As the name suggests, the power supply system is used in power distribution, control, measurement, and connecting cable power distribution equipment in the power supply system. Generally, the power supply bureau and the substation are used at a high voltage switch, and then the transformer lower voltage and low voltage side side sideLeading to the low -voltage power distribution cabinet, the low -voltage power distribution cabinet to the power distribution disk, control box, switch box of each electric use, inside the protection devices such as switching, circuit breakers, fuses, buttons, indicators, instruments, electric wires, etc.Equipment assembled into a power distribution device with design function requirements.
Price of high and low voltage power distribution cabinet
Haitan GGD high and low voltage power distribution cabinet: This high and low voltage power distribution cabinet belongs to the Haitan brand. Its lock core material uses zinc alloy material.Its center distance is 50 mm. The color of the decorative surface is divided into two types: black and matte. The direction of opening the door is universal.Under normal circumstances, the thickness of the door adapted is within 35 mm, and the distance of the lock edge is 45 mm. From a security perspective, it can completely prevent short circuit or grounding.In the process of use, the insulation tool should be used, as well as wearing insulating gloves, and its market sales price is 525 yuan.Siemens KYN28A-12 high and low voltage power distribution box: This high and low voltage power distribution box belongs to the Siemens brand, which is generally used in indoor.During the use of use, no operations and wires formed between short -circuit terminals and current transformers can be performed on each other.In the case of temporary loads, dedicated switches and fuses must be equipped.Generally, this high and low voltage distribution box has two series, one is the 63 series, and the other is the MB series.The material on the subject is made of metal. The weight of the product is 9.5 kg. Its market sales price is generally 539 yuan.
Design of high and low voltage power distribution cabinet
Electrical selection criteria.The electrical appliances selected in the design of the low -voltage distribution box should meet the current national standards.First of all, select the rated voltage of the electrical appliances to adapt to the frequency of the loop. Secondly, the rated current of the electrical appliance is greater than the internal current of the loop.The electrical appliances should be suitable for the environmental conditions of the workplace. Finally, select the electrical appliances under short -circuit conditions to meet the requirements of dynamic stability and thermal stability. The electrical appliances that disconnect the short -circuit current should have the ability to break under short circuit conditions.
High and low voltage power distribution cabinet use
The high -voltage switch cabinet is a high -voltage power distribution assembly assembled by a certain wiring solution.Among them, high -voltage switching equipment is equipped with high -voltage switching equipment, protecting electrical appliances, inspection and determining instruments, mother lines, insulators, etc.High -voltage switch cabinets have two categories: fixed and hand car types. Generally, most of the change in small and medium -sized factories use more economical fixed high -voltage cabinets.The uniqueness of the hand -to -type switch cabinet is that the primary devices such as high -voltage circuit breakers are installed on a hand car that can be pulled out.When the device is checked and repaired, when it is pulled out and pushed into a similar hand car, the power supply can be restored. It has the advantages of inspection and repair benefits and safety, and greatly shorten the advantages of the power outage time.

Principle of high and low voltage power distribution cabinet
Sensory loads need to absorb the power and non -power current operation of the power grid, so that the power grid increases the transmission of non -effective current, and the loss of the power grid cable increases.The capacitor cabinet consumes a proper powerless current to automatically use the volume of the capacitors to automatically invest in unpaid current input according to the line perceptual load, thereby increasing the power factor of the line.
