Non standard customized 35KV solid insulation inflatable cabinet

1Overview

XGN □ -40.5 Cabinet Gas Insulated High Voltage SwitchgearIt has very high security and reliability, and can ensureThe continuous and stable operation of the power system and the personal safety of operators, as well as the humanized operation surface, are easy for on-site operators to operate，*Meets the latest environmental requirements.XGN □ -40.5 cabinet type gas insulated high voltage switchgear * is suitable for public and industrial distribution networks, infrastructure engineering, mining, metallurgy, petrochemicals, fuel and gas, railway power supply, container bases, and shipbuilding industries. Mainly used in power plants, small and medium-sized generators, substations, high-rise buildings, industrial and mining enterprises, subways, electrified railways and other distribution systems to implement control, protection and detection of power supply systems and loads. It is particularly suitable for environments such as frozen soil in underground plateaus and tidal humidity.

1. Adopting innovative switchgear design concepts, there are multiple options to choose from. It is a gas insulated switchgear with a rated voltage of 40.5kV, a rated current of 1250A, and a rated breaking current of up to 31.5kA.

2. Designed as a single busbar system. This compact and modular switchgearFlexibility, maintenance free throughout the lifespan. It is also very suitable for places with limited space or situations where old switches are upgraded and renovated using existing foundations.

3. It is an economical switch that can be assembled, expanded, or removed from the front of the switchgear. Due to the innovative busbar connection, no gas treatment operation is required on site.

2、 Design Features
•low pressureSF6 gas insulation

•modularizationdesign

The stainless steel shell is welded by a fully automated robot，There are single chamber and double chamber, which can adapt to different technical requirements;The circuit breaker and the three position switch are installed in separate chambers during the dual chamber operation

The busbar connection adopts a plug-in typeSolid insulated busbar connector，Not involved in the splicing of switchgearSF6 gas sealing work,No need for gas recovery and replenishment operations

Each independent chamber is equipped with a dedicated pressure release channel

•dedicatedInternal Cone Cable Insertion SystemSecure and reliable connectionadvantagesafety

Each functional compartment achieves * isolation

High voltage components are enclosed in a sealed chamber filled with SF6 gas, unaffected by external environmental factors

The insulation performance is not affected by the altitude of the site

IIIMinimize space requirements

Using SF6 gas insulation to minimize cabinet size

Compared to traditional switchgear, space savings can reach up to 70%

4economy

• More convenient operation, greatly reducing on-site construction period

• Not affected by external environment, thus obtaining a longer service life

Less maintenance requirements meanSaved operating costs

The savings in infrastructure land and space brought by miniaturized switchgear，Significantly reduce the total investment cost

5Metal sealing and gas sealing

• Adopt SF6 gas insulation

The busbar room is a sealed inflatable compartment

The circuit breaker room is a sealed inflatable compartment

• Rated voltage 40.5 kV

The maximum rated current can reach1250 A， Disconnected reachable31.5kA

VIcircuit breaker

•Horizontal placement of circuit breaker poles

The operating mechanism is located outside the chamber and in front of the cabinet

The pull rod between the circuit breaker pole and the mechanism is connected through a reciprocating sealing sleeve

• Cooperate with the three position switch to achieve grounding function，Three position isolation switch as busbar isolation switch and feeder grounding switch; When used as a line side grounding switch, it can be used in conjunction with a circuit breaker to achieve fast grounding function;Circuit breakers have better short-circuit closing ability than grounding switches，More frequent opening and closing operations can be performed for faults，Vacuum disconnection will not causeDegradation of SF6 gas insulation quality
