First, outline
The gas insulation metal seal switching gear (Gas Insulated metal-enclosed Switchgear, is called GIS) is one kind of new electrical fittings which 20th century 60's intermediate stages appears. It is the circuit breaker, the isolator, the earthing switch, the current transformer, the voltage transformer, the arrester, the generatrix, enters unit construction seal and so on going beyond a line drive pipe or cable termination in the earth metal shell, imitates by the certain pressure SF6 gas took the insulation medium and the extinguishing of arc medium compose complete switching gear. Because it both seals up and combines, therefore occupying a land area of surface minimum, the environment influence, is not produced the noise and the radio jamming, the movement safe reliable also the maintenance work load are few, thus since has been published obtains has developed vigorously.
Second, product introduction
Model explanation that,the ZF16-252 combination electric appliance is Shandong extreme has the electrical limited company through after the domestic and foreign markets widespread investigation and study, unifies GIS the development direction, summarized has profited from the domestic and foreign GIS advanced design thought, development development new generation of GIS. Below this product has the characteristic:
1. The volume is small
Brand-new design miniaturized GIS, the gap width is 2.1m, the product volume compares the domestic product to reduce approximately 20%, has the structure compact, the contour is artistic, craft excellent, Is advantageous for the whole transportation and the installment, The scene installs the cycle to be short and so on the merit.
2. The reliability is high
2.1 circuit breakers match ABB Corporation HMB-4 hydraulic pressure spring organization
Uses ABB Corporation the optimized improvement HMB-4 second generation of hydraulic pressure spring organization, it overcame the tradition hydraulic gear efficiency to be low, shortcoming and so on Yi Shenyou, each main function part integration and the modulation, enable it to have the high versatility and the interchangeability, and did not have the pipeline energy to lose, enables the organization efficiency to achieve the maximization. This organization movement stable reliable, mechanical life 6, 000, the use maintenance work load are extremely few. This organization has reached above 30, 000 in the global movement product, according to the international big electrical network conference statistics, this organization failure rate is lower than other types by far the organization.
2.2 isolators and the earthing switch organization uses on company mature 126GIS the organization, this organization had 2, 000 Taiwan the movement experience, the operation is extremely reliable.
2.3 uses the import insulation
The circuit breaker and the isolator insulation pole uses Swiss AXICOM Corporation the insulation pole, this kind of insulation pole remarkable merit was the textile fiber circles the system to use the radial direction, axial as well as circled the system alternately and so on the many kinds of different angles and the method, therefore had the splendid machine capability; Uses bears the SF6 resolvent and chemistry performance inert epoxy resin soaks gathers the fragrant nylon enhancement material, used the capillarity principle to carry on the epoxy resin under the vacuum to soak, had guaranteed the material was completely moist, has avoided the air bubble and the needle eye existence, had the greatly strengthened electric strength, and had the weight light characteristic.
The trough type insulator uses in the import epoxy resin and Germany learns the company to pour the equipment, guarantees the best electrical specification and the machine capability.
