Embodiment 1
[0020] Embodiment 1: the manufacturing method of solid insulated bus bar, finished product such as figure 1 shown.
[0021] The first step: spray the processed conductor 3 and conductor 6. The sandblasting part is the part in the figure except that the two ends of the conductor 3 are used as plugs and the lower end of the conductor 6, and then remove Oil treatment, washing off the oil stains on the conductor 3 and conductor 6 during processing with detergent, and then fastening the conductor 3 and conductor 6 with bolts 4;
[0022] The second step: on the outside of the assembled conductor 3 and conductor 6, coat a layer of carbon black particles with a thickness of 0.5±0.1 mm and a weight ratio of about 10% with a particle size of 5-10 μm, 0.2% titanic acid Semi-conductive coating layer 1 composed of ester, 60% resin varnish binder, 24% xylene and 6% butanol, and then placed in an incubator at 120±5°C for preheating and curing for 40 minutes to make the conductor 3 and the ...
Embodiment 2
[0027] Embodiment 2: the manufacturing method of high-voltage outlet bushing, finished product such as figure 2 , image 3 shown.
[0028] The first step: Spray the processed conductor 2, the sandblasting part is the part except that the two ends of the conductor 2 are made into plugs in the figure, and then perform degreasing treatment, and wash away the conductor 2 with detergent. sticky oil stains;
[0029] Step 2: Coat a layer of carbon black particles with a particle size of 5-10 μm and 0.2% titanate with a thickness of 0.5±0.1 mm on the outer surface of the conductor 2 except for the two ends. , 60% resin varnish adhesive, 24% xylene and 6% butanol to form a semi-conductive coating layer 3, and then put it into an incubator with a temperature of 125±10°C to preheat and cure for 25 minutes to make the conductor 2 The internal and external temperature is uniform, and the semi-conductive coating layer 3 is dried and cured;
[0030] Step 3: Put the preheated and cured c...
Embodiment 3
[0034] Embodiment 3: the manufacturing method of circuit breaker pole, finished product such as Figure 4 shown.
[0035] The first step: Spray the processed conductive terminal 2. The sandblasting part is the part except the upper inner hole wall and the middle inner hole wall of the conductive terminal 2 in the figure, and then carry out degreasing treatment and wash with detergent. Remove the oil stains on the conductive terminal 2 during processing;
[0036] Step 2: Coat the outer surface of the conductive terminal 2 with a thickness of 0.5±0.1 mm, which is about 10% by weight of carbon black particles with a particle size of 5-10 μm, 0.2% titanate, and 60% resin varnish Adhesive, 24% xylene and 6% butanol are mixed to form a semiconductive coating layer 3, and then placed in an incubator with a temperature of 120±5°C for preheating and curing for 40 minutes to dry and solidify the semiconductive coating layer;
[0037] Step 3: Pre-install the conductive terminal 2 and t...
