Method for quickly adjusting heat flux of platinum channel and improving power-supply efficiency

Abstract

The invention provides a method for quickly adjusting the heat flux of a platinum channel and improving power-supply efficiency, which solves the technical problems that: because of incapability of accurately calculating transformer parameters caused by a relatively high loop current in the prior art, more transformer specifications are needed; the designed direct electric heating gear is a little big; and the electric energy utilization rate is a little low. The adopted technical scheme comprises the following steps of: dividing the adaptive transformer in each zone into two types of three-specification structure designs, namely, type A and type B according to the whole design requirements of the platinum channel, outputting adaptive power of each zone by adjusting in a range of between 60 and 90 percent of full load of the transformer according to the design requirements of each zone of the platinum channel, and allowing the full load of the transformer in the range of between 60 and 90 percent to output by means of the matched specification of the adaptive transformer, the combined adjustment technological parameter change of transformation or the electrical heating load ageing. The method of the invention avoids the technical problem that the electrical parameters of platinum load cannot be precisely calculated because of the overhigh loop current, and as the output voltage can be adjusted randomly and precisely, the method solves the problem of low electric energy utilization rate.

Description

technical field [0001] The invention belongs to the field of TFT-LCD glass substrate manufacturing and relates to a design method for a transformer with platinum as a load. The method can effectively improve the effect of electric heating and improve the efficiency of power supply. Background technique [0002] In the production process of TFT-LCD glass substrates, in order to reduce the composition heterogeneity and gas inclusions caused by the contact between glass liquid and refractories, platinum channels are usually used to connect the melting pool and molding equipment. The platinum channel is a device used to realize the clarification, homogenization, stirring and temperature regulation of the glass liquid. Each section of the platinum channel requires its specific function under the corresponding viscosity. Viscosity control is implemented through platinum channel temperature control. [0003] The temperature control of the platinum channel is achieved by electric ...

Problems solved by technology

[0007] The purpose of the present invention is to solve the technical problems in the prior art that the transformer parameters cannot be accurately calculated due to the high loop current, and more transformer specifications are required, and the design of the direct electric heating gear is too large, and the power utilization rate is low. A method to quickly adjust the heat flux of the platinum channel and improve the power supply efficiency is designed. Based on the adaptation structure of the transformer, the selection of the heating mode of the platinum channel and the structure of the channel flange, the transformer is set to two types and three specifications. The direct electric heating transformer is divided into two specifications, and the indirect electric heating transformer is set to the third specification. The tap structure on the primary side or the secondary side of the transformer is used to adjust the output voltage of the transformer through the combination of taps, and then accurately control the platinum load. temperature
