.

Three station/two station (split, close, grounding) mechanism optional configuration, to meet different requirements of customer standards.

User friendly interface, operation and interlocking instructions clear; The cable room has large installation space.

Spring mechanism/PERMANENT magnet mechanism is optional to meet the needs of conventional use and long mechanical life, fast separation and closing.

Microcomputer protection and power grid automation control equipment, cable fault indication, instrumentation and other intelligent electronic secondary equipment using standard communication protocols, easy to integrate or create a medium voltage distribution system.
