Embodiment 1

[0061] Please refer to Figure 1 to Figure 8 , figure 1 It is a partial structural schematic diagram of the anti-condensation ring main unit of the present invention. The anti-condensation ring network cabinet of this embodiment includes a cabinet body 1, and an inlet hole 110 is arranged on the bottom plate of the cabinet body 1, and the wire inlet cable 5 is introduced into the cabinet body 1 through the wire inlet hole 110, and is sequentially connected with the terminal , in order to facilitate installation, there is a large gap between the incoming cable 5 and the incoming hole 110, the size of this gap is generally 10-20mm, and the water vapor in the cable pit enters the channel of the cabinet body 1, and the water vapor It is the main source of moisture for condensation.

[0062] The structure of this embodiment is: a first component for blocking, a second component, and a sealing layer 4 filled between the first component and the second component are arranged around ...

Embodiment 2

[0077] In the present embodiment, the manufacturing method of the ring network cabinet with a sealed structure includes the following specific steps:

[0078] Step S101, making the bottom plate of the cabinet body 1, stamping the flat plate made of alloy steel, and grinding the matching contact surface 121 of the stopper protrusion 120 to ensure that the roughness is Ra0.8;

[0079] Step S102, making the sealing plate 3, measuring its diameter according to the inner ring formed by the stop protrusion 120, the diameter of the sealing plate 3 is less than the diameter of the inner ring 2 mm, and welding a semicircle with a radius of 2 mm on the upper surface of the sealing plate 3 Shaped convex rib 310;

[0080] Step S103, making the housing 2, measuring its diameter according to the outer ring formed by the stop protrusion 120, the minimum inner diameter of the housing 2 is consistent with the diameter of the outer ring, and the third section 230 of the housing 2 The inner mou...

Embodiment 3

[0085] In this embodiment, the manufacturing method of the ring network cabinet with a sealed structure includes the following specific steps:

[0086] Step S101, making the bottom plate of the cabinet body 1, stamping a flat plate made of alloy steel, wherein the mating contact surface 121 of the stopper protrusion 120 is polished to ensure that the roughness of the mating contact surface 121 is Ra1.6;

Abstract

The invention discloses an anti-condensation ring main unit, a manufacturing method thereof and a power distribution system, and belongs to the technical field of intelligent electrical equipment. Thering main unit comprises a unit body, a first component, a second component and a seal layer, wherein a wire inlet is formed in a bottom plate of the unit body, the first component and the second component surround the wire inlet and are used for blocking, and the portion between the first component and the second component is filled with the seal layer. The first component, the second componentand the seal layer are used for sealing the gap between an incoming cable and the wire inlet instead of additionally arranging an intelligent dehumidifying device, production cost is saved, installation of the incoming cable is not affected, steam entering the unit body is isolated from the source, the humidity in the unit body is reduced, the steam condensation phenomenon in the ring main unit isreduced, components and parts in the ring main unit are effectively protected from damage, and normal work of the ring main unit is ensured.

Description

technical field [0001] The invention belongs to the technical field of intelligent power equipment, and more specifically relates to an anti-condensation ring network cabinet, a manufacturing method thereof, and a power distribution system. Background technique [0002] The ring network cabinet is a group of transmission and distribution electrical equipment (high-voltage switchgear) installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses, and its power supply The main line forms a closed ring, and the power supply supplies power to this ring main line, and then distributes power from the main line through high-voltage switches one by one. Each power distribution branch can take power from the left main line of the ring network, and can also The power supply is taken from the right main line of the ring network. When the left main line fails, the ring network will contin...
