Hydraulic spring operating mechanismDetailed product description：

Overview
1. Product model and name
CYTB-4 hydraulic spring operating mechanism
2. Main purpose and performance of the product
2.1 This institution is used to operate 252KV high-voltage SF6 porcelain column circuit breakers and fully enclosed GIS composite electrical appliances. All performance indicators have reached the level of similar imported products and obtained utility model patents.
2.2 Single pole circuit breaker with single operating mechanism, achieving single pole operation, can be manually opened and closed slowly, locally manually opened and closed quickly, and can be quickly opened and closed locally through electronic control; Remote electric quick opening, closing, and reclosing. And it can achieve three pole operation.
2.3 The operating mechanism has the ability to issue interlocking signals for reclosing, closing, and opening when the system oil pressure drops to the limit value, and can achieve operational interlocking.
2.4 The operating mechanism has the performance of not experiencing slow tripping when the oil pressure drops to zero in the closed state and the oil pump motor is restarted to establish oil pressure.
The operating mechanism is equipped with a safety valve and has the function of self-protection in case of abnormal system oil pressure.
Environmental conditions for use
1. Environmental temperature -25 ℃~40 ℃
2. Relative temperature of 90%, monthly average not exceeding 90%; The daily average is not greater than 95%.
3. Maximum daily temperature difference of 25 ° C
4. Usage location: indoor or outdoor
5. Protection level IP54
