2results about How to "Reduce radiation interference" patented technology

The application provides a motor terminal block assembly, an electric drive system and a hybrid vehicle. The motor terminal block assembly comprises: a terminal block body, wherein an installation portion is formed on the terminal block body; a first wiring assembly, wherein the first wiring assembly is installed on the installation portion and is used for being connected with a high-voltage electrical system; a second wiring assembly, wherein the second wiring assembly is installed on the installation portion and is used for being connected with the high-voltage electrical system; and a third wiring assembly, wherein the third wiring assembly is installed on the installation portion, is located between the first wiring assembly and the second wiring assembly and is used for being connected with a low-voltage electrical system; and wherein filter magnetic rings are respectively sleeved on the first wiring assembly and the second wiring assembly. The motor terminal block assembly integrates high-voltage and low-voltage plug-ins, filters harmonics through the filter magnetic rings, reduces the radiation interference of high-voltage signals on low-voltage signals, and places the low-voltage plug-ins in a shell to avoid the influence of low-voltage radiation current on electromagnetic compatibility level.

This application relates to an irradiation testing system for nuclear power robots. The system includes an irradiation source, at least one irradiation platform, a testing device, and a central control device. The irradiation platform carries the component under test and is positioned close to the irradiation source. The testing device is connected to both the component under test and the central control device via wiring to collect electrical parameters of the component under test during irradiation. The central control device analyzes the radiation resistance of the component under test based on these electrical parameters. A first isolation component is provided between the testing device and the irradiation source. A second isolation component is provided between the central control device and the irradiation source. By collecting the electrical parameters of the component under test in real time during irradiation through the testing device and analyzing them through the central control device, online dynamic monitoring and accurate determination of the radiation resistance of the nuclear power robot are achieved, thereby improving testing accuracy.
