Summary
Siemens 3AH5 vacuum circuit breaker is a new three-phase vacuum circuit breaker developed every year within 1997~1999 years, the nominal voltage is
7.2~12kV, can be used in power distribution system and the masses of industrial users extensively.
The vaccum arc chute of the circuit breaker adopts once to seal and arrange technology to make, the contact material is Cr-Cu alloy, smelted by the electric arc. Touch
Head adopt advanced the intersection of design and shape and structure, have very much high to able to bear electric arc ability and very much little arc pressure drop. So, are guaranteeing on-off amount
Under the prerequisite of the short circuit current, the volume of the arc chute can have minor size. Such new vaccum arc chute of Siemens, also have
Characteristic with small shut off value. So, the circuit breaker, in the on-off voltage transformer when one kind is supported perceptually, the operating voltage that will not be endangered,
Vaccum arc chute cooperate with fine mechanical property of operating of spring, make the intersection of Model 3AH5 and vacuum circuit breaker can succeed in, shut many times, divide the electric capacity
The device group, but will not have fired the voltage again.
The operating mechanism of the circuit breaker adopts the stored energy form of the spring, the stored energy that can be manual, also all right electronic stored energy. Each zero’s in this organization
The part underwent precision finishing, assembled it. Moreover, key part and material are made with the special craft. In this way, have guaranteed wholly
An operating mechanism has very small frictional force, cooperate with accurately between every part, movements are reliable.
For run mode and environmental characteristic of the suitable Chinese electric system, the circuit breaker has strengthened insulating strength, have increased the climbing of the insulator
From,increase by skirt porcelain at and it is at outer walls of arc chute vaccum.
The circuit breaker can be affixed to various typological switch cabinets by means of different installation, no matter fixed type or very withdrawing, its capital
Can suit, as to vaccum arc chute, the erection site of the vacuum circuit breaker is vertical.
Under the normal service conditions, this circuit breaker is totally non-maintaining in the 10000 times of operations.

Applicable technical data
3AH5 vacuum circuit breaker accords with IEC56, IEC694, all clauses of BS5311 and DIN VDE0670, and satisfy
China standard GB1984 and DL403 (insulating part) .
Influence of the environmental parameter
Design the normal operation in the following temperatures and the humidity according to the normal service conditions with 3AH5 vacuum circuit breaker:
Maximum temperature +40 degrees of C
24-hour average temperature +35 degrees of C
Minimum temperature -5 degrees of C
Allow the atmospheric humidity:
Relative medial humidity of 24 hours <95%
Relative medial humidity in one month <90%
The height above sea level: 1000m and the following area.
While exceeding 1000m as installing the place, need to calculate with the formula, obtains the insulation level at this moment.
2.5 Life time
Under the normal service conditions, the specified mechanical life of 3AH5404 circuit breaker is 20,000 times, 3AH5115 is 10,000 times,
