What are the resistance box structure and characteristics?
Resistance box A box type resistor.
It is made up of a number of resistors of different resistance and connected in a certain way. The constant resistance in the resistance box is generally wound with Constantan and Manganese copper wire so that the resistance value does not substantially change with temperature. The laboratory resistance box has plug type and switch type (also called barrel type) two kinds.
The resistance box is an important instrument for electrical measurements in the laboratory. The use of a resistance box improves the accuracy of the readings. When using the resistor box, pay special attention to the current through the resistor can not exceed the allowable value.
Power Power Load Resistor Cabinets Power Chambers, Braking, Load Banks RNW Series (discharge load cabinets, aging resistance boxes), various types of high-power load cabinets, resistance, inductive, non-inductive, capacitive and other Load cabinet, compact structure design, small size, beautiful cabinet shape. It can be continuously operated at rated power, indoor and outdoor type, natural cooling and forced air cooling, low noise and energy-saving fans, load control cabinet with load and control integration, multi-step binning The resistance switches through the switch, reduces the reconnection, the mark is clear and complete, easy to operate.
Features:
· High toughness, which maintains good toughness and is not easy to break under operating conditions where the temperature changes rapidly.
· Thermal design, cabinet structure has the best cooling airflow path, eliminating the local high temperature points and easy to burn.
· The type is complete, according to the size of the flow capacity, there are a variety of resistance components such as strip, corrugated winding, smooth winding and so on.
· Modular resistance elements are modular and can be combined in any combination of strings and parallels to meet the requirements of various parameters such as voltage and resistance and easy to replace.
