DETAILED DESCRIPTION

[0022] The following is a further detailed description of an electric control cabinet with a temperature detection device based on magnetic induction proposed by the utility model in combination with the accompanying drawings and specific embodiments. The advantages and features of the utility model will become clearer according to the following description and claims.

[0023] See also Figures 1 to 3 The utility model provides an electric control cabinet with a temperature detection device based on magneto-electric induction. The back of the electric control cabinet includes a first assembly area 8. A copper bar fixing sleeve 1 is provided in the first assembly area 8. A plurality of vertically arranged copper bars 3 are fixedly provided on the copper bar fixing sleeve 1. The copper bar 3 is used to conduct the current supplied from the power supply equipment in the electric control cabinet to the external equipment. Specifically, the copper bar fixing sleeve 1 is provided with a plurality of copper bar protective sleeves 2. The copper bar protective sleeves 2 are fixedly connected to the copper bar fixing sleeve 1 by bolt components. A plurality of copper bars 3 are sequentially inserted into the plurality of copper bar protective sleeves 2. The copper bar protective sleeves 2 ports are extended from both ends of the copper bar 3. Copper guides are provided at both ends respectively. The copper guides are further electrically connected to the cables in the front and rear circuits. The copper bar protective sleeve 2 is made of insulating material, which is used to prevent the human body from accidentally touching the copper bar 3 and effectively prevent the copper bar 3 from being oxidized, thereby improving the current transmission efficiency.

[0024] A temperature detection device 4 is provided on one end face of the copper bar 3. The temperature detection device 4 is connected to the copper bar 3 through a fixed rubber ring, so that the detection surface of the temperature detection device 4 is attached to the exposed end face of one end of the copper bar 3, which is used to detect the temperature parameters of the copper bar 3. A winding coil made of copper material is provided inside the temperature detection device 4. When current flows through the copper bar 3, according to Ampere's theorem, the copper bar 3 generates a circumferential magnetic field. When the magnetic field and the winding coil generate relative motion, according to Faraday's law of electromagnetic induction, the circumferential magnetic field of the copper bar 3 and the winding coil generate relative cutting motion. The number of turns of the magnetic field lines passing through the coil changes, resulting in a change in the magnetic flux in the coil, and an induced electromotive force is correspondingly generated in the winding coil. The winding coil and the component circuit in the temperature detection device 4 form a loop, that is, a current is generated in the winding coil to power the temperature detection device 4, and the temperature detection device 4 is driven to perform the temperature detection operation of the copper bar 3. It is worth noting that the relative movement between the magnetic field generated by the copper bar 3 and the winding coil can be achieved by moving the relative position of the winding coil and the magnetic field, or by changing the magnetic field strength, and no specific restrictions are made here. By setting the winding coil in the temperature detection device 4, the magnetic field generated by the current flowing in the copper bar 3 is used to generate electricity, so that the temperature detection device 4 no longer needs to be equipped with a battery or powered by an external power supply through a power cord, which greatly simplifies the assembly difficulty of the temperature detection device 4. At the same time, the secondary utilization of energy is achieved. When there is no current flowing in the copper bar 3, its temperature is maintained at room temperature. When there is current flowing in the copper bar 3, the temperature of the copper bar 3 will rise rapidly, and the temperature detection device 4 will also generate power and enter the working state at the same time.

[0025] The back of the electric control cabinet also includes a second assembly area 9, in which a data receiving and transmitting device 5 is provided. The temperature detection device 4 and the data receiving and transmitting device 5 are both provided with matching wireless transmission modules. After obtaining the temperature parameters of the copper bus 3, the temperature detection device 4 transmits the temperature data to the data receiving and transmitting device 5 through the wireless transmission module, and the data receiving and transmitting device 5 further transmits the temperature data to an external mobile receiving terminal. Through the coordinated operation of the temperature detection device 4 and the data receiving and transmitting device 5, the wireless data transmission function within a short distance is realized, and there is no need to arrange data transmission lines, which greatly simplifies the wiring difficulty in the electric control cabinet.

[0026] Through the electric control cabinet with a temperature detection device based on magnetoelectric induction provided by this embodiment, the power on and off and energy supply of the temperature detection device 4 are synchronized with the power on and off of the electric control cabinet, and no human intervention is required. The setting of the temperature detection device 4 and the copper busbar 3 greatly reduces the difficulty of assembling the temperature detection device 4 for the temperature of the copper busbar 3, simplifies the wiring difficulty and subsequent maintenance costs, makes full use of energy for secondary use, and ensures the real-time and stability of temperature detection.

[0027] Preferably, a winding coil protection shell 41 is provided on the outside of the temperature detection device 4 to protect the winding coils and other components and devices inside the temperature detection device 4. A temperature sensing gasket 42 is provided on the bottom end face of the temperature detection device 4. The temperature sensing gasket 42 is attached to the exposed end face of the copper busbar 3. The temperature sensing gasket 42 is based on the thermal effect. When the temperature detection device 4 is powered on, it is used to sense the surface temperature change of the copper busbar 3 and convert the thermal signal into a digital signal and output it to the temperature detection device 4. The temperature detection device 4 can thereby obtain the data on the temperature change of the copper busbar 3.

[0028] Preferably, in addition to the wireless transmission module for realizing the data transmission function with the temperature detection device 4, the data receiving and transmitting device 5 is also provided with a network transmission module. The data receiving and transmitting device 5 is connected to an external mobile receiving terminal or a cloud device. The data receiving and transmitting device 5 can further transmit the temperature data of the copper bus 3 detected by the temperature detection device 4 over a long distance, so that the operator can remotely monitor the real-time changes of the temperature parameters of the copper bus 3, which is convenient for remote monitoring and management of the electric control cabinet. Furthermore, the data receiving and transmitting device 5 can also adopt a power supply method consistent with the temperature detection device 4, that is, when current is generated in the copper bus 3, the data receiving and transmitting device 5 enters the working state, further simplifying the device arrangement and wiring requirements in the electric control cabinet.

[0029] Furthermore, the back of the electric control cabinet also includes a third assembly area 10 and a fourth assembly area 11, wherein the third assembly area 10 is used to install the power supply device, which is connected to the external device through the internal cables and copper busbar 3 of the electric control cabinet, and then supplies power to the external device. The fourth assembly area 11 is provided with a transfer interface, which is used to connect the output end of the copper busbar 3 with the input end of the external device, so as to realize the connectivity between the power supply device and the external device.

[0030] Preferably, a guide rod is provided in the second assembly area 9, and both ends of the guide rod are fixedly connected to the back plate of the electric control cabinet by screws. If the data receiving and transmitting device 5 adopts an external power supply mode, it can be installed on the guide rod. In addition, a fuse 6 and a power switch 7 are also provided in the second assembly area 9, wherein the fuse 6 can be selected as a general fuse or a digital fuse, that is, the fuse 6 and the data receiving and transmitting device 5 are connected to the current flow line inside the electric control cabinet, and the digital fuse and the data receiving and transmitting device 5 can share the temperature data of the copper bar 3 output by the temperature detection device 4. When an abnormality occurs in the electric control cabinet and the temperature parameter of the copper bar 3 exceeds the set threshold, the digital fuse automatically interrupts, so that the current flow line inside the electric control cabinet is disconnected. A general fuse can disconnect the current flow line inside the electric control cabinet when the circuit in the electric control cabinet is overloaded or short-circuited, thereby protecting the internal equipment of the electric control cabinet. The power switch 7 in the second assembly area 9 is used to realize the manual start and stop of the power supply equipment.

[0031] Furthermore, the first assembly area 8 , the second assembly area 9 , the third assembly area 10 and the fourth assembly area 11 are respectively provided with blocking doors at the back of the electric control cabinet to protect the internal devices of the electric control cabinet.
