The invention relates to a suspended guide-rail-type high-altitude operation platform and a manufacturing method. The operation platform comprises a U-shaped platform as a construction support, a horizontal support beam capable of enabling the U-shaped platform to be supported at the top of a corridor and a walking device capable of enabling the operation platform to be moved along the corridor. The U-shaped platform comprises a bottom cross beam positioned below the corridor, and vertical arm frames which are vertically installed at two ends of the bottom cross beam and positioned at the sidepart of the corridor. Two ends of a horizontal support beam are connected with the upper ends of the two vertical arm frames. The walking device comprises a rail installed at the top or side upper part of the corridor, a rail wheel installed at the bottom of the horizontal support beam and a driving mechanism for driving the horizontal support beam. The suspended guide-rail-type high-altitude operation platform is capable of, through connection of the U-shaped platform and the horizontal support beam, enabling a whole structure of the operation platform to be in a state that the left, right and lower three faces of the corridor to be constructed are surrounded, using the operation platform as the support, safely and conveniently constructing the bottom and the side face of the corridor, and solving problems in the prior art, and has active technological significance.

The invention discloses a zero-sequence current detection system for a 10KV transmission line. There is a zero-measuring transformer between the point and the signal common terminal com. The first end of the side coil is connected with a zero-sequence current sampling resistor Rx, one end of the resistor Rx is connected to the integrated signal processing circuit, the other end of the resistor Rx is connected to the com terminal, and the tail end of the secondary coil of the zero-measuring transformer is connected to the com terminal. The invention changes the mode of detecting the zero-sequence current of the 10KV transmission line in the prior art, realizes miniaturization and stealth, greatly improves the detection accuracy, and completely eliminates the problem of false detection of false "zero-sequence current".

The invention discloses a focusing type cold cathode X-ray tube which comprises a field emission cold cathode, a lamp filament gate electrode formed by lamp filaments, an anode, an X-ray tube case and a ray emergence window, wherein the field emission cold cathode and the anode are respectively arranged at two ends inside the X-ray tube case and are respectively extracted to the outside of the X-ray tube case through a cathode extraction electrode and an anode extraction electrode; the lamp filament gate electrode is arranged between the field emission cold cathode and the anode; two side surfaces of the lamp filament gate electrode are extracted to the outside of the X-ray tube case through the two extraction electrodes; the anode is provided with a slope surface for generating an X-ray by electron bombardment; and the ray emergence window is arranged at the position on the side surface of the e X-ray tube case, which is just opposite to the slope surface. Compared with the general field emission cold cathode X-ray tube, the focusing type cold cathode X-ray tube can be used for effectively carrying out electron bombardment on the anode to degass, improving the vacuum degree in the X-ray tube, simultaneously focusing electron beams, improving the performance of the X-ray tube and prolonging the service life of the X-ray tube.
