After the busbar processing machine is used to punch holes, just turn the handle to the position of the oil return label. When using cut and bent rows, you can turn the reversing handle to the position marked with cut and bent rows. After use, remember to turn the handle to the position of the oil return label.

2. After the busbar bending machine is connected to the power supply, preheat the busbar processing machine for a short period of time, which will make the busbar processing machine more handy in the next operation.

Generally, the busbar processing machine stipulates that the contact resistance of the bolt connection point cannot be greater than the resistance of the busbar itself with the same length. Because the size and direction of the direct current do not change with time, so the constant direct current is passed into the primary winding, and the magnetic flux generated in the iron core is also constant, so the potential cannot be induced in the secondary winding, so it does not work as a voltage transformer.

     According to the number of conductors, there are three-phase four-wire system and three-phase five-wire system (independent PE row is added, and some manufacturers provide aluminum alloy shells as integral grounded PE forms). Incoming (outgoing) line units that interface with transformers, power distribution cabinets and other equipment; reversing units include L-shaped units, T-shaped units, and Z-shaped units; expansion units include expansion joint busbar units; plug-in units include plug-in box units. All units of the busbar processing machine are usually designed as standard by the busway manufacturer, and non-standard designs can also be adopted after on-site measurement according to engineering needs to meet user and installation needs. The busway system is generally used in the connection between the transformer and the power distribution cabinet, as well as the power supply system starting from the power distribution center (distribution panel, cabinet) to the load in the form of trunk wiring. The current level of the system is usually 250~5000A, the rated voltage is 400~1000V, and the protection level is IP40~IP65. The closed busway (referred to as the busway) is made of metal plates (steel plates or aluminum plates) as protective shells, conductive bars, insulating materials and related accessories. Composed busbar system. It can be made into a plug-in closed bus duct with plug-in junction boxes at intervals, or a feed-type closed bus duct without a junction box in the middle. In the power supply system of high-rise buildings, the power and lighting lines are often set separately, and the bus duct is installed vertically along the wall one or more times in the electrical shaft as the main power supply line. It is necessary to keep the working current of the motor of the busbar processing machine not too large. The motor is overloaded due to excessive load, low voltage or driven mechanical stagnation. Therefore, during the operation of the motor, it is necessary to pay attention to frequently checking whether the transmission device is flexible and reliable; whether the concentricity of the coupling is standard; the flexibility of the gear transmission, etc. .
1. Use high-quality hydraulic oil and meet the usage volume.

Choose the appropriate pressure according to the size of the busbar you use. Put them into the mold and test one by one, which is used for cutting, punching, flat bending and vertical bending of copper and aluminum busbars. There is a horizontal workbench, and the workbench is provided with a fixed mold base, a machine base with a guide, a hydraulic cylinder and a slide block that can slide on the machine base with a guide under the push of the hydraulic cylinder. Check whether the plug box pins of the busway system are in good contact with the busbar.

1. Before changing the mold, the punching unit mold needle should be taken out.

Tube busbar conductors are generally installed overhead after welding. After overhead, the tubular conductors are fixed with special tube busbar fittings. Since the strength of the joints is reduced after welding, in order to avoid bending of the joints after overhead, the inside of the joints The liner shall be used for reinforcement, and there shall not be more than two welding joints between two empty pillars. It is necessary to keep the working current of the motor of the busbar processing machine not too large. A voltage transformer is a special transformer with a limited structure and use form. The parameters of the punch mainly include the size of the working part, the size of the installation part, and the length.

Technical marketing innovation
Fasten the parts and check whether the fastening parts are loose or damaged. The method to be adopted is to find parts of the same specification for replacement. Because the NTC negative temperature coefficient thermistor has the advantages of stable performance, high sensitivity, good dynamic performance, and moderate price, it can meet the requirements of busbar temperature measurement in high-voltage environments. Therefore, the busbar processing machine uses NTC negative temperature coefficient thermistor as the first choice. sensing element. The larger the capacity of the transformer used now, the greater the impact on the power grid, and its safety is required to be higher and higher.
