What are the precautions for the connection of Volvo diesel generator set wire?

The connection of the power line of the output of the diesel generator set to the load should be carried out by a qualified electrician with extensive experience, as well as repair and maintenance. In addition, the wiring of the unit must meet the relevant electrical standards or other requirements, including grounding and grounding fault protection requirements. The following is a detailed introduction by Bo Rui Xiaobian to the connection of the diesel generator wire matters needing attention.

a.Wiring:

Due to the vibration of the generator, the generator should be connected with a soft wire, so that when the generator displacement will not damage the AC generator or the connecting column of the power supply air switch, such as the installation problem can not use the soft wire, can be installed near the generator a junction box, from the box to the machine for a section of the soft wire connection. The wire shall be placed on the pipe or the wire roughness and shall not be fixed on the generator set. If the wire needs to be bent, please refer to the minimum bending radius.

The wire must match the voltage and current output of the generator. Before deciding the thickness of the wire, you need to consider the temperature of the room, the method of installation and other wires in the side by side. When using single-core copper wire, the sealing sheath should be made of non-magnetic metal such as aluminum or copper, or non-metallic metal such as Teflon. In the case of magnetic metal sheathing, the smart method cuts gaps in the sheathing to ensure that the current does not create eddy currents.

Dongguan Borui Mechanical and Electrical Engineering Co., Ltd. reminds you that all interfaces must be checked for firmness. Whether the phase is the same as the mains, this is particularly important when using an automatic switch or when the unit is used for parallel running.

b.protection

Connected generator and load by the circuit breaker to protect, in overload or short circuit automatically off the circuit.

c.Load

When designing the power supply system to ensure the load balance, do not load one phase far more than the other phase, this will cause the alternator coil overheating. Phase and phase imbalance may also damage the sensitive three-phase equipment connected to the electrical system. Make sure that the current of the first phase does not exceed the current of the generator. If it is necessary to connect units to existing supply branches, reallocation must be considered so that these loads are balanced.

d.Power factor

The power factor (COS) of the load must be calculated in the design. For example, if the power factor is less than 0.8, the lag (inductance) will overload the generator. The most smooth running power factor of the output power of the machine is 0.8-1.

Special care should be taken to avoid power factor lead when installing automatic or manual power factor correction devices such as capacitors. This will lead to voltage instability and destructive ultra-high voltage. In general, all power factor correctors should be turned off while the generator is supplying power.

Jiangsu Meao Power Technology Co., Ltd. is an important manufacturer of diesel generators. The company mainly manufactures and sells diesel generator sets with power of 3-3000kW, mobile power station of 24-600kW, Marine emergency diesel generator set of 24-800kW, gas generator set, heavy oil generator set and all kinds of imported series, special series (trailer, static speaker, mobile lighthouse, container, etc.) diesel generator At the same time, we are engaged in generator set maintenance and after-sale service of generator set accessories.
