Abstract
A power supply device of fused quartz furnace is equipped with a power transformer, six transformers connected in parallel on the output line of the power transformer, a single-phase resistance furnace having electrode rods connected with the transformers, and a thyristor rectifier serially connected to one of two feed lines of the transformers, wherein the six transformers are divided into three groups, which are respectively connected to arbitrary two phases different from the output line of the power transformer and are configured reasonably to achieve balanced three-phase loads. Accordingly, the power transformer and the transformers can be operated under optimal load condition so as to reduce transformer loss. The thyristor rectifier adjusts secondary current and voltage of the transformers to make them increase slowly in the initial stage and achieve low voltage and large current during production. The power supply device has stable voltage supply, low energy consumption and reduced labor, and the electric power is reduced by 10-15%.
Description
Technical field
The utility model relates to a kind of supply network engineering, and particularly a kind of vitreous silica is produced the electric supply installation of stove.
Background technology
Vitreous silica is the basic material of industries such as high grade refractory, optical fiber, electronics, fine pottery, plastics, with it is raw material, through pulverizing, grinding, moulding, drying, fire the finished product again that forms, coefficient of thermal expansion is little, Heat stability is good, resistance to chemical attack, anti-washing away, viscosity is big during high temperature, the intensity height, heat conductivility is low, and conductivity is low.Because fused quartz product has these good performances, therefore be widely used as engineering material at numerous industrial circles.Present domestic vitreous silica manufacturer adopts the 10KV power supply substantially, a power transformer is joined one to three stokehold transformer, manufacturer is for expanding production capacity, must build many cover production systems, form the high voltage supply shakiness of line loss, many low-power transformers connected in parallel operations, energy loss is big, the production cost height.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed the electric supply installation of the vitreous silica production stove that a kind of voltage supply is stable, loss is little.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of vitreous silica is produced the electric supply installation of stove, be characterized in: it is provided with a power transformer, be parallel with six stokehold transformers on the outlet line of power transformer, the stokehold transformer again with single-phase resistance furnace in electrode bar join, wherein one the tunnel be serially connected with the controllable silicon half-wave rectifying circuit in the two-way inlet wire of stokehold transformer, six stokehold transformers are divided into three groups every group two, three groups of stokehold transformers respectively with inequality any two being connected of power transformer outlet line, thereby guarantee the balance of three-phase load.
The technical problems to be solved in the utility model can also be come by the following technical programs further to realize, on the outlet line of power transformer capacitive compensator is housed.
The utility model adopts a power transformer to join six stokehold transformers, by rational Match, guarantees the balance of three-phase load, and power transformer and stokehold transformer can both be worked under the optimum load state.Transformer loss has reduced relatively; With secondary current, the voltage of controllable silicon half-wave rectifying circuit adjustment stokehold transformer, its satisfied production initial stage electric current, voltage are slowly raise continuously, the requirement of low-voltage, big electric current in the production.Compared with prior art, electric supply installation voltage supply of the present utility model is stable, electric energy loss is little, has reduced operating personnel, but electrical energy saving about 10～15%.
Description of drawings
Accompanying drawing is a structure diagram of the present utility model.
Embodiment
A kind of vitreous silica is produced the electric supply installation of stove, and electric power system primary voltage grade is 35KV.35KV power supply grid voltage is more stable relatively, and line loss is little, and power outage is few, the power supply quality height.Under the prerequisite of the balance that guarantees three-phase load, a power transformer 1 is joined six stokehold transformers 4, and capacitive compensator 2 is housed on the outlet line of power transformer 1.Stokehold transformer 4 again with single-phase resistance furnace in electrode bar 5 join, wherein one the tunnel be serially connected with controllable silicon half-wave rectifying circuit 3 in the two-way inlet wire of stokehold transformer 4, six stokehold transformers are divided into three groups every group two, three groups of stokehold transformers respectively with inequality any two being connected of power transformer outlet line.Triple line as power transformer 1 outlet line is respectively A, B, C, and three groups of connected modes of stokehold transformer are: one group joins with A, B line, and one group joins with A, C line, and one group joins with B, C line, thereby guarantees the balance of three-phase load.
