Container fire protection measures

The important thing about the fire protection principle of the container is the material it is made of. The non-flammable foam color steel plate is used, which has quite good flame-retardant performance. The material itself does not produce toxic gas and is very safe to use.

Prefabricated cabin smart substation is about to enter the equipment installation stage

The prefabricated substation realizes the organic combination of electrical equipment and prefabricated cabin equipment. It adopts the integrated distribution and transportation of cabins, and at the same time achieves safe and standardized station construction, reduces the amount of on-site construction, and meets the requirements of rapid station construction. This mode is cost-effective in time and civil construction. It has obvious advantages in terms of construction volume.

Causes and countermeasures of over-voltage phenomena in box-type substations

These two kinds of overvoltages of the transformer are transient processes with short acting time. The operating overvoltage of the relay protection calibrator is generally 3.0 to 4.5 times the rated voltage, while the atmospheric overvoltage value is very high, up to 8-12 times the rated voltage, and the voltage distribution in the winding is extremely uneven. Part of the turns are subject to high voltages. Therefore, necessary measures must be taken to prevent the occurrence of overvoltage and carry out effective protection.

The box-type substation manufacturer tells you how to choose the box of the 35kv box-type substation

According to the structure of box-type substation, manufacturers of box-type substation mainly include American box-type substation and European-type box-type substation. European-style box-type substations are low in cost, and American box-type substations are small in size, about 1.3-1.5 of that of European-style box-type substations with the same capacity. The traditional civil substation covers the largest area, followed by the European-style box-type substation.
