LW36-126/1250-40 Outdoor Circuit breakers 110KVSF6

1 Overview

LW36-126 type outdoor high voltage SF6 circuit breakers for AC 50Hz, 110KV power system, power system control and protection equipment for power system can also be used as tie breaker to use.

LW36-126 breaker in line with GB1984-89 "AC high voltage circuit breakers" and EC56 "high-voltage AC circuit breaker" requirements, the circuit breaker to the SE gas is insulated and arc-quenching medium, self Extinguishing principle, equipped with CT30 type spring operating mechanism, with breaking ability, low operating power, high reliability.

LW36-126 use of environmental conditions:

Normal environmental conditions meet GB11022-99 "high-voltage switchgear and control equipment standards common technical requirements" which provides that:

A, ambient temperature -30 ℃ ~ + 40 ℃

B, no more than 3000 meters above sea level

C, wind speed ≤34m / s

D, daily temperature ≤25 ℃

E, sunshine intensity ≤0.1w / cm

F, monthly average relative humidity of 90%

G, seismic acceleration levels ≤0.2g, vertical ≤0.1g

H, ice thickness ≤10㎜

I, no more than the level of air contamination in GB5582 grade Ⅲ

J, indoor installations

If you have special requirements for the use of environmental conditions, it can be negotiated with the manufacturer.

In narrative carve "note" and "warning" categories prompted for the "attention" of the contents,

If execution may cause inconvenience or minor injury, for the "warning" of the content, if implemented, it is likely to result in injury or equipment damage. The two types of prompts are shown in boldface.

2, the structural characteristics of the product

LW36-126 three-phase circuit breaker porcelain pillar structure, designed for outdoor. A three-phase using a spring operating mechanism, placed in the middle, three connected move, so the appearance of fine new suspect. SE breaker with gas insulation and arc extinguishing medium for the gas, the gas SE Runtime three breaker should communicate and use pointer density relay to monitor its pressure and density. As a result of self-energy interrupter principle, and the circuit breaker motion system has been optimized, it is effective in improving the mechanical efficiency, minimize the operating power.
