Abstract: The present disclosure provides a compressor rotor, a compressor and a refrigerant circulation system. The compressor rotor includes: a motor rotor including a plurality of rotor sections, a locking rod, a compression unit rotating part and a locking member. The rotor sections are fixedly connected in an axial direction and are provided with an axial through hole and the locking rod penetrates through the axial through hole. The compression unit rotating part is located at the end part of the motor rotor and is connected to the locking rod. The locking member is configured to lock the compression unit rotating part on the locking rod. The locking rod, the compression unit rotating part and the locking member form a pressing structure which applies a pressure toward an axial inner side to the motor rotor.

Abstract: A flexible display panel is provided and defined with a special-shaped cutout area and a display area, including a substrate, and a plurality of pixel structures, a scan line layer, and a data line layer disposed above the substrate, wherein each of the plurality of the pixel structures includes three sub-pixels, and the scan line layer includes a plurality of scan lines, and the data line layer includes a plurality of data lines. The sub-pixels are arranged as an array over the substrate, and the scan lines and the data lines are disposed in the array of the sub-pixels. A scan line is disposed between every two rows of the sub-pixels and two data lines are disposed between every column of the sub-pixels in the special-shaped cutout area. Therefore, the frame of the special-shaped cutout area can be reduced to realize the narrow frame of the special-shaped cutout area.

Abstract: The present invention relates to a prevention method of abnormal action protection of UHV regulating compensation transformer with no-load input, the prevention method includes: first determining a value of differential current of regulating compensation transformer, if the value of differential current is smaller than a pre-setting threshold, then, identifying whether an uninterruptible point of differential current waveform meets an pre-setting regulation according to original value of differential current or sampling value of differential difference current, and determining comprehensively whether the regulating compensation transformer is in no-load input or in fault directly with a value of second harmonic content of logic differential current together; if a value of differential current before pre-setting period is larger than the pre-setting threshold, the regulating compensation transformer is diagnosed to have external CT saturation, determining comprehensively whether the regulating compensation tra

Abstract: Sampling implementation method and device based on conventional sampling GOOSE trip mode. CPU of master NPI plug-in, after receiving a second pulse, transmits sampling pulse generation time and a transmission enable bit to FPGA of the master NPI plug-in at a fixed interval; after detecting the transmission enable bit, the FPGA of the master NPI plug-in judges whether time of its internal timer is greater than/equal to the sampling pulse generation time, if yes, generates a sampling pulse to FPGA of collection plug-in; after receiving sampling pulse, the collection plug-in carries out A/D sampling, and transmits sampled data to the master NPI plug-in; when detecting that all A/D samplings are completed, the master NPI plug-in transmits data packets to protection CPU plug-in. The device includes an MMI plug-in, a protection CPU plug-in, a master NPI plug-in and a collection plug-in. Protection maloperation is thereby reduced.

Abstract: A method, system and program product allow an originator of an electronic mail message to create and attach different topics to messages. Recipients of messages can view different topics from an electronic mail message and can take actions on specific topics and related content. Electronic mail messages can be organized based on topics. Each topic in a string of electronic mail messages is chain-scoped with its lifetime bounded by an electronic mail chain.
