Product Overview
The DCR disconnector is an outdoor pole single-phase disconnector, which provides a visible break for maintenance personnel and can also be used as a breaking point. Its structure is a double-column disconnector, the insulator and bolt are locked on a hot-dip galvanized base, and the disconnector can be operated by pulling the ring. The limit level after the isolation knife is opened is 160 degrees by default (it can be changed to 90 degrees on the spot or removed to no limit on the spot). When installing the DCR disconnector, an optional mounting backplate can be clamped onto the cross arm to fix the switch.
Product description and Structure
The DCR disconnector is an outdoor pole single-phase disconnector, which provides a visible break for maintenance personnel and can also be used as a breaking point. Its structure is a double-column disconnector, the insulator and bolt are locked on a hot-dip galvanized base, and the disconnector can be operated by pulling the ring. The limit level after the isolation knife is opened is 160 degrees by default (it can be changed to 90 degrees on the spot or removed to no limit on the spot). When installing the GCD disconnector, an optional mounting backplate can be clamped onto the cross arm to fix the switch.
Technical Parameters
DCR disconnector is used in 12kV distribution network system, with a rated current of 630A, a short-time withstand current of 20KA/4S, a peak withstand current of 50KA, and the power frequency and lightning impulse withstand voltage can reach the level of 2000 meters above sea level.
Safety Matters
The person responsible for installing, maintaining and operating the disconnector should have instructions for use;
Follow your company's safety protocols;
Please read the instruction manual carefully before preparing to install, maintain and operate the disconnecting switch, so as to avoid incorrect operation of the switch and unnecessary casualties;
Switches must be operated and maintained by professionals familiar with safety procedures. The instruction manual is used as a reference material for operation and maintenance personnel, and cannot be used as a substitute for training and practice of safety regulations for such equipment.
Operate
DCR disconnector is a high-voltage device that is usually operated with standard electrically insulated tools, and care is taken to operate it correctly and safely;
The operator should use the insulated tie rod to pull the pull ring on the DCR is not completed, and the opening and closing operation of the DCR disconnector should be carried out under no load condition;
Double-column disconnector, insulator and bolt lock on a hot-dip galvanized low seat, pull the ring to operate the disconnector;
The limit after the isolation knife is opened is set at 160 degrees by default (it can be changed to 90 degrees on the spot or removed to no limit);
When installing the DCR disconnector, an optional mounting backplate can be clamped onto the cross arm to fix the switch.
