High voltage disconnector handcart is a kind of equipment used in high voltage power system, mainly used to disconnect the circuit to ensure the safe operation of the power system. This paper will introduce the working principle of high voltage disconnector handcart.
The high pressure disconnector handcart is composed of disconnecting knife, handle, transmission mechanism, bracket and other parts. The disconnecting knife is the core component of this handcart, and it is used for disconnecting the circuit. The disconnecting knives are usually made of copper and have good electrical conductivity and corrosion resistance. The handle is used to control the switch of the knife, and the transmission mechanism is to transfer the power of the handle to it, so that it can perform switching operation. The bracket is used to support the parts of the disconnecting knife and the transmission mechanism.
The working principle of the high voltage disconnecting handcart is to control the switch of the disconnecting knife through the handle, so as to realize the isolation of the circuit. When the handle is closed, the disconnecting knife is connected to the circuit, and the current can pass through normally. When the circuit needs to be isolated, the operator rotates the handle to isolate the disconnecting knife from the circuit, thus achieving the isolation of the circuit. When isolating the circuit, it is necessary to ensure that the distance between the disconnecting knife and the circuit is large enough to avoid the generation of electric arcs.
The use of high voltage disconnector handcart needs to pay attention to the following points:
1. Before use, it is necessary to check whether the disconnecting knife and transmission mechanism are normal to ensure the safety of the equipment.
2. Keep the handle stable during operation to avoid device damage or personal injury caused by sudden rotation of the handle.
3. When isolating the circuit, it is necessary to ensure that the distance between the disconnecting knife and the circuit is large enough to avoid the generation of arc.
4. It is necessary to clean and maintain the equipment after use to ensure the long-term use of the equipment.
High voltage disconnector handcart is a very important equipment, which can ensure the safe operation of the power system. It is necessary to pay attention to safety when using the equipment and follow the operation rules to ensure the normal operation of the equipment and the safety of personnel.
