Embodiment 1

[0032] Such as figure 1 As shown, the integrated plug-and-play secondary equipment component structure of the intelligent substation includes a secondary equipment prefabricated cabin 1, a prefabricated optical cable 2, an on-site control cabinet 3, and a prefabricated cable 4. A plug-and-play connection between the local control cabinets 3 is achieved through the prefabricated optical cable 2, and the prefabricated cable 4 is used for the plug-and-play connection between the local control cabinet 3 and the primary equipment 5 of the substation.

[0033] The internal chamber of the secondary equipment prefabricated cabin 1 is divided from top to bottom by two transverse load-bearing plates 6 into a secondary equipment area 7 at the station control layer, a secondary equipment area 8 at the partition layer, and a wiring area 9 The lateral bearing plate 6 and the inner wall of the secondary equipment prefabricated cabin 1 are supported and fixed by a plurality of vertical support p...

Embodiment 2

[0041] The difference from Example 1 is that: the outer surfaces of the prefabricated secondary equipment cabin and the on-site control cabinet are both coated with a dense coating with paint, which is prepared by the following parts by weight: the suspension agent includes Kaolin and vermiculite powder, the weight ratio of kaolin: vermiculite powder is 6:1, and the particle size of kaolin and vermiculite powder is 200 mesh. The binder is polyvinyl alcohol resin. The additives include nonylphenol polyoxyethylene ether, p-toluenesulfonic acid, and polyimide, and the weight ratio of nonylphenol polyoxyethylene ether: p-toluenesulfonic acid: polyimide is 1:2.5:3.5.

[0042] The preparation method of the coating includes the following steps:

[0043] S1: After mixing the binder and 10 parts by weight of water, place it in a reaction kettle at a temperature of 85°C, a speed of 200r / min, and stirring for 20 minutes;

[0044] S2: After the temperature in the reactor in step S1 drops to 20...

Embodiment 3

[0048] The difference from Example 2 is that the outer surfaces of the prefabricated secondary equipment cabin and the on-site control cabinet are both coated with a dense coating with paint, which is prepared from the following components by weight: Kaolin and vermiculite powder, the weight ratio of kaolin: vermiculite powder is 7:1, and the particle size of kaolin and vermiculite powder is 250 mesh. The binder is polyvinyl alcohol resin. The additives include nonylphenol polyoxyethylene ether, p-toluenesulfonic acid, and polyimide, and the weight ratio of nonylphenol polyoxyethylene ether: p-toluenesulfonic acid: polyimide is 1:2.5:3.5.

[0049] The preparation method of the coating is the same as in Example 2.

Abstract

The invention discloses a whole station plug-and-play secondary equipment component structure of an intelligent substation. The whole station plug-and-play secondary equipment component structure comprises a secondary equipment prefabricated cabin, a prefabricated optical cable, a local control cabinet and a prefabricated cable, wherein a plug-and-play connection between the secondary equipment prefabricated cabinet and the local control cabinet is realized through the prefabricated optical cable; the prefabricated optical cable is used for realizing a plug-and-play connection between the local control cabinet and substation primary equipment; the interior chamber of the secondary equipment prefabricated cabin is divided into a station control layer secondary equipment area, a spacer layersecondary equipment area and a coil line area from top to bottom through two lateral load-bearing plates; a plurality of vertical support plates are arranged in parallel between the two lateral load-bearing plates and an inner wall of the secondary equipment prefabricated cabin; process layer secondary equipment is arranged inside the local control cabinet; the process layer secondary equipment comprises a merging unit and an intelligent terminal; the merging unit is used for acquiring voltage and current information of the primary equipment; and the intelligent terminal is used for acquiringposition and alarm information of the primary equipment. The whole station plug-and-play secondary equipment component structure has the advantages of flexible layout, function partition as well as plug and play.

Description

Technical field [0001] The invention belongs to the technical field of substation secondary equipment, and in particular relates to a plug-and-play secondary equipment component structure of an intelligent substation complete station. Background technique [0002] At present, the configuration of secondary equipment in smart substations mainly adopts a hierarchical distributed structure, which is interval-oriented and functions independent. The secondary equipment of each bay is centrally arranged in the main control relay room, and is connected to the power distribution device area of ​​the primary equipment through cables and optical cables to complete the protection, measurement and control, and metering functions of each bay. During the construction phase of the substation, each secondary equipment manufacturer transports their respective secondary screen cabinets to the construction site, and then installs and connects them by the construction unit. After the installation i...
