Product details

summary:

The ZLGTRM-12 series solid insulated enclosed ring network switchgear is a type of solid insulated vacuum switchgear that is fully insulated, fully sealed, and maintenance free. The high-voltage live parts are made of epoxy resin material with excellent insulation performance, which is cast and molded. The vacuum arc extinguishing chamber, main electrical circuit, insulation support, etc. are organically combined into a whole, and the functional units are connected through fully insulated solid busbar. Therefore, the entire switchgear is not affected by the external environment, ensuring the reliability of equipment operation and the safety of operators.

This ring main unit has the characteristics of simple structure, flexible operation, reliable interlocking, and easy installation. It is suitable for 50Hz, 12 kV power systems and widely used in industrial and civil cable ring networks and distribution network terminal projects. It is used for the reception and distribution of electrical energy, especially for urban residential distribution, small substations, switch stations, cable branch boxes, box type substations, industrial and mining enterprises, shopping malls, airports, subways, wind power generation, sports venues, railways, tunnels and other places.

Due to its advantages of full insulation, full sealing, and full shielding, this product is particularly suitable for use in harsh environments such as high altitude, high temperature, humid heat, severe cold, and severe pollution.

Product Category:

According to the type of switch, it is divided into load switch with grounding assembly (referred to as C module), load switch without grounding assembly (referred to as CB module), circuit breaker with grounding assembly (referred to as V module), circuit breaker without grounding assembly (referred to as VB module), circuit breaker interconnection switch (referred to as VZ module), load switch+fuse combination switch assembly (referred to as F module), and isolation switch assembly (referred to as G module).

Product functions and features:

environment protection

The materials used in product manufacturing are all non-toxic and harmless substances, and no toxic or harmful substances are emitted during use. The materials can be recycled and reused after their life cycle, which determines the environmental friendliness of their use.

Fully insulated, fully sealed, and fully shielded epoxy resin switch body and fuse body (epoxy resin has excellent electrical, mechanical, and thermal properties, and has been used in electrical equipment for a long time, achieving good performance. The switch body and fuse body are formed using epoxy resin APG process. Insulated casing is a key component of solid insulated switches, serving as both an insulating and load-bearing component. Require to meet technical requirements such as heat resistance, weather resistance, crack resistance, high mechanical strength, and good insulation strength simultaneously. Simplified Chinese has a large volume, numerous inserts, and various shapes, making it difficult to manufacture. Our company has many years of experience in designing and manufacturing insulation components. We have made efforts from simplified design, material formulation, and process flow to ensure the mass production of this component. According to user requirements, a cylinder with external shielding grounding that can be touched can be provided

Maintenance free:

The solid insulation indoor AC high-voltage vacuum switchgear is in a fully sealed state except for the operating mechanism, which can avoid cleaning and maintenance and reduce the cost of operation and maintenance.

Security:

Due to the use of shielding measures on touchable parts, the occurrence of personal electric shock accidents has been eliminated, improving safety and usability. A complete interlocking system, with clear and visible three-phase isolation fractures, avoids the occurrence of misoperation accidents. The application of SF6 gas has been cancelled, avoiding explosion accidents caused by insufficient gas pressure leading to a decrease in insulation performance and arc extinguishing ability of SF6 ring main units.

Strengthen the inter phase isolation structure to prevent the expansion or triggering of explosion accidents due to inter phase or multi circuit short circuits. Adopting a vacuum arc extinguishing chamber with explosion-proof performance, the switch sleeve provides further protection for the switch. The auxiliary grounding switch of the load switch fuse combination device is sealed in the fuse body with a vacuum switch tube.

Operability:

The isolation switch and grounding switch only have one operating handle, so there is no need to identify or worry about errors. When the circuit breaker is running, the operating handle of the isolation switch and grounding switch cannot be operated, and the operating procedure is clear at a glance. Anyone with a little knowledge of electricians can operate it, and complex technical training is carried out in a disorderly manner. This makes the operation exceptionally simple and prevents operational errors from occurring.

Intelligence:

The switchgear is equipped with intelligent interfaces and sensor installation positions, which can meet the requirements of the smart grid after configuring intelligent equipment.

Diverse operating mechanisms:

The switch can be equipped with two operating mechanisms: spring and permanent magnet, making it convenient for users to choose.
