Abstract

The invention provides a system and a method for measuring primary pressure of a contact of a load switch spring system. The system comprises a gram force meter movement device and an image acquisition device, wherein the gram force meter movement device is used for pulling a static stationary spring leaf of a relay to be separated from a dynamic spring leaf through a gram force meter, and used for transmitting an image acquisition instrument when the static stationary spring leaf of a relay is separated from the dynamic spring leaf; the image acquisition device is connected with the ram force meter movement device, and is used for acquiring gram force meter reads according to the image acquisition instruction. By adopting the system and the method, an automatic measurement requirement of the primary pressure of the contact in an ammeter mounting load switch contact spring system can be achieved, measurement on primary pressure of one or more groups of ammeter load switch contacts can be automatically and independently controlled, and thus convenience in quality control and checking of operators can be brought.

Description

technical field [0001] The invention relates to the field of assembly consistency evaluation of a load switch contact spring system for an electric energy meter, in particular to a contact initial pressure measurement system and method for a load switch spring system for an electric energy meter. Background technique [0002] With the popularization of smart energy meters across the country, load switch relays have been widely used as key components for breaking and closing load currents, so as to realize the function of "arrears switching" in the process of grid electricity sales. [0003] The load switch for electric energy meters has the advantages of high conversion depth, large input-output control ratio, and strong anti-interference ability that cannot be replaced by a series of solid electronic devices, and has the advantages of good versatility, high stability, long life, small size and low price. , so it is widely used in various types of smart meters. However, dur...
