DESIGN OF PLANAR RESISTOR HOUSING Russian patent published in 2019 - IPC H01C1/02 H01C1/22 H01C1/14 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, namely to the design of the planar resistor casing, in which the electrodes of the said planar resistor (4) are on one side of the resistor, and main part (1) of above mentioned casing design is insulating material covering resistor surface, at that around wiring (4) of resistor electrodes is insulating structure (3) with a hole facing resistor side or outer side, said insulating structure (3) has toothed or slotted structure. Compared with the existing equipment, the slot structure provides a long path of current leakage on the surface of the insulating material between two poles, in accordance with the orientation of the installation of the electrodes, the slot hole can be turned inward or outward, and such design makes it difficult to get dust and dirt inside, increases reliability of resistor and eliminates need for maintenance.

EFFECT: preventing the phenomenon of electrification and high reliability of protecting the planar resistor.
