Description

Technical Field

[0001] The present application relates to the technical field of passive temperature measurement of power cabinets, and in particular to an octopus-type high-performance transceiver. Background Art

[0002] The power cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the power distribution system. The power cabinet is a general term for the motor control center. The power cabinet is used in occasions with relatively dispersed loads and fewer circuits; the motor control center is used in occasions with concentrated loads and more circuits.

[0003] During use, the power cabinet will be accompanied by a large current, which will generate a lot of heat. When the internal temperature of the power cabinet is high, it will affect the normal use of the entire power cabinet and even the entire power system. Therefore, multi-point temperature monitoring is required inside the power cabinet. The existing technology usually uses wired temperature sensors for temperature measurement, but the wiring of wired temperature sensors is relatively troublesome, especially for the power cabinet. The internal space is limited and there are many lines inside the power cabinet itself, which makes the internal lines of the power cabinet more complicated. If passive temperature measurement technology is used, this problem can be solved, but the existing passive temperature measurement technology usually has only one energy transceiver, which cannot achieve complete synthesis of 90-degree, 180-degree, 270-degree, and 360-degree signals. The energy transceiver performance is low, and the existing energy transceiver is large in size and will occupy a larger internal space of the power cabinet, which has limited internal space.

[0029] See also Figure 1-3 , a preferred embodiment of the present application, an octopus-type high-performance transceiver, comprising: a feeder 1, wherein the feeder 1 is connected to a plurality of energy transceivers 3 via an energy synthesis circuit 2;

[0030] The energy synthesis circuit 2 includes a 50-ohm line 201, one end of which is connected to the feeder 1, and the other end of which is connected to a 1 / 4 wavelength line 202. The 1 / 4 wavelength line 202 is connected to a combiner 1 203, and the combiner 1 203 is connected to an isolator 1 204. The isolator 1 204 is connected to a combiner 2 205 and a combiner 3 206. The combiner 2 205 is connected to an isolator 1 204. The isolator 207 is connected to a 90° phase shifter 208 and a 180° phase shifter 209. The combiner 3 206 is connected to an isolator 3 210. The isolator 3 210 is connected to a 270° phase shifter 211 and a 360° phase shifter 212. The 90° phase shifter 208, the 180° phase shifter 209, the 270° phase shifter 211, and the 360° phase shifter 212 are all connected to an energy transceiver 3.

[0031] The energy transceiver 3 includes a base 301, an L-shaped plate 302 is fixed to the upper end of the base 301, and a plurality of legs 303 are fixed to the end of the L-shaped plate 302 away from the base 301, wherein the height of the legs 303 is 12-13 mm, the long side length of the L-shaped plate 302 is 45-47.4 mm, and the short side length of the L-shaped plate 302 is 23-24.8 mm. The optimal size of the energy transceiver 3 is: the height of the legs 303 is 12.5 mm, the long side length of the L-shaped plate 302 is 46.2 mm, and the short side length of the L-shaped plate 302 is 23.9 mm. This can optimize the energy transceiver's energy transceiver performance and make the transceiver very small, saving space inside the power cabinet after installation.

[0032] In a preferred embodiment, the 1 / 4 wavelength line 202 is connected to two combiners 203, each of which is connected to an isolator 204, each of which is connected to a combiner 205 and a combiner 206, each of which is connected to an isolator 207, each of which is connected to a 90° phase shifter 208 and a 180° phase shifter 209, each of which is connected to an isolator 3 210, each of which is connected to a 270° phase shifter 211 and a 360° phase shifter. Phase shifter 212, the 90° phase shifter 208, the 180° phase shifter 209, the 270° phase shifter 211, and the 360° phase shifter 212 are all connected to the energy transceiver 3.

[0033] like Figure 4 As shown, it is composed of multiple combiners, multiple isolators, and multiple phase shifters. In the schematic diagram below: the 50 ohm line 201 is the signal feeding point, which is transformed by the 1 / 4 wavelength line 202. The impedance of the 1 / 4 wavelength line 202 is 70.7 ohms. Then, it is transformed by the impedance of the 1 / 4 wavelength line 202, synthesized by the combiner 1 203, and isolated by the isolator 1 204 to improve the isolation. One path goes to the combiner 2 205, and then to the isolator 2 207, and then to the 90° phase shifter 208 (i.e., 1 / 4 isolator) to obtain the first 90° signal; after passing through the 180° phase shifter 209 (i.e., 1 / 2 phase shifter), the second 180° signal is obtained. 0° signal. Similarly, the other two signals coming out of the isolator 204 obtain 270° and 360° signals. By setting the energy synthesis circuit 2, the 90°, 180°, 270°, and 360° signals can be completely synthesized, which greatly improves the performance of energy transmission and reception. The transceiver in this application is applied to the temperature measurement of the power cabinet in the power cabinet. It can send energy to the passive temperature sensor and activate the temperature sensor. After the temperature sensor works, the temperature signal is transmitted to the transceiver in a wireless form. After the transceiver receives the energy, it is transmitted back to the lower-level collector, thereby realizing passive temperature measurement of the power cabinet.

[0034] In a further embodiment, the energy transceivers 3 are grouped into groups of four, and the energy transceivers 3 in the same group are respectively connected to the 90° phase shifter 208, the 180° phase shifter 209, the 270° phase shifter 211, and the 360° phase shifter 212. The long sides of the L-shaped plates 302 of the energy transceivers 3 in the same group form a rectangle, and the short sides of the L-shaped plates 302 point inside the rectangle. A gap is reserved between the long sides of adjacent L-shaped plates 302 in the same group, which can further reduce the space occupied by the energy transceivers 3 and further improve the performance of energy transceiver transmission and reception.

[0035] In a preferred embodiment, two legs 303 are fixed to one end of the L-shaped plate 302 away from the base 301. The legs 303 can support the end of the L-shaped plate 302, so that the L-shaped plate 302 is not easily deformed. The base 301, L-shaped plate 302 and bracket are an integrated structure, which can ensure the stability of wireless energy transmission and reception. The base 301, L-shaped plate 302 and bracket are all made of copper material. Copper material not only has good conductivity, but also has low signal attenuation. It is easy to obtain materials and reduce costs while maintaining good conductivity and signal attenuation. Therefore, the use of copper material as the energy transceiver 3 is cost-effective.

[0036] The feeder 1, synthesis circuit and energy transceiver 3 are all installed on a circuit board 4. The circuit board 4 is provided with a plurality of mounting holes 401. The mounting holes 401 can facilitate the installation and fixation of the circuit board 4. The feeder 1 is an RG136 feeder 1. The RG136 feeder 1 is used as a radio frequency connector and adopts a push-in self-locking connection method. It has the advantages of easy installation, small size, light weight and compact structure.

[0037] The transceiver in this application is applied to the temperature measurement of the power cabinet in the power cabinet. It can send energy to the passive temperature sensor to activate the temperature sensor. After the temperature sensor works, the temperature signal is transmitted to the transceiver in a wireless form. After the transceiver receives the energy, it is transmitted back to the lower-level collector, thereby realizing passive temperature measurement of the power cabinet.

[0038] The above are only preferred specific implementations of this application; however, the scope of protection of this application is not limited thereto.
