Description

Technical Field

[0001] The invention relates to the field of power distribution, and in particular to a meter box switch temperature detection system and a meter box switch. Background Art

[0002] The meter box switch, also known as the meter box inlet and outlet line switch or the meter box switch, is installed in the meter box of the distribution line. It can be divided into many types according to its structure, function and installation method, such as vacuum switch, molded case switch, frame switch, etc. It can cut off or connect the circuit to control the cutting off or connecting of the inlet and outlet circuits, and then realize the transmission and control of electric energy.

[0003] The meter box switch may overheat in many situations, such as:

[0004] When the current in the circuit exceeds the rated current of the meter box switch, it will cause the switch to overheat;

[0005] When a short circuit occurs in the circuit, the current increases sharply, which may easily exceed the load capacity of the switch, causing the switch to heat up rapidly;

[0006] If there is poor contact at the switch connection of the meter box, such as loose screws or loose terminals, the contact resistance will increase, which will cause the switch to generate a lot of heat when powered on.

[0007] After long-term use, the internal structure and materials of the meter box switch will age and wear, resulting in performance degradation and easy overheating during normal use.

[0008] Once the meter box switch overheats, it is more likely to burn out, which may cause power outages and fires, which is not conducive to ensuring electricity safety.

[0009] At present, regular manual inspections and patrols are often used to detect whether the meter box switch is overheated. Although this method is simple and easy to implement, it relies on the experience and responsibility of the inspectors, and there is a possibility of missed inspections and misjudgments. It is also easy for overheating to be discovered in time, resulting in the meter box switch burning out. Summary of the invention

DETAILED DESCRIPTION

[0049] To make the technical solution and advantages of the present invention more clear, the technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0050] The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0052] It should be noted that the present invention uses words such as "first" and "second" to limit the corresponding parts only to facilitate the distinction of the corresponding parts. If not otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0053] The technical solution of the present invention will be introduced and explained below through several embodiments.

[0054] In one embodiment, the present invention provides a meter box switch temperature detection system, the system comprising: a temperature detection device.

[0055] like Figure 1 , Figure 2 As shown, the temperature detection device 100 includes a mounting base 101 and a temperature sensor 102 , a first controller 103 and an over-temperature indicator light 104 arranged on the mounting base 101 .

[0056] The mounting base 101 is used to mount the entire temperature detection device 100 beside or on a housing of a target meter box switch, where the target meter box switch is a meter box switch to be temperature detected.

[0057] The target meter box switch is an electrically controlled switch.

[0058] In this embodiment, the mounting base 101 includes a mounting plate 1011 and a strong adhesive layer 1012 disposed on the back side of the mounting plate 1011 .

[0059] In specific implementation, a protective film can be detachably provided on the surface of the strong adhesive layer 1012. When in use, the protective film can be torn off, and the temperature detection device 100 can be installed next to the switch of the target meter box or on the shell through the strong adhesive layer 1012.

[0060] It can be understood that for a target meter box switch with a housing, the temperature detection device 100 can be installed on the housing of the target meter box switch through the strong adhesive layer 1012. For a target meter box switch without a housing or a housing that is inconvenient to install, the temperature detection device 100 can be installed on the meter box next to the target meter box switch through the strong adhesive layer 1012.

[0061] The first controller 103 is connected to the temperature sensor 102 and is used to detect the temperature of the target meter box switch in real time through the temperature sensor 102 .

[0062] The first controller 103 is also used to determine in real time whether the detected temperature of the target meter box switch reaches a preset temperature threshold.

[0063] The first controller 103 is connected to the over-temperature indicator light 104, and is used to control the over-temperature indicator light 104 to light up when it is determined that the detected temperature reaches a preset temperature threshold, so as to guide maintenance personnel to quickly locate the target meter box switch with over-high temperature.

[0064] The temperature detection device 100 also includes a wiring port 105 for electrically connecting to a target meter box switch. The first controller 103 is connected to the wiring port 105 and is used to control the target meter box switch to disconnect through the wiring port 105 when it is determined that the detected temperature reaches a preset temperature threshold.

[0065] Before use, the entire temperature detection device 100 can be installed next to the target meter box switch or on the housing, and then the control end of the target meter box switch is connected to the wiring port 105.

[0066] When in use, the first controller 103 detects the temperature of the target meter box switch in real time through the temperature sensor 102, and determines in real time whether the detected temperature of the target meter box switch reaches the preset temperature threshold. If it is determined that the detected temperature reaches the preset temperature threshold, the over-temperature indicator light 104 is controlled to light up, and the target meter box switch is controlled to disconnect through the wiring port 105.

[0067] Alternatively, if Figure 3As shown, the system further includes: a data uploading device 200 .

[0068] The temperature detection device 100 further includes a first wireless transmission module 106 .

[0069] The first controller 103 is connected to the first wireless transmission module 106 and is used to transmit the detected temperature of the target meter box switch to the outside in real time.

[0070] The data upload device 200 is used to be installed in a target meter box.

[0071] The target meter box is the meter box where the target meter box switch is located.

[0072] The data upload device 200 includes a second wireless transmission module 201 , a third wireless transmission module 202 , a GPS positioning module 203 and a second controller 204 .

[0073] The second wireless transmission module 201 is used in conjunction with the first wireless transmission module 106 .

[0074] The second controller 204 is connected to the second wireless transmission module 201 , and is used to receive the temperature of the target meter box switch transmitted by the first wireless transmission module 106 through the second wireless transmission module 201 .

[0075] The second controller 204 is connected to the GPS positioning module 203 and is used to collect the location information of the target meter box.

[0076] The second controller 204 is connected to the second wireless transmission module 201 and is used to upload the received temperature of the target meter box switch and the collected location information to the monitoring center in real time.

[0077] When in use, the data upload device 200 can be placed in the target meter box.

[0078] During operation, the second controller 204 receives the temperature of the target meter box switch transmitted by the first wireless transmission module 106 through the second wireless transmission module 201, collects the location information of the target meter box through the GPS positioning module, and uploads the received temperature of the target meter box switch and the collected location information to the monitoring center in real time.

[0079] The monitoring center can be a PC.

[0080] Monitoring personnel can remotely monitor the temperature of the target meter box switch through the monitoring center.

[0081] Optionally, the monitoring center is used to display the temperature of the target meter box switch under the received location information in real time and correspondingly, and is also used to determine in real time whether the temperature of the target meter box switch under the received location information is greater than or equal to the preset temperature threshold. If so, an over-temperature warning of the meter box switch is issued for the target meter box corresponding to the received location information.

[0082] Optionally, the monitoring center is also used to send a meter box switch over-temperature warning message in the corresponding target meter box to a preset maintenance personnel's mobile phone number when issuing a meter box switch over-temperature warning for the target meter box corresponding to the received location information.

[0083] Optionally, a meter box switch over-temperature warning is performed on the target meter box corresponding to the received position information, including:

[0084] It is displayed that the target meter box corresponding to the received position information has a meter box switch over-temperature condition.

[0085] Optionally, the temperature detection device 100 further includes an indicator light off control button 107, such as Figure 4 shown.

[0086] The indicator light off control button 107 is connected to the first controller 103 and is used for the maintenance personnel to send a control signal to the first controller 103 to turn off the over-temperature indicator light 104 .

[0087] The first controller 103 is further configured to control the over-temperature indicator light 104 to turn off after receiving the control signal.

[0088] Maintenance personnel can quickly locate the overheated meter box switch through the over-temperature indicator light 104.

[0089] After the maintenance personnel complete the maintenance of the overheating meter box switch, they can send a control signal to turn off the overtemperature indicator light 104 to the first controller 103 through the indicator light off control button 107. After receiving the control signal, the first controller 103 controls the overtemperature indicator light 104 to turn off.

[0090] Optionally, the number of the temperature detection device 100 is at least one.

[0091] When the number of the temperature detection devices 100 is greater than or equal to two, each temperature detection device 100 is used to be installed one-to-one beside a meter box switch or on a housing in a target meter box where temperature detection is to be performed.

[0092] Optionally, a protective cover 108 is provided on the mounting base 101 of the temperature detection device 100, and the temperature sensor 102, the first controller 103 and the first wireless transmission module 106 are covered in the protective cover 108, and the protective cover 108 is covered with hollow holes 1081. The over-temperature indicator light 104, the indicator light off control button 107 and the wiring port 105 are integrated on the outer wall of the protective cover 108.

[0093] The design and use of the hollow hole 1081 can reduce the weight of the temperature detection device 100 on the one hand, and facilitate air flow on the other hand, thereby helping the temperature sensor 102 in the protective cover to collect a temperature closer to the meter box switch it detects.

[0094] Optionally, the temperature detection device 100 is equipped with a power module, and the power module is used to provide power for the entire temperature detection device.
