The invention discloses a combined type low-voltage switch cabinet. The combined type low-voltage switch cabinet comprises a main body framework, wherein an inner box body is arranged in an inner cavity of the main body framework, and vent holes are formed in the upper end and the lower end of the main body framework; a heat dissipation copper bar plate is connected to the outer surface of the upper end of the inner box body; a fan is connected to the upper portion of the inner cavity of the main body framework, and the fan is located right above the heat dissipation copper bar plate; a soundinsulation plate is further arranged on the inner walls of the two sides of the main body framework, and the sound insulation plate comprises a flat plate and a plurality of obliquely downward inclined plates; the top of the inclined plate is fixed on the surface of the flat plate, and a semi-closed cavity is formed between every two adjacent inclined plates; four supporting legs are symmetricallyconnected to the lower surface of the main body framework, and the tail ends of the supporting legs are pressed against a soft cushion; and the upper surface of the soft cushion is of an arc structure matched with the supporting legs. The switch cabinet has the advantages that the sealing effect and the heat dissipation effect are taken into consideration, the work is stable, and the noise is relatively low.
Description
technical field [0001] The invention relates to a combined low-voltage switch cabinet. Background technique [0002] The low-voltage switchgear is a kind of electrical equipment. The outside line of the switchgear first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is connected according to its needs. In order to ensure the reliability and convenience of small and medium-scale electricity consumption, low-voltage switchgear is used more and more frequently. [0003] The main function of low-voltage switchgear is to switch, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. [0004] The existing combined switchgear is beginning to occupy an increasing m...
