Maintenance folding editor .1. Disconnect the power and check the control rack cabinet whether this paragraph, reliable grounding, and the grounding resistance of less than 4Ω. Maintenance folding Edit this paragraph (1) Disconnect the power and check the control cabinet Is there a reliable chassis ground, and grounding resistance of less than 4Ω 2. voltage control cabinet have different properties. (DC 110V; AC single phase 220V; three-phase AC), when maintenance must distinguish circuit to prevent short circuits The accident maintenance folded Edit this paragraph .1 disconnect the power and check the control cabinet rack is a reliable ground, and grounding resistance of less than 4Ω 2. There are different types of control cabinet voltage (DC 110V;.. AC single phase 220V;. three-phase AC), when maintenance must distinguish circuit to prevent short circuit accidents 3. The control cabinet all electrical switches, should be flexible and reliable, no significant noise, cables knots and terminal should be no loose phenomenon, moving contacts at the wire cable knot should be no breakage. 4. Use a soft brush or hair clear panel plug-ins and all parts of the electromagnetic switch dust, and check the control cabinet electrical switch contact status, exposure action coil outer insulation and mechanical parts is reliable. 5. Replace the fuse should be blown to the loop current and the current match. The basic role of the control cabinet collapsed edit this section control cabinet is mainly used in high-rise buildings without water tower, fire deep well pump constant pressure water supply adjusted according to real-time closed-loop water pump speed conditions necessary occasions, using well-known brands of inverter, intelligent controllers, pressure sensors and closed-loop control system water pump. Multi-pump control, pipe network pressure stability, improve water quality, reduce secondary pollution, high energy-saving efficiency can be achieved without water tower unattended automatic control system. Control cabinet also includes many kinds of electrical control cabinet, frequency control cabinet, low voltage control cabinet, high voltage control cabinet, pump control cabinet, power control cabinet, explosion-proof control cabinet, elevator control cabinet, PLC control cabinet, fire control cabinet, brick control cabinet and so on. Maintenance folding Edit this paragraph (1) Disconnect the power and check the control cabinet rack is a reliable grounding, and the grounding resistance of less than 4Ω 2.

The control cabinet all electrical switches, should be flexible and reliable, no significant noise, cables knots and terminal should be no loosening. moving contacts at the wire cable knot should be no breakage. 4. Use a soft brush or hair clear dust panel plug-ins and all parts of the electromagnetic switch, control cabinet and check the status of electrical switch contacts, the contact, the coil action appearance insulation and mechanical parts is reliable. 5. Replace the fuse, should make fusing current and the current of the circuit to match. The basic role of the control cabinet collapsed edit this section control cabinet is mainly used in high-rise building water tower , fire deep well pump constant pressure water supply based on real-time closed-loop water conditions necessary adjust the pump speed of the occasion, the use of well-known brands of inverter, intelligent controllers, pressure sensors and closed-loop control system water pump. Multi-pump control, pipe network pressure stability, improve water quality, reduce secondary pollution, high energy-saving efficiency can be achieved without water tower unattended automatic control system. Control cabinet also includes many kinds of electrical control cabinet, frequency control cabinet, low voltage control cabinet, high voltage control cabinet, pump control cabinet, power control cabinet, explosion-proof control cabinet, elevator control cabinet, PLC control cabinet, fire control cabinet, brick control cabinet and so on. 3.
