The invention relates to a robot for disassembling and assembling high-temperature connecting pipes, comprising a support mechanism (12) and a base mechanism (13). The support mechanism (12) is arranged on the upper part of the base mechanism (13), and A plurality of movable stations are set, and mechanical claws (14) or mechanical hammers (30) are respectively arranged on the plurality of movable stations, and the plurality of mechanical claws (14) are positioned and grasp each disassembled part of the high-temperature connecting pipe respectively. Assemble and disassemble the parts of the high-temperature connecting pipe through the space movement of the mechanical claw; the mechanical cone (30) includes an arc-shaped guide rail (22) and is arranged on the arc-shaped guide rail (22). The cone head (26), the cone head (26) slides along the arc-shaped guide rail (22) to realize hitting the high-temperature connecting pipe in different radial directions. The application not only automatically knocks and removes the condensed ice slag on the pipeline before disassembling and assembling the connecting pipe, but also can realize the fully mechanized operation of disassembling and assembling the high-temperature pipeline.

The invention relates to a digital protection tester with a fault data model base for protection testing, comprising an ARM (Advanced RISC Machines) processor, a DSP (digital signal processor), 8 inputs and 4 outputs, a FT3 plate, and a GPS (global positioning system) interface, wherein the ARM processor is connected with a host computer through an Ethernet interface, and are respectively connected three optical interfaces (A,B, C) to output data messages to a digital protection device to be tested through the Ethernet; the DSP is connected with the ARM processor through an HPI (hardware platform interface); the 8 input paths and 4 output paths are hung an external parallel I / O bus of the DSP; the FT3 plate is hung on the external parallel I / O bus of the DSP; the FT3 plate on an FPGA (Field Programmable Gate Array) has 12 weak signal output terminals and 3 groups of message output terminals and optical B-code interfaces meeting the standard of IEC60044-8; and the GPS interface is connected with the ARM processor; and the digital protection tester also has an abnormal data restoration and reproduction device. The digital protection tester can determine the effectiveness of the malfunction prevention measures of the digital protection device according to the fault data model base, thereby perfecting the performance of the digital protection device.

The invention belongs to the technical field of automatic control of thermal generator sets, and particularly relates to a checking method for preventing failure of a thermal process protection system of a thermal generator set. The thermal process protection system comprises the following elements: design of the logic of a main protection system of the set, design of an important auxiliary engine protection system of the set, measuring and sampling by an instrument, and allocation of DCS hardware addresses; the inspection method comprises the following steps: collecting the design data of the thermal process protection system, and knowing the composition condition, the operation mode and the operation parameters of the thermal process protection system of the thermal generator set; checking the thermal process protection system of the thermal generator set by referencing to the latest national electric power industry regulations and specifications, and finding design defects and potential safety hazards; proposing a regulating solution for on-site regulation, finishing a static test and a dynamic test, and putting the thermal generator set into safe operation; and if the requirements are not met, returning to the regulation and test steps till meeting the requirement. The checking method has the advantages that the checking steps are simple and clear, the safety and the reliability are realized, the on-site debugging process is simple, and the operation and the implementation are convenient.

The invention discloses a dual-spectrum camera used in alpine regions, belonging to the field of electric power. The camera includes a casing, a hot air system located inside the casing and arranged in the lens, a hot air nozzle arranged on the surface of the lens, and a wiper; the hot air system includes a hot air channel and hot air control device; the hot air control device is located inside the hot air channel; the hot air control device includes a preheating control unit, a fan control unit and a heating control unit; the preheating control unit heats the air at the wide end to obtain preheated air; the fan control The unit pushes preheated air or external air to the tail of the narrow end; the heating control unit reheats the air at the tail of the narrow end; the outer layer of the camera shell and the hot air channel are all made of carbon fiber; The problem that spectral cameras cannot be used in winter in alpine regions can be widely used in substations in alpine regions, eliminating hidden dangers in the operation of substations and reducing the risk of electricity consumption in northern my country.
