Types of resistors of electric single beam bridge crane


The electric single beam bridge crane resistor is a kind of electrical appliance, which is composed of the resistance element, the replacement equipment and other parts. In the rotor circuit of the asynchronous motor of the winding rotor of the electric single beam bridge crane, its function is to speed and limit the starting and braking current. So what are the models of the electric single beam bridge crane resistors?


What type of electric single beam bridge crane resistors 


The electric single beam bridge crane uses zx2, zx9, ZX10, zx12, ZX15 and other series resistors. Compared with zx9 and ZX10 resistors, zx12 resistor has simple structure, light weight, reliable performance, small parasitic inductance, no self excitation noise and vibration, and easy tapping. In order to match the YZR series motor, a series of R5 resistors, such as RZ5, RK5, RT5 and so on, are also produced.


The alphabet in the resistor model is the meaning of:


T - cam controller, no phase open.


K - cam controller, there is a phase open.


Q - RQR10 type, PQD6402 type lifting control screen;


S - RQS type lifting control panel;


Sf - RQS type lifting control panel;


Y - PQY lift control screen, PQD6401 type translation control screen, no phase open.


L - PQY elevator control screen, there is a phase open.


Z - PQZ type grab control panel;
