Production process of multi-function power transmitter

Abstract

The invention provides a production process for a multifunctional electrical quantity transducer. According to the production process, the technical problems that an existing electrical quantity transducer does not have the corresponding production process and needs to be produced by relying on the experience, and production is complex are solved. The production process for the multifunctional electrical quantity transducer comprises the following steps that a, plates are machined into a shell through a production system, a coating layer is smeared on the shell, and the thickness of the coating layer is 0.4-1.2 mm; b, a fence-type terminal platform is assembled on the outer end face of a face plate; c, a base plate is assembled on the inner end face of the face plate; d, a main board, a transformer and a mutual inductor are assembled in sequence to the base plate; e, an insulating sponge cushion is placed into the shell; f, the face plate is assembled to the shell, and thus a finished product of the multifunctional electrical quantity transducer is obtained; g, the multifunctional electrical quantity transducer is detected through detecting equipment; and h, the multifunctional electrical quantity transducer which is detected to be qualified is packaged and put in storage. The production process has the advantages of fast production.

Description

technical field [0001] The invention relates to a production process of a multifunctional power transmitter. Background technique [0002] A power transmitter is a device that converts measured power parameters (such as current, voltage, power, frequency, etc.) into DC current, DC voltage and isolates and outputs analog or digital signals. [0003] After retrieval, such as Chinese patent literature discloses a power transmitter [application number: 92219217.0; publication number: 2126437]. This kind of power transmitter is composed of an instrument case, an instrument panel with a plug connector, a main board placed on the instrument case, a transformer, a transformer and a connection line, etc., and is characterized in that the host The board is formed by connecting a sample and hold circuit, a central processing circuit and a power supply circuit. [0004] Although the power transmitter disclosed in this patent has high test accuracy, the power transmitter does not have ...

AI Technical Summary

Problems solved by technology

[0004] Although the power transmitter disclosed in this patent has high test accuracy, the power transmitter does not have a corresponding production process and needs to rely on experience for production, which is complicated to produce. Therefore, a production process for a multi-functional power transmitter is designed. is very necessary
