Problems solved by technology

The disadvantage of this type of method is that the soldering chamber is subjected to the entire temperature and pressure range under ambient conditions, i.e. from room temperature and atmospheric pressure to high vacuum and soldering temperatures
This results in a longer time from loading the solder chamber with atmospheric pressure during loading to pumping to high vacuum
Cooling of the soldering process chamber to ambient temperature at each charge change (Chargenwechsel) leads to longer reheating times required to reheat the process chamber to the soldering temperature

Embodiment Construction

[0047] A processing method for a vacuum switch assembly, comprising the following steps: a. placing a pre-assembled vacuum switch tube in a pretreatment chamber arranged in front of the welding treatment chamber, and performing preheating and pre-evacuation; b. Transferring the pretreated vacuum interrupter tube into the welding treatment chamber and placing it at the welding temperature under high vacuum; c, transferring the welded and evacuated vacuum interrupter tube to the cooling treatment chamber for cooling; d, placing The cooled vacuum switch tubes are continuously delivered to the ventilation chamber 1 for ventilation; here, the delivery and transmission of the vacuum switch tubes are carried out under vacuum conditions.

[0048] At least one pre-assembled vacuum interrupter or assembly is first placed in the loading process chamber of said pre-processing chamber and heated to a temperature above ambient temperature under low vacuum; then transported to pre-processing ...

Abstract

The invention discloses a processing method for a vacuum switch assembly. Empty; b, transfer the pretreated vacuum interrupter to the welding process chamber and place it at the welding temperature under high vacuum; c, transfer the welded and evacuated vacuum interrupter to the cooling process chamber for cooling ; d. Continue to convey the cooled vacuum switching tube to the ventilation chamber for ventilation.

Description

technical field [0001] The invention belongs to the technical field of vacuum switches, and in particular relates to a processing method of a vacuum switch assembly. Background technique [0002] The vacuum switch is a switch that detects the range of vacuum, also known as vacuum relay. Its function is: when the vacuum degree generated in actual work reaches the specified requirements, the control circuit will be automatically opened and closed, and an electrical signal will be sent to instruct the vacuum adsorption mechanism to operate normally. It belongs to reliability and safety components. [0003] A prior art method for manufacturing vacuum interrupters that transfers preassembled vacuum interrupters to a welding process chamber that is evacuated to a high vacuum, where the preassembled vacuum interrupters are assembled with all Parts but not yet final assembled, i.e. vacuum-tight welded vacuum interrupters. After reaching a high vacuum, the soldering chamber is hea...
