Debugging load for direct current power supply switching

Abstract

The invention relates to the technical field of direct current power supply load debugging, and in particular relates to a debugging load for direct current power supply switching. The debugging loadcomprises a protection box. A control panel is bolted with the top of the protection box. A heat dissipation structure is arranged on the left side of the protection box. Moving structures are arranged on two sides of the bottom of the protection box. Sliding grooves are arranged on both sides in the protection box. The inside of each sliding groove is slidably connected with a slide plate. The top of the slide plate is bolted with a load box. Both sides of the bottom of the load box are bolted with first wheels. According to the invention, a hand-moving device is used to smoothly move the load box to facilitate the maintenance of a worker, and then a motor and fan blades are used to effectively dissipate heat of the load box; the service life of the load box is improved; finally, throughadjustable second wheels, the load device can move when needing to move; and the labor intensity of the worker is reduced.

Description

Technical field [0001] The invention relates to the technical field of DC power supply load debugging, in particular to a debugging load used for DC power supply switching. Background technique [0002] The DC power supply has two electrodes, a positive electrode and a negative electrode. The positive electrode has a high potential and the negative electrode has a low potential. When the two electrodes are connected to the circuit, it can maintain a constant potential difference between the two ends of the circuit, thereby forming a positive electrode to the external circuit. The negative current, DC power supply is a kind of energy conversion device, which converts other forms of energy into electrical energy supply circuit to maintain a steady flow of current. The difference between the water level alone cannot maintain a steady flow of water, but with the help of a pump Continuously sending water from a low place to a high place can maintain a certain water level difference an...
