Abstract: A method for controlling discharging of a glass plate in a glass plate tempering technology process is provided. After a glass plate is fed into a heating furnace, a monitoring unit monitors and performs filtering on a working parameter of a heating element in real time, and then transmits the filtered working parameter to a control unit. The control unit compares the filtered working parameter with a specified threshold. After the working parameter reaches a maximum value or a minimum value, and then reaches the specified threshold during a subsequent change, the control unit sends an instruction to a drive mechanism. The drive mechanism acts to move the glass plate out of the heating furnace directly or after a time delay, so as to complete a glass plate heating process. The present disclosure changes a conventional time-based control method, reduces energy consumption, and improves quality of a tempered glass.

Abstract: An actuating mechanism control method for a glass plate tempering process, comprising: after a glass plate is conveyed into a heating furnace, a monitoring unit monitors in real time energy consumed by a heating element of the heating furnace, and sends the energy consumed to a control unit to compare with a set threshold; and when the energy consumed by the heating element of the heating furnace is greater than or equal to the set threshold, the control unit sends an instruction to an actuating mechanism to control actions of the actuating mechanism to complete a corresponding tempering process procedure. Through the method that the monitoring unit monitors in real time the energy consumed by the heating element of the heating furnace, a heating procedure of the glass plate is more scientifically and precisely controlled, and, therefore, a discharging moment of the glass plate can be accurately determined.

Abstract: A high-voltage earthing switch is disclosed. A static contact of the earthing switch is connected with the first end of a conductive copper busbar. The second end of the conductive copper busbar is connected with a transformer. The conductive copper busbar includes a first segment and a second segment connected with the first segment. The first segment is one straight segment and an end is taken as an end of the first end of the conductive copper busbar. The first segment extends from the static contact in the direction opposite to the instantaneous action direction of the moving contact when the moving contact engages the static contact. The second segment is connected with the other end of the first segment, and extends towards the side of the first segment facing away from the moving contact.

Abstract: This application discloses a tempering and cooling system for a glass plate. The system comprises a roller table to convey the glass plate, wind gratings to blow air to reduce a surface temperature of the glass plate, and a temperature sensor arranged above and/or below the roller table to detect the surface temperature and enable the system to control a tempering process and/or a cooling process of the glass plate according to the detected surface temperature. The system controls the wind gratings to: produce a first wind pressure when the glass plate is in a tempering stage; produce a second wind pressure when the system determines the detected surface temperature drops to a temperature of a tempering point such that the glass plate enters a cooling stage; produce a third wind pressure when the system determines the detected surface temperature drops to a temperature of a cooling point.

Abstract: The present invention is the field of electrical elements, related to the technology for improving the connection performance of the static contact device for strong current in high voltage switches, especially for a type of static contact device for strong current in high voltage earthing switches. It includes a base, with two Contact Pieces standing face-to-face on it and vertical to its upper end surface. Outside each of the two Contact Pieces, there is a supporting plate, the lower end of which is firmly fixed on the base. Two groups of coaxially stacking Belleville springs are set between each supporting plate and the contact piece on the same side. By way of setting two groups of Belleville springs on one side, the present invention enlarges the contact surface between the Contact Piece and the moving contact blade, effectively reinforcing the gripping for each other.
