The DC load bank is designed for deep discharge maintenance and capacity detection of battery packs. It is simple to operate and easy to move. It can be applied to various power plants, communication base stations, substations (substations), and battery manufacturers, and is suitable for various models and specifications. Battery. After parameter setting, automatic constant current control completes the capacity test of the battery pack.
Synthetic carbon film and metallic glass glaze film can have very high film resistance, so they are used to make high voltage resistors. In addition to high resistance, high voltage resistors have to withstand a certain amount of power and high voltage. In order to increase the resistance value and obtain a smaller voltage coefficient, the conductive film should be made narrow and long. The length of the synthetic carbon film should not be shorter than 2 cm/kV.
The resistance of the conductor to the current is called the resistance of the conductor. High-voltage resistors are the most used components in all electronic circuits. It is mainly used as a voltage divider and a bleeder resistor in high-voltage devices, with a working voltage of 10-100kV, a slender shape and a large volume, and a power of up to 100W. High-voltage resistors are usually made of glass glaze film and synthetic carbon film.
A shunt resistor is the resistance of a conductor in parallel with a certain circuit. In the case of the total current unchanged, a shunt connected in parallel on a certain circuit will play a role of shunting, and part of the current is passed through the shunt, so that the current passing through the part of the circuit becomes smaller. The smaller the resistance of the shunt resistor, the more obvious the shunt effect.
A shunt resistor is a kind of high precision resistance measurement circuit that uses a very low resistance of an ammeter to measure the current flow in the circuit. It is the resistance of a conductor in parallel with a certain circuit. Because of its particularity, it is generally used in precision electronic products.
Cement resistors are made by winding the resistance wire on a non-alkaline heat-resistant porcelain piece, and adding heat-resistant, moisture-resistant and corrosion-resistant materials to protect and fix the wire. The winding resistor body is placed in a square porcelain frame with special non-combustible heat-resistant It is filled and sealed with cement. The outer side of the cement resistor is mainly made of ceramic material (generally it can be divided into high-alumina porcelain and feldspar porcelain).
