1. No matter what kind of electrical equipment it is, the power cord must be guaranteed to be intact and must not be damaged. Once it is found to be damaged, it cannot be used again, and it needs to be repaired before use to ensure safety.

2. Regularly inspect the electrical equipment, pay attention to see whether there is a disconnection phenomenon according to the ground setting, and it should also be repaired in time, otherwise it is easy to affect the safe use, and there is a possibility of electric shock in serious cases.

3. When pulling the switch of electrical equipment, the operator needs to wear the necessary safety protection equipment, and the action of pulling the light must be fast, and the face must be able to dodge in time, so as to avoid some troubles.

4. For the motor of electrical equipment, it is also necessary to check whether its temperature will be too high. Note that at this time, you need to touch the motor with the back of your hand, not with the palm of your hand, so as not to suck it and not be able to disconnect.

5. If you are not very familiar with the electric dust stove gas equipment, it is strictly forbidden to use automatic electrical equipment, and you cannot repair it without authorization. In the daily cleaning of electrical equipment, it is not allowed to wipe with a damp cloth, let alone flush directly with water, which will cause damage.

Summary. Electrical equipment consists of power supplies, circuits, controllers, sensors, interfaces, displays, operators, safety devices, etc. A power supply is a device that provides electrical energy, which can be a battery, a generator, a transformer, etc.; The circuit is the core of electrical equipment, which is composed of resistors, capacitors, inductors, switches, transformers, interfaces, etc.; The controller is the core of electrical equipment, which can control the operation of electrical equipment; The sensor is an important part of electrical equipment, which can detect the operating status of electrical equipment; The interface is an important part of the electrical equipment, which can connect the various parts of the electrical equipment; The display is an important part of electrical equipment, which can show the operating status of electrical equipment; The operator is an important part of electrical equipment, which can control the operation of electrical equipment; Safety devices are an important part of electrical equipment, which can protect the safe operation of electrical equipment.

Fellow, I really didn't understand, I can be more specific.

Electrical equipment is composed of power supply, controller, motor, transmission mechanism, junction box, contactor, relay, button, switch, indicator light, etc. Problems may occur due to faults in controllers, motors, transmission mechanisms, etc. of electrical equipment, or due to faults in junction boxes, contactors, relays, buttons, switches, indicator lights, etc. Workaround:

1.First of all, you should check the controller, motor, transmission mechanism, etc. of the electrical equipment to see if there is a fault. 2.

Secondly, the junction box, contactor, relay, button, switch, indicator light, etc. should be checked to see if there is a fault, and if there is, it should be repaired or replaced in time. 3.Finally, the power supply should be inspected to see if there is a fault, and if so, it should be repaired or replaced in time.

Personal Tips:1When using electrical equipment, it should be checked regularly, problems should be found in time, and repaired or replaced in time to avoid unnecessary losses.

2.When using electrical equipment, you should pay attention to safety and do not disassemble or replace electrical equipment without authorization, so as not to cause irreparable losses. 3.

When using electrical equipment, attention should be paid to keeping the electrical equipment clean so as not to affect the normal use of the electrical equipment.
