Problems solved by technology

The 40.5KV high-voltage inflatable cabinet has always been a vacancy. The main reason is that the protective plate adapted to the high-voltage inflatable cabinet needs to withstand high voltage. The high voltage of the 40.5KV inflatable cabinet is 98,000 volts, and the partial discharge can reach below 0.1, while the high-voltage resistant 40.5KV Composite materials are still a vacancy in the market at this stage

Embodiment 1

[0014] A composite material for a high-pressure resistant protective plate, which is composed of glass fiber mat and RTM unsaturated resin, and the weight ratio of the glass fiber mat and RTM unsaturated resin is 3:2.

[0015] The preparation method of the composite material for the above-mentioned high-voltage protective plate, the specific steps are as follows:

[0016] (1) Obtain glass fiber felt and RTM unsaturated resin by recipe amount for subsequent use;

[0017] (2) After mixing glass fiber felt and RTM unsaturated resin, it is molded under the condition of 130°C to obtain the product. The obtained composite material has passed the tracking resistance test (refer to "GB / T 4207-2007 Measurement Method for Comparative Tracking Index and Tracking Resistance Index of Solid Insulating Materials under Humid Conditions"), and the 5 test points can withstand Hold 70 drops of solution without forming a 0.5A conductive path, and have outstanding tracking resistance.

Abstract

The invention provides a composite material for a high-pressure-resistant protective plate. The composite material is prepared from glass fiber felt and RTM unsaturated polyester resin, a weight ratioof the glass fiber felt to the RTM unsaturated polyester resin is 3: (1 to 3), and the composite material is obtained by mixing the glass fiber felt and the RTM unsaturated polyester resin and then die pressing and molding the mixture at 130 DEG C. The composite material has excellent characteristics such as creepage resistance and high voltage resistance, plays a critical role in promoting the high-voltage switch market in future, and can meet the large-scale industrial production requirement.

Description

technical field [0001] The invention relates to the production field of high-voltage protective plates, in particular to a composite material used for high-voltage protective plates. Background technique [0002] At present, the high-voltage inflatable cabinets in the domestic market are 12KV and 24KV. The 40.5KV high-voltage inflatable cabinet has always been a vacancy. The main reason is that the protective plate adapted to the high-voltage inflatable cabinet needs to withstand high voltage. The high voltage of the 40.5KV inflatable cabinet is 98,000 volts, and the partial discharge can reach below 0.1, while the high-voltage resistant 40.5KV Composite materials are still a vacancy in the market at this stage. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a composite material used for a high-voltage protective plate. [0004] In order to solve the problems of the technologies described above, the technical ...
