TS series 12/0.4 fully insulated desktop substation

Substation products are an indispensable and important component of the power system. They mainly play a role in distributing electrical energy, regulating voltage, protecting the safety of the power grid, and improving the quality of power supply. At the same time, they are also one of the devices that cause energy loss in the power grid. The composition of a substation determines its electrical safety and operational reliability, while energy consumption is a crucial issue that the power supply system urgently needs to address. Our company has independently developed a modular integrated combination low loss, fully insulated desktop substation that is convenient for construction personnel to install and maintain, in response to the extremely inconvenient maintenance of the flat 8 detection box for overhead transformers, as well as the risk of electric shock accidents caused by exposed high and low voltage cables.

The fully insulated desktop substation produced by our company is scientifically designed, reasonable, creative, compact in size, with monitoring and display instruments installed on one side for easy maintenance and operation, reducing energy consumption, easy installation, strong economic applicability, stable and reliable, and has good development prospects.

Product features

Each part of the fully insulated desktop substation adopts a modular installation method, and each unit can be separated and replaced.

The high and low voltage leads adopt a bus duct method, without exposed cables, with a smooth and simple appearance.

The fully insulated transformer adopts S11 and above oil immersed transformers, and the high-voltage incoming line is equipped with fully insulated cable heads, without exposed live parts, ensuring safety and reliability. The low-voltage side is installed together with a low-voltage bushing and a combination transformer, and there are maintenance doors installed on the high and low sides to facilitate the installation and maintenance of construction personnel.

The low-voltage load control box and low-voltage output compensation box are installed below the platform for easy observation and maintenance.

The traditional structure of substation has been abolished, and the fully insulated desktop substation adopts a side near line structure. The high-voltage side adopts fully insulated cable heads, and the low-voltage side outgoing lines are encapsulated without exposed live bodies.

The rack of the fully insulated desktop substation is made of new metal materials, which are corrosion-resistant, environmentally friendly, and aesthetically pleasing.

The low-voltage bushing on the low-voltage side is installed together with the combined current transformer for easy installation and maintenance. The fully insulated desktop substation can be replaced as a whole. Currently, there are no other manufacturers producing it domestically or internationally.

The oil temperature gauge, oil level gauge, pressure relief valve and other gauges are installed in the high-pressure side protection box, and the tap changer is also installed in the high-pressure side protection box for easy and safe operation.

Product structure description

Fully insulated desktop substation, including stand, high-voltage protection box, low-voltage protection box, fully insulated transformer, low-voltage negative control box, and low-voltage output compensation box; The rack is installed between two electrical pillars, and the fully insulated transformer mentioned above is located on the rack. One side of the fully insulated transformer is equipped with a high-voltage protection box, and the other side of the fully insulated transformer is equipped with a low-voltage protection box; The lower part of the platform is equipped with a cable interlayer, which is connected to the platform as a whole. The cables are located inside the interlayer and there are no exposed charged bodies; The bottom end faces of the platform are connected to the low-voltage negative control box and the low-voltage output compensation box with detachable tight rings. High voltage cable trays and low voltage cable trays are respectively set on the two electrical columns.
