The refrigeration compressor motor starter and the modular structure of the motor run capacitor comprise a box body, a motor starter cavity is arranged at the right end of a box body cavity, and a motor run capacitor box is constituted on the back side of the box body; the compressor motor starter is inserted and embedded in the motor starter cavity; and the capacitor is ran by a compressor motor and installed in a motor run capacitor cavity. . The refrigeration compressor motor starter and the modular structure of the motor run capacitor is characterized by further comprising a compressor electric junction box base and a protection cover, a junction terminal fixing base is constituted on one side of the compressor electric junction box base, a group of junction terminal cavities are constituted on the upper portion of the junction terminal fixing base, compressor electric junction terminals are arranged in each junction terminal cavity, the protection cover and the box body are fixed in an embedded mode, a group of box body locating embedded feet are arranged on the bottom of the box body in an extensible mode, and a circuit locating mechanism and a box body fixing base are constituted on the outer wall of the front side of the box body. The modular effect and the electrical connection effect are good, installation efficiency is high, electrical circuit connection can be standardized, and the connection speed can be improved.

Description

technical field [0001] The invention belongs to the technical field of starting and running devices for refrigeration compressor motors, and in particular relates to a modular structure of a refrigeration compressor motor starter and a motor running capacitor. The motor starter and the motor running capacitor are assembled together to form an integrated modular structure structure. Background technique [0002] As known in the industry, there is a starter in series in the starting circuit of the refrigeration compressor, and the positive temperature coefficient thermistor (PTC) of the starter is in a small resistance conduction state at normal temperature, and when the compressor When the machine is energized and started, the current passes through the PTC and a pair of inserts (also known as contacts) that are in electrical contact with both sides of the PTC to connect the starting circuit of the compressor to start the refrigeration compressor motor. At the same time, at ...

Problems solved by technology

However, the two patents have the following common shortcomings: first, the patents pay attention to their own modular effect, while ignoring the effect of quick positioning and installation with the installation substrate in the refrigerator; second, the function is single, such as the two patents It does not have the function of providing the transfer or relay function of the corresponding line connection for the refrigeration compressor, because the line connecting the compressor includes the power line, the main line of the compressor, the auxiliary line of the compressor and the grounding protection line, etc. The reasonable position of the casing is matched with the terminal block for the power line of the compressor, the main and auxiliary lines of the compressor, and the grounding protection line, and the terminal box is equipped with terminals for these lines to connect, so that not only can the connection line of the compressor be significantly improved. It can also play a corresponding role in electrical safety and improve the wiring efficiency of the compressor.
