Description

Technical Field

[0001] The utility model belongs to the technical field of power equipment protection devices, and in particular relates to a protector for power monitoring equipment. Background Art

[0002] When the power supply or the power parameters of the monitored object exceed the normal operating range, such as a sharp change in voltage or current in the power system, this sharp power change may be caused by power grid failure, equipment aging, external interference or a combination of factors. In this case, the circuit components inside the power monitoring equipment may burn out because they cannot withstand this abnormal power load.

[0003] There may be many reasons for combustion, including but not limited to short circuits, overloads, arc discharges, etc. within the equipment. Short circuits may be caused by aging or damage of the insulating materials inside the equipment, causing the current to form a loop where it should not flow. Overloads are caused by the current exceeding the maximum load capacity of the equipment design. Long-term overload operation causes the equipment to heat up severely, which may eventually cause combustion. Arc discharges are caused by the breakdown of the air between the electrodes under high voltage to form a conductive channel, generating high temperatures and strong light, which are high enough to ignite surrounding materials.

[0004] To prevent this from happening, power systems are usually equipped with circuit breakers as a protective measure. The main function of a circuit breaker is to automatically cut off the circuit when the current exceeds a predetermined value, thereby preventing excessive current from posing a threat to equipment and personal safety. However, circuit breakers sometimes fail to disconnect in time. When there are drastic changes in voltage and current in the power system, if the circuit breaker does not respond quickly enough, the power monitoring equipment may burn before the circuit breaker is activated. In addition, even if the circuit breaker successfully disconnects the circuit, it may not completely prevent the occurrence of combustion. Because once the combustion starts, it may continue to spread due to flammable materials inside the equipment or temperatures that have reached the ignition point.

[0005] In combination with the foregoing, since the power monitoring devices are usually densely arranged, when a power monitoring device of one unit fails, the combustion may spread to the surrounding power monitoring devices. Utility Model Content

[0006] In order to solve the problem of burning after a power monitoring device fails, the utility model provides a protector for the power monitoring device, comprising: a base plate, on which a plurality of power monitoring devices are arranged in an array, each of the power monitoring devices having at least one circuit breaker, and the base plate being provided with a slot body facing the direction in which the power monitoring devices are arranged; wherein a circuit connecting each of the power monitoring devices is hidden in the base plate; and a flame retardant frame, the flame retardant frame being a frame body with an opening on one side, the edge of the opening of the flame retardant frame matching the slot body, the opening surface of the flame retardant frame being fitted onto the base plate and then covering the power monitoring device.

[0007] In some exemplary technical schemes, the power monitoring equipment includes: a monitoring module for monitoring circuit information; a data interface for transmitting the circuit information; wiring terminals, the wiring terminals including at least a first wiring terminal and a second wiring terminal, for externally connecting different circuits; a circuit breaker, the circuit breaker is used to disconnect the circuit connection between the first wiring terminal and the second wiring terminal; wherein the first wiring terminal and the second wiring terminal are both arranged next to the monitoring module; the monitoring module is respectively connected to the first wiring terminal and the second wiring terminal, and the monitoring module is used to monitor the circuit information corresponding to the circuit connected to the first wiring terminal and the second wiring terminal.

[0008] In some exemplary technical solutions, the flame retardant frame has first through holes matching the number of the wiring terminals, and the first through holes correspond to the wiring terminals one by one; wherein each first through hole is directly opposite to the wiring terminal corresponding to itself.

[0009] In some exemplary technical solutions, the base plate is provided with a fault alarm device, and the fault alarm device is coupled to the circuit breaker; wherein the fault alarm device is used to alarm after the circuit breaker is tripped.

[0010] In some exemplary technical solutions, the fault alarm device includes an indicator light and a button arranged on the base plate, and the button is connected to the indicator light.

[0011] In some exemplary technical solutions, the device also includes a lever mechanism, which is arranged next to the circuit breaker, and the lever mechanism includes a lever and a fixed part, and the lever is rotatably fixed on the fixed part; wherein one end of the lever is close to the circuit breaker of the circuit breaker, and the other end faces the button.

[0012] In some exemplary technical schemes, the lever is a bending rod, which includes: a first bending section bent toward one side of the base plate, the end of the first bending section facing the button; a second bending section facing the circuit breaker of the circuit breaker, when the circuit breaker does not disconnect the circuit, the end of the second bending section is in contact with the circuit breaker.

[0013] In some exemplary technical solutions, the flame retardant frame further has a second through hole, the second through hole is located opposite to the lever mechanism, and the lever passes through the second through hole; there is a spacing space between the lower side of the lever and the hole wall of the second through hole.

[0014] The beneficial effect of the utility model is that the flame retardant frame is respectively placed above different power monitoring devices to separate each of the power monitoring devices. When one of the multiple power monitoring devices arranged in parallel fails and causes combustion, the flame retardant frame can block the combustion and prevent the spread of the fire in time. In addition, the lever mechanism is provided, and when a power monitoring device fails, the tripping process of the circuit breaker can drive the lever mechanism to produce a corresponding toggle action to realize the alarm function.

[0029] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] First embodiment: This example discloses a protector for a power monitoring device 2, referring to Figure 1-4 It is understood that it includes: a base plate 1 and a plurality of flame retardant frames 3 covered on the base plate 1. Each of the flame retardant frames 3 is covered with a power monitoring device. Figure 2 As shown, a plurality of the power monitoring devices 2 are arranged in an array on the base plate 1. The power monitoring devices 2 described in this example are actually objects of protection, which may be different in specific situations. For example, a voltage monitor is used to monitor voltage changes in the power grid in real time to ensure the stable operation of the power system. A current transformer is used to measure the current in the power grid and convert high current into measurable low current for easy power monitoring and analysis. A power factor meter is used to measure the power factor in the power grid to evaluate the efficiency and power quality of the power system. The power monitoring devices 2 described can be used alone or in combination to achieve comprehensive monitoring and protection of the power system. In specific applications, appropriate power monitoring devices 2 are selected for configuration according to actual needs, which will not be elaborated here.

[0031] As mentioned above, the power monitoring device described herein should not have any specific limiting effect on the present invention and should be interpreted as being applicable to any type of power monitoring device.

[0032] In a specific example, each of the power monitoring devices has a circuit breaker 201, and the bottom plate 1 is provided with a slot 101 in the direction in which the power monitoring device 2 is arranged. Figure 2 As shown, the tank body 101 is a rectangular tank body 101, and the tank body 101 matches the flame retardant frame 3. It is not difficult to understand that the flame retardant frame 3 forms a protection for the power monitoring device covered by the tank body 101 after matching with the tank body 101. Specifically, when the power monitoring device 2 encounters an abnormal situation during operation, such as flow overload, the circuit components inside the device may generate excessively high temperatures. If this high temperature persists, it may cause the insulating material inside the device to burn, and even cause a fire.

[0033] In this case, since the material of the flame retardant frame 3 has excellent flame retardant properties, once a fire occurs inside a single power monitoring device 2, the flame retardant frame 3 can effectively control the fire within the range of its cover to prevent the fire from spreading to adjacent power monitoring devices 2 or a wider area.

[0034] In the aforementioned example, the base plate 1 contains hidden circuits connecting the various power monitoring devices 2. In this embodiment, the various power monitoring devices 2 are respectively covered in flame retardant frames 3 and arranged in an array on the base plate 1. These power monitoring devices 2 can work independently, and each device is responsible for monitoring different parameters in the power grid to ensure the stable operation of the power system. Therefore, the base plate 1 contains hidden circuits connecting the various power monitoring devices 2. This connection method enables the various power monitoring devices 2 to form a unified monitoring system and work together to provide more comprehensive and accurate power monitoring data.

[0035] In combination with the above content, it can be known that the circuit in the base plate 1 may also cause overheating due to a failure of a single power monitoring device 2, so in a further example, the base plate 1 is a flame retardant material. The aforementioned flame retardant material can be one of various flame retardant materials such as flame retardant polymers, flame retardant glass fiber composite materials, flame retardant metal composite materials, graphite flame retardant materials, mineral flame retardant fillers, etc. This embodiment does not limit the specific material.

[0036] In this example, the flame retardant frame 3 is a frame with an opening on one side, and the opening is actually used to pass the wires.

[0037] Second embodiment: Based on the foregoing embodiment, in this embodiment, the power monitoring device includes: a monitoring module 202, used to monitor circuit information; a data interface 203, used to transmit the circuit information; a terminal 204, including at least a first terminal 2041 and a second terminal 2042, used to connect to different circuits; a circuit breaker 201, used to disconnect the circuit connection between the first terminal 2041 and the second terminal 2042.

[0038] refer to Figure 3 It can be understood that the monitoring module 202 is connected to the circuit breaker 201 for real-time monitoring and analysis of the data of the electrical equipment, which can be realized by a conductor connection plate or other appropriate connection methods to accurately obtain the current and voltage information of the electrical equipment. The data interface 203 is connected to the monitoring module 202 for transmitting the data collected by the monitoring module 202 to an external system or device. The terminal 204 is used to connect the wire or cable to ensure that the current can be smoothly transmitted, and is made of conductive materials such as copper or aluminum to ensure good conductivity. As shown in the figure, the terminal 204 is a screw crimping type, that is, the wire is fixed to the terminal 204 by rotating the screw. In different examples, it may also be a spring clamping type, and the wire is clamped on the terminal 204 by the force of the spring. The monitoring module 202, the data interface 203, and the circuit breaker 201 described in this example are all arranged on the base plate 1.

[0039] In this example, the first terminal 2041 and the second terminal 2042 are both arranged next to the monitoring module 202. As mentioned above, the monitoring module 202 is respectively connected to the first terminal 2041 and the second terminal 2042, and the monitoring module 202 is used to monitor the circuit information corresponding to the circuit connected to the first terminal 2041 and the second terminal 2042. When the current is overloaded, the circuit breaker 201 will be disconnected to prevent failure. However, in some cases, burning may still occur. For example, other components inside the power monitoring equipment (such as capacitors, resistors, etc.) may also fail, resulting in abnormal current in the circuit, which in turn causes burning. In this case, the reaction of the circuit breaker 201 will be delayed to a certain extent. Of course, there are other specific situations, which will not be repeated here.

[0040] Third embodiment: Based on the above embodiment, the flame retardant frame 3 in this example has first through holes 301 matching the number of the wiring terminals 204, and the first through holes 301 correspond to the wiring terminals 204 one by one, wherein each first through hole 301 is directly opposite to the corresponding wiring terminal 204. That is, the first through holes 301 are used to pass different wires.

[0041] In some examples, the base plate 1 is provided with a fault alarm device 102, and the fault alarm device 102 is coupled to the circuit breaker 201. The fault alarm device 102 is used to alarm after the circuit breaker 201 is disconnected.

[0042] Based on the above content, continue to refer to Figure 3In the structure shown, the fault alarm device 102 in this example includes an indicator light 1021 and a button 1022 arranged on the bottom plate 1, and the button 1022 is connected to the indicator light 1021. In some examples, the fault alarm device 102 can also be connected to a communication terminal, and the communication terminal is used to send fault alarm information. The device also includes a lever mechanism 4, which is arranged beside the circuit breaker 201. The lever mechanism 4 includes a lever 401 and a fixing part 402, and the lever 401 is rotatably fixed on the fixing part 402. Among them, one end of the lever 401 is close to the circuit breaker 2011 of the circuit breaker 201, and the other end faces the button 1022.

[0043] When working, under normal working state, one end of the lever 401 is close to the circuit breaker 2011 of the circuit breaker 201 and is in a static state. At this time, the circuit breaker 2011 is in a closed position and the circuit breaker protection is not triggered, while the other end of the lever 401 is in a position away from the button 1022. Once an abnormality occurs in the circuit, such as current overload, the circuit breaker 2011 in the circuit breaker 201 will quickly act to disconnect the circuit to protect the system. The action of this circuit breaker 2011 is the starting point of the linkage of the lever mechanism 4. When the circuit breaker 2011 is disconnected, it will physically push one end of the lever 401. Since the lever 401 is rotatably fixed on the fixed part 402, when one end is pushed, the lever 401 will rotate around the fixed point. As the lever 401 rotates, its other end that was originally away from the button 1022 will gradually approach and eventually press the button 1022 on the bottom plate 1. This button 1022 is connected to the indicator light 1021. Once pressed, a circuit closure will be formed, thereby activating the alarm circuit. After the button 1022 is pressed, the indicator light 1021 lights up, indicating an alarm state. In some advanced configurations, this action also activates the communication terminal, triggering it to send a fault alarm message to a designated receiving system or simply lights up the indicator light 1021.

[0044] Fourth embodiment: Based on the above embodiments, especially the third embodiment, the lever 401 is a bent rod. The specific structure can be referred to Figure 4 It is understood that the bending rod includes a first bending section 4011 bent toward one side of the bottom plate 1, the end of the first bending section 4011 facing the button 1022, and a second bending section 4012 facing the circuit breaker 201 of the circuit breaker 201, and the end of the second bending section 4012 is in contact with the circuit breaker 2011 when the circuit breaker 201 does not disconnect the circuit.

[0045] Specifically, the middle section of the bending rod is rotatably fixed on the fixing portion 402 , and during operation, similar to the process of the third embodiment, an alarm is realized by pressing the button 1022 .

[0046] Fifth embodiment: Based on the above implementation, in one example, refer to Figure 1 It is understood that the flame retardant frame 3 also has a second through hole 302, and the second through hole 302 is located opposite to the lever mechanism 4, and the lever 401 passes through the second through hole 302. There is a spacing space between the lower side of the lever 401 and the hole wall of the second through hole 302. The second through hole 302 is used to pass the lever 401.

[0047] In the process of removing the flame retardant frame 3, first, the flame retardant frame 3 is lifted vertically and smoothly upward. In the process of lifting the flame retardant frame 3, since the lever 401 passes through the second through hole 302, and there is a spacing between the lower side of the lever 401 and the hole wall, the lever 401 will not interfere with the hole wall when the flame retardant frame 3 is lifted vertically. Then, the lever 401 is moved horizontally so that the lever 401 moves relatively into the flame retardant frame 3, and then the flame retardant frame 3 is continuously lifted vertically until it is completely removed from the bottom plate 1. In the whole process, since there is enough spacing between the lever 401 and the hole wall, there will be no jamming.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
