Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric pressure plate technology, specifically an electric pressure plate. Background Technology
[0002] Electrical control switches, also known as power circuit breakers, are physical devices used to connect or disconnect certain circuits in the secondary circuits of a power system. They often exist in the form of plug-ins or switches. These devices are mainly used in protection, control, and measurement circuits. By enabling or disabling the control switches, specific functions can be activated or deactivated, thereby ensuring the safe and stable operation of the power system. For example, in substations, workers can operate control switches to activate and deactivate protection devices for maintenance or to handle different operating conditions. Therefore, electrical control switches are an indispensable part of the power system and play a crucial role in the system's reliability and safety.
[0003] In existing technologies, power pressure plates are usually fixed to the conductor plate with a fixing cap to prevent misoperation. Although this meets the usage requirements to a certain extent, it has been found in actual use that when a circuit breaking operation is required, the operator needs to first rotate the fixing cap to release the conductor plate, and then rotate the conductor plate to complete the operation. This operation takes a long time and may delay the response speed in emergency power outages or fault handling. Utility Model Content

[0011] Preferably, a humidity sensor is fixedly installed on one side of the current sensor.
[0012] Compared with the prior art, the beneficial effects of this utility model are: the electric pressure plate; 1. By replacing the existing method of fixing the conductor plate with an adjustment mechanism, spring and two sets of extrusion plates, the circuit breaking operation can be completed by simply rotating the conductor plate. This changes the traditional method of rotating to release the fixing cap constraint to directly overcoming the spring pressure, greatly simplifying the operation process and solving the problem of long operation time and potential delay in response speed during emergency power outages or fault handling in the existing technology. 2. By creating a label slot on the top of the toggle block, labels can be easily placed, allowing workers to quickly and accurately mark and identify the function or status of each pressure plate, greatly improving work efficiency and reducing the risk of misoperation. Furthermore, the protective cover of the rotating connection has a transparent window, which not only provides physical protection for the labels, preventing damage or fading due to environmental factors, but also allows workers to clearly view the label information without opening the protective cover. This design ensures that the labels maintain good visibility even after long-term use. 1. A detection mechanism integrating multiple sensors and intelligent monitoring functions monitors the current flowing through the conductive plates in real time, effectively detecting overcurrent, short circuits, or abnormal conduction. Simultaneously, temperature sensors prevent poor contact or fire risks caused by overheating, while humidity sensors help monitor ambient humidity, preventing insulation degradation or condensation. Through the connection port, all monitoring data can be transmitted to an external control terminal for analysis and processing, enabling maintenance personnel to take timely measures to address potential problems and ensure the safe and stable operation of the power system.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0018] Example 1 Please see Figure 1-3 This utility model provides a technical solution: an electric pressure plate, including a main body 1, a toggle mechanism 2 fixedly installed inside the main body 1, a detection mechanism 3 fixedly installed inside the main body 1, the main body 1 including a mounting shell 101, a negative electrode contact portion 102 fixedly installed inside the mounting shell 101, a positive electrode contact portion 103 fixedly installed inside the mounting shell 101, and a conductive piece 104 rotatably installed on the outer wall of the positive electrode contact portion 103, the circuit of this device is controlled by rotating the conductive piece 104. The negative electrode contact 102 is slidably connected to two sets of extrusion plates 105. The two sets of extrusion plates 105 are respectively disposed on the upper and lower sides of the conductive plate 104. Each set of extrusion plates 105 has a guide groove 106 on the side closest to the conductive plate 104, facilitating the insertion of the conductive plate 104 between the two sets of extrusion plates 105. A spring 107 is slidably connected to the outer wall of the negative electrode contact 102, and the spring 107 is disposed on the top of the extrusion plates 105. A [missing information - likely a device or component] is fixedly disposed on the top of the negative electrode contact 102. An adjusting mechanism 108 is disposed on top of the spring 107. The adjusting mechanism 108 includes a screw 1081, an adjusting cap 1083 threadedly connected to the top of the screw 1081, an adjusting plate 1082 slidably connected to the outer wall of the screw 1081, a plurality of limiting grooves 1084 formed on the outer wall of the screw 1081, and a plurality of limiting protrusions 1085 formed on the inner wall of the adjusting plate 1082. The limiting protrusions 1085 are slidably connected within the limiting grooves 1084, and the adjusting mechanism 1082 is adjusted by means of the limiting grooves 1084 and the limiting protrusions 1085. The adjustment plate 1082 is restricted to move in the direction of displacement on the outer wall of the screw 1081 by the cooperation between the adjustment cap 1083 and the screw 1081, so that the adjustment plate 1082 can only move up and down on the outer wall of the screw 1081 and cannot rotate. Then, by the cooperation between the adjustment cap 1083 and the screw 1081, when the operator rotates the adjustment cap 1083, the adjustment plate 1082 can be moved up and down on the outer wall of the screw 1081. In turn, the tension of the limiting groove 1084 is changed by the adjustment plate 1082, thereby changing the squeezing force between the two sets of extrusion plates 105 and the conduction plate 104.
[0019] This utility model's power pressure plate replaces the existing method of fixing the conductive piece 104 with an adjusting mechanism 108, a spring 107, and two sets of pressing plates 105. During circuit breaking operations, only the conductive piece 104 needs to be rotated to complete the operation, solving the problems of long operation time and potential delays in response speed during emergency power outages or fault handling in the prior art. Specifically, the spring 107 presses the conductive piece 104 between the two sets of pressing plates 105. This solves the problem of abnormal displacement of the conductive piece 104. Due to the characteristics of the spring 107, when the conductive piece 104 enters or leaves between the two sets of pressing plates 105, it only needs to overcome the elastic force of the spring 107. This transforms the traditional method of rotating to release the fixing cap constraint into directly overcoming the pressure of the spring 107, significantly simplifying the operation process.
[0020] Example 2 Please see Figure 1-4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the toggle mechanism 2 includes a fixing frame 201, which is fixedly mounted on the top of the conductive piece 104. A toggle block 202 is fixedly mounted on the top of the fixing frame 201. The toggle mechanism 2 is fixedly mounted on the top of the conductive piece 104 by the fixing frame 201. A label groove 203 is opened on the top of the toggle block 202. A label is placed in the label groove 203 to facilitate personnel marking and identification of this device. A protective cover 204 is rotatably connected to the top of the toggle block 202. A transparent window 205 is fixedly mounted inside the protective cover 204 to protect the label. The transparent window 205 facilitates personnel to observe the label. A baffle plate 206 is fixedly installed on one side of the fixing frame 201. The baffle plate 206 is located on the side of the conductive piece 104 away from the groove. The baffle plate 206 prevents the conductive piece 104 from contacting the conductive plate on the adjacent pressure plate structure when rotating.
[0021] Example 3 Please see Figure 1-5As another preferred embodiment of this utility model, the difference from embodiment 1 is that the detection mechanism 3 includes a main control box 301. A current sensor 302 is fixedly installed on the top of the main control box 301, and an elastic contact 303 is fixedly installed on the top of the current sensor 302. A connection port 304 is provided on one side of the main control box 301. The main control box 301 is connected to an external control terminal for data transmission through the connection port 304. A temperature sensor 305 and a humidity sensor 306 are fixedly installed on one side of the current sensor 302. The elastic contact 303 ensures the electrical connection between the current sensor 302 and the conductive piece 104. The current sensor 302 monitors the current flowing through the conductive piece 104 in real time to determine whether there is overcurrent, short circuit or abnormal conduction. The temperature sensor 305 detects the temperature of the conductive piece 104 to prevent poor contact or fire caused by overheating. The humidity of the environment where the pressure plate of the connection port 304 is located is monitored to prevent the insulation performance from deteriorating or condensation.
