LW36-126 outdoor six sulfur fluoride circuit breaker

1, overview

LW36 - 126 type outdoor high voltage six sulfur fluoride circuit breaker is suitable for AC 110KV, 50Hz power system, is the power system control and protection equipment, also can be used as a contact circuit breaker.

LW36 - 126 circuit breaker in accordance with the requirements of GB1984-89 "AC high voltage circuit breaker" and EC56 the high-voltage alternating current circuit breakers, and circuit breaker with Se gas as insulation and arc extinguishing medium, adopts a self energy arc quenching principle, matched for ct30 type spring operation mechanism, has the strong breaking capacity and low operating power, high reliability characteristics.

LW36 - 126 use of environmental conditions:

The normal use of environmental conditions in line with the GB11022-99 "high voltage switchgear and control equipment standards of common technical requirements", that is, the:

A, ambient temperature of -30 to +40

B, not more than 3000 meters above sea level

C, the wind speed is less than or equal to 34m/s

D, on the temperature are less than 25

E, sunshine intensity less than 0.1w/ cm

F, monthly average relative temperature 90%

G, seismic acceleration level less than or equal to 0.2g, vertical 0.1g

H, the ice thickness is less than or equal to 10 mm

I, air pollution is not more than GB5582 in the third class

J, indoor installations

If the user has special requirements for the use of the environment, can be negotiated with the manufacturer.

In the narrative process of "attention" and "warning" two types of tips for "attention" of the relevant content,

If it is not possible to perform the inconvenience or slight injury, for the "warning" of the content, if not performed, it is possible to cause personal injury or equipment damage. These two types of tips are shown in bold type.

2, the structural characteristics of the product

LW36 126 circuit breaker adopts three-phase porcelain post structure for outdoor design. Three equipped with a spring operating mechanism, centered layout, three-phase linkage, so the appearance of novel exquisite. Circuit breaker with gas SE gas as insulation and arc extinguishing media, running circuit breaker three SE gas should be connected, and the use of pointer density relay on its pressure and density monitoring. Due to the adoption of the self energy arc extinguishing principle, the optimization design of the circuit breaker motion system is carried out, so the mechanical efficiency is effectively improved, and the operation work is reduced to a maximum extent.
