XGN -12 Intelligent solid insulation ring main unit

Overview

The XGN -12 Solid insulation Ring Main Unit Switchgear is an environmentally friendly composite insulation ring main unit developedindependently by our company. it is a fully sealed power supply unit, with allive components and switches fully enclosed within an epoxy resinhousing, which contains no SF6 gas. The entire switchgear is unaffected by external environmental conditions, ensuring operational reliabiity andpersonal safety,and achieving maintenance-free operation.

The solid-insulated ring main unit consists of three switch units: the V unit (circuit breaker unit), the C unit (load switch unit), and the F unit(combination appliance unit). Each unit can be used independently or expanded freely. its structure incudes an inteigent control instrument roomand is connected to dedicated terminals and busbars, The arc-extinguishing chamber emplovs specialized copper-chromium contact materialsan R-type longitudinal maqnetic field contact structure, and an improved incomplete primary sealing process, The operating mechanism uses anintegrated spring-operated mechanism that is fuly compatilble with the switch, meaning the isolating switch and main switch spring-operatedmechanisms form a single unit, This faclitates interlocking, reduces the number of mechanical components, minimizes unnecessary transmission linksenhances reliability, and allows for electric operation according to user requirements.

Product Description

The exposed surface of the insulating parts of the main components can be coated with a semiconductor shield according to user requirements toground it to eliminate electrostatic induction. As a result, the safety of use is greatly improved. The operating mechanism of the high votage circuitbreaker adopts a spring mechanism or a permanent maanet mechanism, and the mechanical ife is 10.000 times. All the operating data and equipment conditions can be remotely monitored and monitored, and can be unattended, which is actualy a superior performance power distribution device.

The inteligent device has the characteristics of simple structure, fiexible operation, relable interlocking, convenient instalation, etc. lt can providesatisfactory technical solutions for diferent applications and diferent uers, The appication of sensing technology, automatic control technology and information technology, coupled with advanced technical performance and simple and fiexible assembly schemes, can meet the changing needs of themarket and apply to the inteligent requirements of the power grid.

The ring cabinet is suitable for 50Hz, 12 kV power system, widely used in industrial and civl cable ring network and distribution network termina projects.

As the acceptance and distribution of electric energy, it is especialy suitable for distribution in urban residential areas, small secondary substations opening and closing stations, cable branch boxes, box-type substations,indutrial and mining enterprises, shopping mals, arports, subways, windpower generation,hospitals, stadiums, railways, tunnels and other places.

Because the product has the advantages of full insulation,fullsealing and full shielding, it is especially suitable for use in areas with harsh environment such as high altitude, high temperature, hot and humid, cold and serious pollution.
