Product Description

Electric Handcart and Ground Knife Integrated Protector,It is a new type of integrated control device.It’s developed based on KYN 88 type and KYN 28 switchgear of high voltage power system.

It realizes the functions of electric on/off brake, one-key operation and one-key start for the longitudinal rotary isolation vacuum circuit breaker or handcart.It meet the technical requirements of the State Grid standard.And the longitudinal rotation isolation circuit breaker, handcart, ground knife in the whole electric operation process, the millisecond level of intelligent measurement and control and protection,Avoid the damage to the whole set of switchgear caused by motor clogging or idling failure.

This device can be applied to KYN 88 cabinet and KYN 28 cabinet.The series of products are widely used in electric power,chemical industry ,railway,mining,metallurgy,cement and many other industry. It’s very important to the smart power grid and power safety.

Product Function

• The working power supply adopts the wide voltage input design，AC/DC48 -240V；
• With a dual-motor independent power supply design，it can meet the needs of different applicant sites；
• With a motor working power supply,It can indicate independently When power on ；
• Provide linkage protection for the position state of the isolation knife (handcart) and the ground knife,Avoid accident caused by operational errors；
• The product has blocking and overflow protection.
• Product has idling timeout protection
• With remote and local operation function,it can realize smart grid remote control;
• With the programmable function, users can make different parameter configuration according to different applications.
