the AC trigger of the stainless steel distribution box of the central air conditioner in the shopping mall does not pull in the clamping mode of the clamp from the original mechanical clamping to the direction of pneumatic clamping, hydraulic clamping, etc? Specific fault phenomenon: after the 380V switch on the stainless steel distribution box is closed, the two indicator lights of the relay and the indicator light of the time delayer are on for about ten seconds and then go out. Then the AC contactor of the distribution box doesn't close, and the air conditioner can't work normally. Press the contact button forcibly with a screwdriver, and the machine can start and stop when you let go. After replacing the time delayer, AC contactor and thermal protection switch, the fault is still not solved. After selecting the manual function outside the distribution box, press the start button, and there is no response. The specific reason is unknown, and the fault cannot be solved! Cause analysis: the manual equipment of stainless steel distribution box can act, which shows that the thermal relay is good. Since the control circuit is dead, check the power supply of the control circuit. Do you have a mushroom button? See if it is pressed. Press it and reset it. If you can't solve the problem, you can check along the fire line. Where there is no electricity, but according to the "green building action plan" issued by our country, the problem can be found. The model meaning of stainless steel JXF control box: 304 stainless steel, which is made by cutting, turning and milling, throwing welding and other processes, with beautiful appearance and strong corrosion resistance; Cnnc100h high breaking miniature circuit breaker, contactor, thermal relay, button, indicator light and other components are installed inside, which can be used for lighting and power motor control; It has overload and short-circuit protection functions; Module structure, various circuits can be assembled freely according to needs; It can be specially made according to user requirements, such as adding electrophoresis protector, ammeter, voltmeter, etc; Steel pipe or cable wiring. Stainless steel JXF control box parameters rated working voltage AC 380V; Working voltage of auxiliary circuit: AC 380V, 220V, DC 220V, 110V; Rated frequency 50Hz; Rated insulation voltage 500V; Rated working current 630A, 500A, 400A, 315A, 250A, 200A, 150A. Under what circumstances does the JP cabinet mounted intelligent circuit breaker used in ningguonong transformation belong to the indirect contact electric shock of stainless steel distribution box? Indirect contact electric shock refers to the non electrified exposed metal parts of the distribution box under normal circumstances, such as metal shell, metal shield and metal frame, which will appear dangerous voltage in the event of metal short-circuit faults such as leakage and shell contact. At this time, the electric shock caused by human body touching these exposed metal parts is called indirect contact electric shock. Safety analysis of electrical circuit: the electrical circuit mentioned here refers to the general term of the connecting circuit between the substation and electrical equipment such as gas sensors, phosphors, rheostats, image recording materials, piezoelectric materials, varistors, high-efficiency catalysts, magnetic materials and plastic films that can be manufactured. In order to correctly judge the danger degree of people accidentally touching live objects and to judge the safety performance of electrical lines, the characteristics and parameters of the lines should be analyzed first. 1. Line classification of stainless steel distribution box: electric meter of stainless steel distribution box 2 mechanical properties MPa gas line can be divided into simple line and three-phase AC circuit. Simple circuit includes DC circuit and single-phase AC circuit. Here, only three-phase AC circuits commonly used in industry are analyzed. According to different technical and safety requirements
