(1) The drawing of the wiring diagram and the wiring table shall be subject to the request of GB6988.6-1993 in the "Production of Control System Function Table Diagram".
(2) All electrical components and wires should be marked with letter symbols and wiring numbers that differ from those in the schematic diagram of the electrical circuit. The catalog number, terminal number and transmission line number of the circuit schematic diagram should be respectively applicable to GB5094-1985 electrical technology engineering code, GB4026-1992 electronic equipment terminal and special wire terminal digital code and GB4884-1985 wire identification.
(3) Different from the schematic diagram of the electrical circuit, each part of the same electrical product component (circuit breaker, electromagnetic coil, etc.) must be drawn together on the wiring diagram;
(4) The electrical wiring diagram is drawn with a fine wire frame. The wiring method is divided into two kinds of pre-board wiring and post-board wiring, generally using pre-board wiring, for the simple electrical control system, the total number of electrical product components is less, and the wiring is not cumbersome, and the connection between the components can be made immediately; In view of the redundant components, the total number of electrical product components is large, and the wiring is more complicated, the wire duct is generally selected, and the wiring number is indicated on the components of each electrical product, and there is no need to make the connection between the components.
(5) The wiring diagram should indicate the type standard, standard type, cross-section and color rules of various transmission lines used for wiring.
(6) When the components are connected with the external circuit, the RF connector should be used for the incoming and outgoing lines of the large cross-section transmission line, and the others should be connected through the terminal in the row.

Precautions for the use of Delixi leakage protector
1. If the two branch lines are connected, the current in the zero line flows to each other, which destroys the operating current balance in the zero sequence current transformer and causes the leakage maintainer to malfunction. If you want to use the neutral line of the power branch line as the neutral line of the lighting branch line nearby, it will cause the leakage of the power branch line.

Delixi circuit breaker operation failure
Operation failure is manifested by the dragging or misoperation of the circuit breaker. Because the most basic and important function of the high-voltage circuit breaker is to operate correctly and remove the fault of the power grid quickly. If the circuit breaker drags or malfunctions, it will pose a serious threat to the power grid, first of all: (1)) expand the scale of the incident, which may make the original ...
