Safety precautions for power connection of stage electric hoist
1、 Choose the appropriate power source
Before connecting to power, the first step is to choose a suitable power source. When choosing a power source, it is important to ensure that the capacity of the power source is large enough to meet the power requirements of the stage electric hoist. At the same time, it is necessary to check the grounding of the power supply to ensure good grounding and prevent electrical accidents from occurring.
2、 Use qualified wires and sockets
During the power connection process, qualified wires and sockets should be used. The cross-sectional area of the wire should be large enough to withstand the current demand of the stage electric hoist. At the same time, it is necessary to choose wires with good quality and insulation performance to prevent wire short circuits or leakage. The socket should choose a three-phase socket that meets national standards and ensure good contact to prevent electrical accidents caused by poor contact.
3、 Correct wiring
During the power connection process, it is necessary to wire the wires correctly. Firstly, it is necessary to determine the wiring method of the motor according to the instructions of the stage electric hoist. Generally speaking, there are two types of motors for stage electric hoists: star connection and triangle connection. When wiring, ensure that the motor is wired correctly, otherwise it may cause the motor to malfunction and even burn out. Secondly, it is necessary to ensure that the joints of the wires are firm and reliable to prevent electrical accidents caused by loose joints.
4、 Install leakage protector
To ensure electrical safety, it is recommended to install a leakage protector on the power line of the stage electric hoist. Leakage protectors can quickly cut off power in the event of a leakage accident, protecting the lives of workers and spectators. When installing a leakage protector, it is necessary to ensure that the rated current and operating time of the leakage protector meet the requirements of the stage electric hoist.
5、 Grounding protection
The shell of the stage electric hoist must be grounded to prevent electrical accidents caused by the shell being electrified. When grounding, use grounding wires that comply with national standards. At the same time, it is necessary to regularly check the grounding situation to ensure good grounding.
6、 Avoid overload and short circuit
When using stage electric hoists, it is important to avoid overloading and short circuits. Overload and short circuit can cause excessive current, burn motors and wires, and lead to electrical accidents. Therefore, when using stage electric hoists, it is necessary to choose suitable electric hoists based on the weight of stage props and equipment, and avoid overloading. At the same time, it is necessary to regularly check the contact between wires and sockets to ensure good contact and prevent short circuit accidents from occurring.
7、 Professional personnel operation
The power connection of the stage electric hoist must be operated by professional personnel. Professional personnel have rich electrical knowledge and experience, which can ensure the safety and correctness of electrical work. During the power on process, professionals must strictly follow electrical safety operating procedures and use tools and equipment that comply with national standards.
