Overview

The CT23 type can be used to operate ZW □ -12 series outdoor high-voltage vacuum circuit breakers and other high-voltage vacuum circuit breakers with equivalent closing power. The operating mechanism has functions such as electric or manual closing, opening, and overcurrent protection, and its mechanical life is 10000 times. The CT23-D series is an improved electric mechanism newly designed by our company, which uses a magnetic DC motor and sprocket transmission for energy storage. It operates smoothly, has high reliability, good mechanical performance, and a long service life; The manual energy storage handle is installed inside the mechanism body, avoiding the leakage of water in the original component. Moreover, due to the pull ring being set at the bottom of the mechanism, the appearance of the mechanism is more beautiful, suitable for new and old outdoor 10KV column vacuum circuit breakers.

Main technical parameters of CT23-D spring operated mechanism (outdoor)

1. The output angle of the institution is 40 ° -45 °
2. The technical parameters of the opening and closing release, overcurrent release, and energy storage motor are shown in the table below
3. After the installation of CT23A-D mechanism and ZM1-10 outdoor high-voltage vacuum circuit breaker, the gap between the roller of the transmission shaft sleeve and the cam should be maintained at about 2MM before the closing spring has stored energy and is ready to close.
4. External dimensions of the mechanism: (1) 460 × 300 × 480mm
