High applicability: CJTKA electric actuator can be equipped with 252kV, 363kV and 550kV outdoor disconnecting and grounding switches; CJTKB electric actuator can be equipped with 145kV, 126kV, 72.5kV and 40.5kV outdoor disconnecting and grounding switches.
CJTK motorized mechanism is highly reliable:
The transmission system operates smoothly with low impact, reliable self-locking and low noise;
The limit device of the mechanism can effectively prevent the output shaft from continuing to rotate that may occur after the parting and closing are in place, ensuring that the disconnecting switch (earthing switch) is not damaged;
The interlocking device of the mechanism can meet a variety of interlocking and five-proof blocking functions, which can effectively prevent misoperation;
The box body of the mechanism is made of stainless steel plate, with reasonable structure, beautiful appearance and reliable anti-corrosion performance;
box cover adopts convex table structure, which effectively improves the strength and prevents the accumulation of water; the sealing of the box body and output shaft adopts double-lip skeleton oil seal, and the box door and top cover adopts polyurethane foam sealant, which is elastic, aging-resistant, and has good waterproof and dustproof effect, and meets the requirements of protection grade IP55;
The overall structure of the mechanism is simple and reasonable in layout, and the parts are interchangeable; the front and side doors of the mechanism can be opened when needed, which is convenient for inspection and maintenance or replacement of parts;
The mechanism is connected to the disconnecting switch (grounding switch) by a clamping plate type, which does not require on-site welding.
