[0001] The present invention relates to the technical field of electric power measurement, and in particular to a high-precision electric power measurement meter suitable for complex load environments. Background Art

[0002] Currently, in the field of electric power measurement, traditional current detection methods mainly rely on voltage and current sensors or Hall effect sensors. Although these methods can work effectively under normal conditions, they often cannot provide sufficient sensitivity and stability in complex environments or when high precision is required. For example, voltage and current sensors are easily affected by ambient temperature, which affects measurement accuracy. To improve the accuracy and stability of current measurement, most electric power measurements use multi-sensor redundant monitoring, but in practical applications, this still faces the problem of poor environmental adaptability. The shortcomings of existing technologies include: complex equipment structure, measurement accuracy is significantly affected by environmental factors, and it is difficult to achieve long-term high-precision current monitoring.

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-6 , and further illustrate the technical solution of the present invention through specific implementation methods.

[0021] The present invention provides a high-precision electric power measurement meter suitable for complex load environments, comprising a conductive column 104. Threaded holes are provided at the axial center positions of both ends of the conductive column 104. Welding connection plates 105 are threadedly fixedly installed at both ends of the conductive column 104. The two welding connection plates 105 are fixedly connected to the wires of the required monitoring circuit by soldering; two O-shaped disks 106 are embedded on both sides of the outer surface of the conductive column 104. The O-shaped disks 106 are concentrically arranged with the conductive column 104. The two O-shaped disks 106 are conductively connected via a conductive wire 111. A coil 112 is arranged in series in the conductive wire 111. Two aerogel blocks 117 are overheadly arranged at the axial center of the coil 112. A permanent magnet block 118 is fixedly installed between the two aerogel blocks 117; movable conductive plates 116 are fixedly provided on the opposite back surfaces of the two aerogel blocks 117, and fixed conductive plates 114 are coaxially provided on the sides of the two movable conductive plates 116.

[0022] The two movable conductive plates 116 are electrically connected via a conductive layer 119. The two aerogel blocks 117 and the permanent magnet block 118 are slidably mounted on a ceramic slide 113 at their axial centers, and the ceramic slide 113 is insulated from the conductive layer 119. The ceramic slide 113 is fixed to the rectangular frame 108, and the two fixed conductive plates 114 are fixed to both ends of the ceramic slide 113 and are also fixedly engaged with the rectangular frame 108. A return spring 115 is fixedly mounted between the opposing surfaces of each fixed conductive plate 114 and the movable conductive plate 116. The elastic force of the two return springs 115 needs to be adjusted according to the actual installation angle (by replacing different return springs 115) to ensure that the permanent magnet block 118 is located at the center of the coil 112 and that the elastic force of the two return springs 115 is the same. A return spring 115 is mounted around a ceramic slide 113, with a coil 112 fixedly mounted on a rectangular frame 108. A sealed housing 101 is provided on the outside of the conductive post 104. The two ends of the sealed housing 101 are fixedly sealed to the two ends of the conductive post 104 by sealing side plates 103, so that the sealed housing 101 and the two sealing side plates 103 enclose a sealed space, and this sealed space is vacuum-enclosed. The rectangular frame 108 is fixedly mounted on two parallel reinforced baffles 107, which are sleeved on the conductive post 104 and fixedly engaged with the inner wall of the sealed housing 101. An indicator arrow 102 is provided on the outer surface of the sealed housing 101. An overhead frame 109 is also fixedly mounted on the inner wall of the sealed housing 101. A detection seal cover 110 is fixedly mounted on the overhead frame 109, and the detection seal cover 110 is also fixedly engaged with the two reinforced baffles 107.

[0023] A top cover plate 120 and a bottom cover plate 121 are fixedly mounted on the detection sealing cover 110. The detection sealing cover 110 is fixed between the opposing surfaces of the top cover plate 120 and the bottom cover plate 121. A plurality of magneto-optical glasses 125 and vacuum tubes 126 are arranged in a rectangular array within the magneto-optical glass 125. All magneto-optical glasses 125 and vacuum tubes 126 are arranged in series, cross-connected and terminated by trapezoidal reflectors 124. A light emitter 123 is fixedly mounted on the top cover plate 120, and a light receiving analyzer 122 is fixedly mounted on the bottom cover plate 121. The light emitted by the light emitter 123 coincides with the axis of the first magneto-optical glass 125. The light receiving analyzer 122 is used to receive the light emitted by the light emitter 123. All trapezoidal reflectors 124 are fixed to the opposing surfaces of the top cover plate 120 and the bottom cover plate 121. A barometer is provided within the sealed housing 101 to monitor the pressure within the sealed housing 101.

[0024] When current passes through the conductive column 104, a magnetic field is generated around the conductive column 104, and the magnetic field passes through the axis of the coil 112 (the ratio of the detection sealing cover 110 and the coil 112 to the conductive column 104 in the figure is not the actual size. For the convenience of description, the detection sealing cover 110 and the coil 112 in the figure are magnified). At this time, under the action of the magnetic field, the permanent magnet block 118 will be subjected to magnetic force, thereby driving the aerogel block 117 to move, and the aerogel block 117 will drive the movable conductive plate 116 to move. At this time, the two reset springs 115 will be deformed, and the distance between the fixed conductive plate 114 and the movable conductive plate 116 will change. Therefore, by measuring the distance between the fixed conductive plate 114 and the movable conductive plate 116, the distance between the fixed conductive plate 114 and the movable conductive plate 116 will change. The capacitance value between the conductive plates 116 can be used to determine the displacement of the permanent magnet 118. The displacement of the permanent magnet 118 reflects the deformation of the return spring 115 (the return spring 115 is insulated from the fixed conductive plate 114 and the movable conductive plate 116). The deformation of the return spring 115 is proportional to the magnitude of the force it is subjected to. The force on the return spring 115 comes from the magnetic force exerted on the permanent magnet 118. The magnetic force exerted on the permanent magnet 118 is proportional to the magnetic field strength around the conductive column 104. The magnetic field strength is proportional to the current in the conductive column 104. Therefore, the current inside the conductive column 104 can be monitored by the capacitance value of the fixed conductive plate 114 and the movable conductive plate 116, and the power can be obtained.

[0025] At the same time, O-shaped disks 106 are set at both ends of the conductive column 104. There will be a certain resistance between the two O-shaped disks 106, so there will be a potential difference between the two O-shaped disks 106. At this time, some current will flow through the conductive wire 111, and then the coil 112 will generate magnetic force, which will also push the permanent magnet block 118 to move. Therefore, the permanent magnet block 118 will be affected by the dual effects of the magnetic field around the conductive column 104 and the magnetic field of the coil 112.

[0026] According to the actual situation, the appropriate number of magneto-optical glasses 125 and vacuum tubes 126 are selected. The light emitted by the light emitter 123 enters the first magneto-optical glass 125 through polarization, and then is emitted from the other end of the magneto-optical glass 125 to the trapezoidal reflector 124. The two reflective surfaces of the trapezoidal reflector 124 reflect the light into the next vacuum tube 126, and then it is taken into the next trapezoidal reflector 124 through the vacuum tube 126. This back-and-forth reflection makes the light propagation direction inside all magneto-optical glasses 125 consistent, and the light propagation direction inside all vacuum tubes 126 is consistent. The magneto-optical glass 125 and vacuum tube 126 are all aligned, and the axes of the magneto-optical glass 125 and vacuum tube 126 are parallel (approximately) to the surrounding magnetic field. When the magnetic field around the conductive pillar 104 changes, the current flowing through the conductive pillar 104 changes (the power changes). Because the magnetic field passes through the magneto-optical glass 125, the polarization direction of the light changes (rotating along the axis of the magneto-optical glass 125, or the direction of the magnetic field). This is because the magnetic field acting on the magneto-optical glass 125 rearranges the electrons in the crystal lattice within the magneto-optical glass 125, affecting the propagation of the light. Passing through multiple magneto-optical glasses 125 extends the propagation path of the light, thereby increasing the sensitivity of the measurement. Finally, the light is captured by the light receiving analyzer 122, which detects the polarization angle of the light and uses it to determine the magnitude of the current within the conductive pillar 104.
