Product Description
CHZ9-12 Series Outdoor AC high voltage vacuum automatic recloser
1. Product Description
This product AC high voltage outdoor intelligent vacuum switchgear rated frequency 50Hz, rated voltage 12KV three-phase. It can replace the circuit breaker column alone; usually with high pressure slicer use together to form an intelligent power system protection features, flexible application of the urban network in the end 10KV substation, power ring road junction or on radial grid power lines, which not only has ZW32-12 vacuum circuit breaker with all the features and benefits, but also according to different protection requirements, flexibly arranged traditional three-current protection and over-current or speed off the anti-time protection.
Recloser reasonably selected according to the different power system protection requirements with the corresponding inverse - second curve, coincides interval reclosing operation parameters such as the number of gates, achieve multiple reclosing lockout and ultimately into the closing state functions to achieve automatic rapid elimination of transient fault, permanent fault isolation purposes segments.
2. Structure Introduction
Products from ZW32-12 / T630-20 type column vacuum circuit breakers, outdoor current transformer, CH automatic coincidence controller consists of three parts. Current transformer connected to the three-phase circuit breaker in the middle of outlet terminals, secondary wiring their secondary outlet inside the access mechanism and auxiliary circuit breaker together form, with a 20-core anti-electromagnetic interference by a control cable aviation plug coincide with the controller connected to controller provides automatic reclosing current change signal to the main road and its internal self-powered charging.
Automatic reclosing controller Based on a good parameter to control the circuit breaker, the sequence of operation set reclosing operation. After the main road when the current exceeds the speed setting value, the controller sends out automatic reclosing the opening command, the circuit breaker; after the first interval coincides breaker coincidence; on the line if the fault persists, the circuit breaker for the first the second opening and coincidence; if the fault is always present, the recloser reclose up to three consecutive four sub-gate closing operation after entering a locked state, the fault segments isolated.
