Intelligent lightning protection monitoring system lightning protection cabinet.
Jielitong lightning protection intelligent integrated cabinet installation method: please install it when the power supply is disconnected to avoid accidents.
1) Kevin wiring mode of intelligent lightning protection monitoring system (i.e., series wiring, there are incoming wires and outgoing wires, refer to Annex 1 for details): the power supply inlet (taken from the lower outlet side of the main switch in the front distribution cabinet, and the main cable between the outlet side of the original main switch and the distribution electric switch needs to be removed) "A, B, C, N" all pass through the residual current transformer, and then pass a, b, and c through a b respectively After the working current transformer of phase C is connected to the inlet terminal of the lightning protection box with the N line (2 terminals are set up in each phase, the incoming line is on the left and the outgoing line is on the right), and the A, B, C and N lines of the outgoing line are connected to the inlet side of the distribution electric switch in the front distribution cabinet. The power distribution PE wire entering the lightning protection box is connected to the "distribution grounding" terminal block in the box, and the lightning protection PE wire entering the lightning protection box is connected to the "lightning protection grounding" terminal block in the box.
2) Jielitong lightning protection intelligent lightning protection monitoring cabinet conventional parallel wiring mode: the power supply inlet (taken from the lower outlet side of the main switch in the front distribution cabinet, the main cable between the original main switch outlet side and the distribution switch does not need to be changed) directly connected to the inlet terminal of the lightning protection box, note that the high residual voltage of this wiring method is not conducive to equipment protection, and the working current and residual current can not collect data.
3) The intelligent integrated lightning protection cabinet does not need special maintenance, only need to regularly check whether its connection is loose and whether the working status indication is normal. It can also be maintained according to the alarm information of the host computer.
4) After the initial installation of the equipment, it should be powered on to detect, before powering on, it is necessary to use a multimeter to measure whether there is a short circuit in the phase line A B C to N line and PE grounding bar (power distribution and lightning protection grounding) in the box, and the device can be powered on only after confirming that there is no short circuit. After powering on, observe whether the display interface has a red indicator light, a stringing horn icon, a beep alarm, etc., if so, please follow 147. Troubleshoot and resolve exceptions.
5) Because this equipment can test 5 ways of grounding resistance, if the number of grounding points tested in actual use is less than 5 channels, then it is necessary to short-circuit the unused E terminal and the P terminal (for example, if the actual use of E1 E2 E3, E4 E4 is not used, then the E4 E5 terminal and the P terminal are short-circuited), if the unused E terminal is suspended, the circuit will be overrun alarm every time it is tested.
6) The surge protector in the JLT lightning protection cabinet is pluggable, and it must be checked for looseness before operation (during daily maintenance). Intelligent integrated lightning protection cabinet
