Non metallic box type substations have the following characteristics: 1. Good insulation performance: Non metallic materials usually have good insulation properties, which can effectively reduce the risk of electric shock, improve the safety of substation operation, and reduce safety accidents caused by leakage and other issues. This is of great significance for ensuring the safety of surr
1. Protective performance Mechanical protection: The substation casing can provide mechanical protection for internal equipment. It can withstand a certain degree of external impact, such as collisions with small objects, wind loads, snow loads, etc. For example, in outdoor substations, the casing can withstand the impact of tree branches, sand, and other objects in strong wind weather, pr
The application of the shell of the imitation stone brick box type substation in industrial parks mainly includes the following aspects: 1.Aesthetic and environmental harmony: Enhancing the landscape of industrial parks: Industrial parks usually have relatively unified planning and appearance requirements. The shell of the imitation stone brick box type substation can mimic the texture, co
Non tiled ultra wide non-metallic shells can be applied in the following scenarios: 1. In the field of power facilities: Box type substation shell: In outdoor box type substations, non-metallic shells are widely used as shells. This type of casing can provide good protection for internal electrical equipment, preventing external dust, moisture, small animals, etc. from entering, ensuring
The operation of power failure shall follow the sequence of switch, load side knife switch and power side knife switch, and the switching operation of power transmission shall follow the reverse sequence of the above, and it is strictly prohibited to pull and close the knife switch with load.
Due to the complex internal structure of the box transformer and the large number of power distribution devices, special care must be taken in the normal operation and maintenance.
Five prevention: short for prevention of electrical misoperation, namely prevention of false opening and closing of circuit breakers; Prevent the handcart isolation plug of the metal enclosed (armored) switch cabinet from being pushed in and pulled out with the load opening and closing disconnectors or with the load; Prevent the electrified grounding wire from hanging or closing the grounding swit
In short, if low-quality wires are used, it will produce: 1. The wires are very hot; 2. The insulation is prone to breakdown or premature aging, resulting in electric leakage; 3. Large power consumption; 4. It is easy to cause fire and cause heavy casualties.
