I. Overview
The DSN3 series indoor electromagnetic lock is an electronic control mechanism interlocking device that prevents the high-voltage switchgear electrical equipment from malfunctioning. It is mainly applicable to the front and rear cabinet doors, isolation switches, circuit breakers, grounding wires, etc. of indoor high-voltage switchgear, which need interlocking parts to realize interlocking to prevent the occurrence of misoperation. It is an indispensable locking device for power generation and power supply departments. In addition, in order to meet the needs of integrated automation substations, this series of electromagnetic locks also added auxiliary contacts within the lock. The user can be provided with a pair of corresponding switch contacts in the position of the lock, which is convenient for the user to interlock with each other and comprehensive automatic sampling, avoiding the empty space, and is an ideal locking device for the modern substation equipment. The patented product "Electric Control Lock" solves the defect that the mechanical program lock key cannot be controlled and managed in the integrated automation substation.
Second, the main technical parameters
1, working voltage AC and DC 220V, 110V
2. Auxiliary contact: current ≤ 3A
Current ≤ 6A (breaker blocking)
3, the use of environment a, temperature: upper limit +40 ° C
Lower limit -25 °C-----10 °C
b, humidity: daily average is not more than 95%, monthly average is not more than 90%
Third, use and scope of use
This product is an electronic control mechanism interlocking device that prevents electrical misoperation of high voltage switchgear. It mainly provides forced interlocking for high voltage switchgear cabinet doors and other places where safety interlocking is required to prevent accidental intrusion interval and misoperation. It is an indispensable locking device for the power generation and power supply departments.
Fourth, normal working conditions
Ambient air temperature: upper limit +40 ° C, lower limit: general area -10 ° C, alpine area -25 ° C.
Altitude: The altitude of the installation area is not higher than 1000m.
Ambient humidity: The average daily relative humidity of the air is not more than 95%, and the monthly average is not more than 90%.
Environmental conditions: no obvious pollution, no flammable, explosive, chemical corrosion and salt spray and no frequent and severe vibration.
Five, installation instructions
Electromagnetic door lock installation steps:
1. Remove the M5 nut, spring washer and flat washer of the panel mounting screw in turn;
2. Insert the lock bolt side of the lock body into the opening from the outside of the cabinet door, and then rotate the lock body to install the mounting screw on the panel into the 60mm hole of the cabinet door, and make the lock panel and the cabinet door panel smooth;
3. Install the flat washer, spring washer, M5 nut onto the M5 screw on the lock panel from the inside of the cabinet door, and finally tighten the M5 nut.
Electromagnetic door lock instructions
(1) Normal operation steps:
a, press the button, the power is turned on, the electromagnet coil is electrically operated, the moving iron core is separated from the lock bolt block, and the unlocking indicator light is on, indicating that the unlocking is allowed.
b. Rotate the handle in the direction of unlocking (clockwise in the left direction and counterclockwise in the right direction). When the force is applied to the limit position, the bolt will automatically return to the locked position, and the door can be opened. If the lock position is not reached, the lock bolt automatically returns to the lock position. When the automatic reset function is satisfied, the lock bolt is in the lock open position, and the handle is required to be turned to the lock lock, that is, the lock bolt returns to the lock position, thereby satisfying the lock. status.
Note: A, B lock shape, installation size is the same
(2) Operation method: A, dial the button B, pull the handle
(3) Manual unlocking steps:
a, the button is pressed, the power is forcibly cut off by the locking circuit, the unlocking light is not bright, and the moving iron core is stuck with the locking bolt block, which indicates that the unlocking is not allowed;
b. In special circumstances, when unlocking, remove the key and insert it into the unlocking hole. Press the panel to mark the turning key 90° to “-†or “stop†to push the moving iron core away from the locking bolt block;
c, (same as normal step b) to meet the "manual unlock" function.
Note: The unlocking process of the unlocking key is to push the moving iron core away from the locking bolt block to release the locking state. The unlocking must use the dial or the handle to move the locking bolt to unlock the lock, so the unlocking key cannot be used directly. unlock.
