Embodiment Construction
[0029] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the protection scope of the present invention.
[0030] Such as figure 1 As shown, the present invention provides a modular electric control cabinet (also referred to as a modular electric control cabinet), which includes at least three modular units with different functions, and the at least three modular units with different functions include at least one A start-up unit with incoming lines, at least one intermediate start-up unit without incoming lines, and at least one control unit, and adjacent units are connected to each other. Through the above structural design, the modular electric control cabinet can be used to control multiple different controlled objects, especially the electric control cabinets f...

The present invention provides a modular electric control cabinet, which includes at least three modular units with different functions. The at least three modular units with different functions include at least one starting unit with incoming lines, at least one intermediate unit without incoming lines A starting unit and at least one control unit are connected to each other between adjacent units. According to the modular electric control cabinet of the present invention, it can control multiple different controlled objects, especially the electric control cabinets for different parallel units can be formed by assembling each modular unit in the modular electric control cabinet , avoiding the design of an electric control cabinet every time a parallel unit is developed, effectively enhancing its versatility; also avoiding the formation of a larger-sized overall electric control cabinet, avoiding welding deformation caused by large-area welding, thus affecting the entire The appearance of the electric control cabinet; it can also effectively realize the wiring connection between the electric control module unit cabinets. The invention also relates to a compressor unit control system including the electric control cabinet.
Description
technical field [0001] The invention belongs to the field of refrigeration equipment, and in particular relates to a modular electric control cabinet and a compressor unit control system including the electric control cabinet. Background technique [0002] At present, in the design of the existing integrated electric control cabinet, the size of the electric control cabinet is different according to the number of compressors connected in parallel in parallel units. The whole series has 1 to 6 compressors connected in parallel, and the electric control cabinet needs to design 6 electric control cabinets of different sizes. The generality of the cabinet is not strong; and in terms of technology, the entire cabinet is designed as a one-piece large cabinet. If the size design of the overall electric control cabinet is too large, the diagonal deviation of the electric control box will be too large due to the existence of welding deformation, and multi-item There are large steps t...
