Abstract
The invention relates to a production technology of a totally enclosed transformer obturator, which belongs to the field of electric appliances and is a new technology for replacing a method for producing a transformer insulator by casting epoxy resin. A die-casting process (shown in the attached figure) is used for processing the totally enclosed transformer obturator into a cylinder, cuboid or cleat shape according to the installation requirements, and unsaturated polyester glass fiber reinforced molding compounds and iron core wires are packaged into a die to be heated to the specified temperature for die-casting molding, thereby meeting the national standard requirements. The production technology of the invention has simple processes and short production cycle, saves the energy, reduces the consumption, improves the production environment, and is especially suitable for the current national policies of energy saving and emission reduction.
Description
The production technology of totally enclosed transformer obturator is applicable to the voltage transformer summation current transformer of various models below the 10KV of epoxy resin injecting method production, belongs to appliance field.Shown in Figure of description: the pouring technology flow chart of Fig. 1 prior art, Fig. 2 declares the process chart of patent.Manufacturing techniques available is that epoxy resin and quartz sand are mixed heating, stir, and method such as vacuumize is handled, and as the technological process of Fig. 1, plays the effect of a support integral, reaches the purpose of insulation.The patent of invention technical matters is simple, sees Fig. 2.The purpose of these innovation and creation is to reduce cost, and improves enterprise competitiveness, and is energy-saving and cost-reducing, improves operational environment, reduces air pollution.
Use the method, only need that raw material (the unsaturated polyester glass fibre reinforced mould plastic is called for short DMC) are put into the mould heating and pressurizing and promptly be shaped, be up to state standards withstand voltage 42KV, dielectric strength 2500M Ω.
This invention is increased the benefit in order that reduce cost, and two kinds of technology degree relatively, in Fig. 1 production process, heating has two kinds of schemes: one, large enterprise uses steam heated, establish boiler, pipeline and production, attendant and cast producers.The method production cycle is long, and from quartz sand is dried, technological process is pressed in the epoxy resin heating then, and stripping forming is dried again, needs 48 hours.Two, small business adopts Electric heating, and each link by technological process all needs tens kilowatts electric power.And the present invention adopts the plastics compressor, and mold heated to assigned temperature, is only needed 4-6KW, charging feedstock, and moulding in 15 minutes only needs two people operation.
Two kinds of technologies are compared, and the former, the latter only needs 15 minutes 48 hours production cycles, and the manpower energy consumption is can several 10 demultiplications few.
Reduce cost:
The existing market price, about 2.7 ten thousand yuan of epoxy resin, about 10,000 yuan of glass fibre reinforced mould plastic prices.
Environment purification reduces and pollutes.
In the production process of prior art, can distribute dense especially pernicious gas to the epoxy resin heating, the staff must put on breathing mask and just can operate, and environmental pollution is serious.No any pernicious gas in the new technology production process.Clean quick, ensure the quality of products, the same with the prior art serviceability temperature, can not insulate by the failure line bag, guarantee to obtain request of national standard.
This technology can be saved energy and reduce the cost, and meets current national policy again, and scientific development improves operational environment, reduces air pollution.
Claims (2)
1. the production technology of totally enclosed transformer obturator, be to adopt the unsaturated polyester glass fibre reinforced mould plastic, through heating in die for molding, thereby obtain and prior art requires consistent request of national standard, that is: dielectric strength 2500M Ω, withstand voltage 42KV, it is characterized in that: adopt new material processing, technology is simple, is convenient to general personnel operation, can reduce production costs and material cost, improve competitive power of product.
2. the production technology that replaces the totally enclosed transformer obturator of existing pouring procedure with pressure casting method.Voltage transformer, the current transformer of following (10KV, 6KV, 3KV, 500V) the various models of the 10KV of all use poured with epoxy resin.
