摘要： A housing structure of a planar resistor is provided, wherein electrode extraction ends (4) of the planar resistor are on the same side of the resistor. A housing structure body (1) is made of an insulating material covering the surface of the resistor. An insulating structure (3) having a groove opening facing toward or away from the resistor is provided around each electrode extraction end (4) of the resistor. The insulating structure (3) is configured to be a multi-tooth or multi-groove insulating structure. Compared with the prior art, a structure having teeth or slots increases the surface creepage distance of an insulating material between two electrodes. Since the electrodes are mounted toward different directions, and a multi-groove opening is designed to face inward or outward, dust and dirt can hardly enter the resistor, so that the operating reliability and maintenance-free property of the resistor are improved.

摘要： A thyristor assembly radiator for a DC converter valve. A water discharging port of an N th radiator is communicated with a water discharging port of an (N-2) th radiator. A water feeding port of the N th radiator is communicated with a water feeding port of an (N+2) th radiator. Or, a water feeding port of the N th radiator is communicated with a water feeding port of the (N-2) th radiator, and a water discharging port of the N th radiator is communicated with a water discharging port of the (N+2) th radiator. A water discharging port of an M th radiator is communicated with a water discharging port of an (M-2) th radiator, and a water feeding port of the M th radiator is communicated with a water feeding port of an (M+2) th radiator, or a water feeding port of an M th radiator is communicated with a water feeding port of the (M-2) th radiator, and a water discharging port of the M th radiator is communicated with a water discharging port of an (M+2) th radiator. Water feeding ports of the last two radiators are communicated. According to the radiator, the number of joints of a cooling system is reduced, the risk of leakage is lowered, the operation reliability of a converter valve is improved, the maintenance difficulty is lowered, and the maintenance time is shortened.
