Product Description

live tank sf6 gas 330kv circuit breaker for substation

1.Brief Introduction

H.V. A.C.porcelain type SF6 gas circuit breakers, with voltage from 40.5-550kV and rated current up to 4000A, manufactured by our company, are provided with three kinds of operating mechanism, pneumatic, spring and hydraulic type.

Motor is used in spring mechanism to charge closing spring and charge opening spring at closing. Disk spring is used
in hydraulic mechanism to be charged in stead of traditional compressed nitrogen gas for charge, and hydraulic driving
is used at both opening and closing. Compressed air is used in pneumatic mechanism as driven force for open
while spring is used for close. The three kinds of operating mechanisms have their own features and are used in circuit
breakers of different voltage class respectively.Due to the unit structure in circuit breaker, there are advantages of minimized number of breaks,lower number of parts, simple structure,high reliability and long period of inspection.

4.Main Features and Advantages:


4.1 Superior interrupting capability

Unit structure is applied in this series products body with variable clearance. It can meet all switching requirements.
Either severe rate of rise of the recovery voltage by a short-line fault or high recovery voltage
peak by out-of -phase interruption are withstood by the efficiently designed interrupter.
In switching of magnetizing current, the overvoltage is less than twice operating voltage. No restrike or reignition
occur during switching of charging current.

4.2 Reliable insulation and current-carrying capability
Because of the isolation of SF6 gas from the atmosphere,the breaker has a reliable insulating capability.
SF6 gas does not deteriorate with age and at the same time it protects the insulators within the gas.It also
protects the contacts from oxidization and other chemical reaction as SF6 gas is stable and inert when it is
used together with most of other materials.

4.3 High reliability
The series products passed all type tests at National High Voltage Apparatus Quality Monitor and Inspection
Center. Mechanical endurance:3000 times without regulation and 10000 times with lubrication and
regulation permitted have been passed. It also passed electrical endurance test, breaking 20 times at rated
short-circuit breaking current (40kA/50kA/63kA) during type test.

4.4 Operating Mechanism
Spring operating mechanism and pneumatic operating mechanism, provided with circuit breaker, are professionally
manufactured by Sino-Japanese joint venture XD-Mitsubishi Co. with excellent performances.
Hydraulic operating mechanism, provided with circuit breaker.

4.5 Minimized maintenance work
The breaker is constructed by units, resulting reduced number of breaks and parts, and minimized inspection
and maintenance work. Due to operating mechanism with advaned technology, excellent performance,
it hardly need repair.

4.6 Excellent earthquake withstand capability
The porcelain type SF6 gas circuit breaker is substantially resistant to seismic shock and the safety is increased
due to simple construction and light weight.
