  After JN15-12/D31.5 Motorized earthing switch is installed, according to the following steps for debugging:

  1. Read the specification of REC-10-HB switchgear electric control device.
  According to the wiring terminal diagram of REC-10-HB switchgear electric control device sample, connect electric earthing switch wiring terminal in accordance with the electrical diagram terminal number.

  2. Motor earthing switch terminal is pluggable terminal block. When complete connection,before testing power-on, user should pull out terminal, hang measured terminal 1.2 foot motor power During press the switch knob of electric control device,need insure 1 foot is positive power(VDD), ) foot is negative power(GnD ). If wiring is correct, then plug termina

  3. By test, observing whether the indicator light function of ERC-10-HB switchgear electric control device is correct. If not correct, please check the correctness of terminal and in place of signal source of switch opening, closing is correct or not.

  4. Manual operate earthing switch opening-closing, observing whether the display of electric control device is correct. If correct, can debug by motor operation.

  5. Special note of motor operation test: switchgear electric control device send intruction of earthing switch opening or closing. If the operating conditions are met, then will perform earthing switch opening or closing operation, observing whether the mechanism rotation direction is correct. If mechanism rotation direction is opposite, user should immediately turn off the power or press the scram button on device to stop the current operation, try again after changing moter positive and negative terminals. If the operating conditions are not met,(such as the interlocking signal of control device 11 foot is not correct), control device will not work properly, the user should settle accordingly to meet the operating conditions and try again.

  6. The switch off motion and the signal of the opening and closing reaching of the electric earthing switch are subject to the connect between operating shaft cam arrangement and microswitch. When electric earthing switch is connected with cabinet interlock, we should offer electric control device power supply, Combining with the control device opening and closing indicator light, manually adjust the opening and closing reaching of earthing switch(note:Wher the spring of earthing switch is just over dead point,the operating handle should seize up immediately), observe whether the control device opening and closing indicator light can synchronously indicate or not. Otherwise, we should adjust the upper and lower position of twin thread screw in the interlock to make them synchronously. If interlock position error is too big to reach synchronic we should make a fine adjustment in position between micro-switch and cam, and then observe control device just to make the corresponding indicator light.

LYE102 JN15-12 Indoor AC Isolation Switches High Voltage Earthing Switch With Sensor

• Specification
• Technical Parameters

• LYE102 JN15-12 Indoor AC Isolation Switches High Voltage Earthing Switch With Sensor
  

  JN15-12 indoor high-voltage earthing switch is suitable for indoor 3~12KV three-phase AC 50(60)Hz power system and various types of high-voltage switchgear, and can also be used for grounding when overhauling high-voltage electrical equipment. The earthing switch has a simple and compact structure, light weight, flexible operation, easy installation and good dynamic and thermal stability.

  Structure 
  Main structure: The earthing switch has a bracket, grounding knife assembly, static contact, sensor, shaft, inflection arm, pressure spring, conductive casing and soft connection.

  Note: The bracket is bent from a thin steel plate and welded into parts, the rest are assembled parts.

  Working principle
  a. When operating the operating mechanism to close the earth switch, as the torque makes the spindle overcome the resistance torque, drive the inflection arm to rotate along the closing direction, and make the manipulating rod on the earth knife pass through the dead point of the pressure spring, the pressure spring releases energy to make the earth switch close quickly, in the closing position. The grounding knife on the grounding knife assembly is firmly and reliably contacted by the disc spring and the flange part of the static contact.
  b. When the switch is opened, the moment of action causes the spindle to overcome the main moment and the spring force, driving the inflection arm to rotate in the direction of opening and causing the grounding knife pressure spring to pass through the dead point and the pressure spring energy storage to end for the next closing.
  c. The grounding switch and the closing speed are independent of the operating speed of the person.

  Feature

  1.JN15- 12 indoor AC high voltage earthing switch is Advanced design and steady performance.

  2. Simple structures, installation and adjustment.

  3. Fast breaking and making capability.

  4. Handsome appearance and delicate manufacture craft.

  5. Usable and scientific apparatus, be operated on both sides(right and left).

  Environmental conditions
