Electrical equipment is a very important product in our electrical work. Distribution cabinet is the main electrical equipment produced and sold by our company. The use has brought convenience to our electrical work, so this product has been widely used. However, the distribution cabinet needs to be cleaned even if it is used for a long time. The power supply must be disconnected before cleaning the distribution cabinet. If it is cleaned when power is on, it is easy to cause leakage and short circuit. Before cleaning the distribution cabinet, check whether the line is open circuit. Then, when cleaning the distribution box, avoid residual moisture in the distribution box. If moisture is found, wipe it with a dry cloth to ensure that the distribution box can only be powered on under dry conditions. Remember not to wash with corrosive chemicals and avoid contact with corrosive liquid or air in the distribution box.

This can save us a lot of time and is very helpful for promotion and rescue. In short, the distribution cabinet is the distribution box, most of which are closed, and the installation method is also vertical installation. Due to different use occasions, the protection of its shell is also different, so we can also select the corresponding products according to the use situation to facilitate our management.

Represented by the letter C. Definition 1: a capacitor, as the name suggests, is a 'container for electricity', which is a device that holds electric charges. Capacitor is one of the electronic components widely used in electronic equipment. It is widely used in circuit isolation, direct intersection, coupling, bypass, filtering, tuning loop, energy conversion, control and so on. Definition 2: capacitor. Any two conductors (including conductors) insulated from each other and closely separated form a capacitor.

Capacitors are different from capacitors. Capacitance is the basic physical quantity, symbol C, unit f (farad). General formula C = q / u special formula for parallel plate capacitor: inter plate electric field intensity E = u / D, capacitor capacitance determination formula C= ε S / 4 π KD with the rapid development of electronic information technology, the upgrading speed of industrial navigation network and digital electronic products is faster and faster. The production and sales of consumer electronic products mainly including flat panel TVs (LCD and PDP), notebook computers and digital cameras continue to grow, driving the growth of capacitor industry.
