Description

Technical Field

[0001] The present invention relates to the technical field of function detection of a temperature sensor on an electric energy meter terminal, and in particular to an electric energy meter terminal temperature sensor function detection probe and an electric energy meter terminal temperature sensor function detection device. Background Art

[0002] With the widespread adoption of smart energy meters, ensuring that installation meets requirements and that they operate properly is crucial to the personal and property safety of electricity users and individuals. After a meter has been installed and operated for a period of time, connections can increase in resistance due to issues such as loose screws and metal oxidation, leading to elevated terminal temperatures and, in severe cases, fires. Furthermore, overheating of meter terminals can cause significant line losses. For power grid companies, abnormal line losses represent not only a loss of profitability but also a significant drain on state-owned electricity resources. Therefore, real-time monitoring of terminal temperatures is essential.

[0003] Terminal temperature sensors are currently used to monitor terminal temperatures. Installing these sensors in electricity meters allows for dynamic temperature safety monitoring of critical circuits within the meter. If the temperature exceeds a warning threshold, an event record is generated, providing a basis for mitigation measures and post-accident investigation.

[0004] To ensure accurate and reliable operation of the terminal temperature sensors in electricity meters, functional testing of the sensors is necessary. Currently, the most common heating method is electric heating wires, which can easily overheat, be difficult to cool, and make it difficult to quickly replace the meter under test. Summary of the Invention

[0005] The purpose of the embodiments of the present invention is to provide a probe and device for detecting the function of an electric energy meter terminal temperature sensor. A hot and cold fluid channel for conveying hot and cold fluids is provided inside the probe seat of the probe. When heating is required, hot fluid is passed through the hot and cold fluid channel to heat the electric energy meter terminal; after the detection is completed, cold fluid is passed through the hot and cold fluid channel to quickly cool the electric energy meter terminal.

[0006] To achieve the above objectives, the present invention provides, in a first aspect, a probe for detecting the function of an electric energy meter terminal temperature sensor, which is used to be inserted into a wiring hole of an electric energy meter terminal to perform heat exchange with the electric energy meter terminal and simultaneously collect the temperature of the electric energy meter terminal. The probe comprises:

[0007] A probe seat with hot and cold fluid channels, a probe temperature sensor and a connector are provided inside; the probe seat has a contact end for contacting with the electric energy meter terminal for heat exchange, and the probe temperature sensor is fixed to the contact end of the probe seat through the connector.

[0008] Optionally, the probe further comprises: a thermal insulation pad, the thermal insulation pad being arranged between the connector and the contact end of the probe seat, for isolating the temperature of the probe temperature sensor from the contact end of the probe seat, so that when the probe seat and the electric energy meter terminal perform heat exchange, the probe temperature sensor (106) only collects the temperature of the electric energy meter terminal. The thermal insulation pad can isolate the probe seat from direct temperature contact with the temperature sensor, ensuring that the temperature data measured by the temperature sensor is the temperature data of the electric energy meter terminal.

[0009] Furthermore, the probe base is a three-way probe base, including a first end, a second end, and a third end. The first end is the inlet end for the hot and cold fluids, the second end is the contact end of the probe base, and the third end is the outlet end for the hot and cold fluids. The probe base separates the inlet and outlet ends for the hot and cold fluids, facilitating the control of the hot and cold fluids.

[0010] Optionally, a throttle valve is further provided at the third end of the probe seat, and the throttle valve is used to control the cold and hot fluid outlets to open only when the cold and hot fluids need to be discharged.

[0011] Optionally, the hot and cold fluids include hot and cold liquids. After the hot and cold liquids exchange heat with the probe base, the probe base then exchanges heat with the electric energy meter terminals to achieve temperature regulation of the probe base, with fast temperature regulation speed and high temperature control accuracy.

[0012] Optionally, the hot and cold fluids include hot and cold gases, and the second end of the probe holder further defines an air outlet, through which the hot and cold gases directly exchange heat with the energy meter terminal. A first sealing ring is disposed on the exterior of the second end, capable of sealing the wiring hole after the probe is inserted into the energy meter terminal. The hot and cold gases directly contact the energy meter terminal through the air outlet, accelerating heat exchange with the energy meter terminal. The first sealing ring seals the probe and the energy meter terminal, preventing leakage of the hot and cold gases.

[0013] Optionally, the probe temperature sensor is a wireless temperature sensor. A wireless temperature sensor does not require consideration of data transmission wiring and is flexible to install.

[0014] Optionally, the probe temperature sensor is a wired temperature sensor, and a cable hole is provided at the second end of the probe base. The connecting wire of the probe temperature sensor passes through the cable hole, extends along the hot and cold fluid channels, and extends from the third end of the probe base and connects to the temperature data receiving end. A second sealing ring is provided on the cable hole for sealing the cable hole. The wired temperature sensor requires a connecting wire to be arranged in the hot and cold fluid channels so that a relatively sealed space can be formed for heat exchange between hot and cold gases after the probe is inserted into the terminal of the electricity meter. The second sealing ring tightly wraps the connecting wire and seals the cable hole.

[0015] Optionally, the end portion of the second end of the probe seat is threaded and is threadedly connected to the end portion of the second end via a compression nut; the probe temperature sensor is fixed to the compression nut via a connector. The compression nut can fix the thermal insulation pad to the end portion of the second end.

[0016] Optionally, the connector is an elastic connector. One end of the elastic connector is fixed to the probe temperature sensor, and the other end is fixed to the end of the probe holder. After the probe holder is inserted into the terminal connection hole of the power meter, the elastic connector is compressed. The restoring force of the elastic connector ensures that the probe temperature sensor is always in contact with the power meter terminal, ensuring that the temperature measured by the probe temperature sensor represents the terminal temperature.

[0017] Optionally, the insulation pad is a polytetrafluoroethylene pad. The polytetrafluoroethylene pad is resistant to high temperatures, is electrically insulated, and heat-insulating, and has a certain hardness, can effectively isolate the temperature, and is not easily deformed.

[0018] A second aspect of the present invention provides a device for detecting the function of a temperature sensor at a terminal of an electric energy meter, the device comprising: a control component, a temperature adjustment component, and a communication component;

[0019] The control component is used to:

[0020] Obtain standard temperature data from the temperature regulation component;

[0021] Receive measured temperature data and abnormal alarm data of the measured electric energy meter;

[0022] sending a control instruction to the temperature adjustment component; and

[0023] Performing a temperature sensing function test on the electric energy meter terminal temperature sensor according to the measured temperature data, the abnormal alarm data and the standard temperature data;

[0024] The communication component is in communication with the measured electric energy meter and the control component, and is configured to:

[0025] receiving measured temperature data and abnormal alarm data from the measured electric energy meter; and

[0026] forwarding the measured temperature data and abnormal alarm data to the control component;

[0027] The temperature adjustment component includes the electric energy meter terminal temperature sensor function detection probe, which is connected to the electric energy meter terminal of the electric energy meter being tested and is used to:

[0028] performing temperature adjustment processing on the electric energy meter terminals of the electric energy meter under test according to the control instruction from the control component; and

[0029] The temperature data of the electric energy meter terminal is detected as the standard temperature data. The detection probe used in the detection device can achieve rapid heating and cooling of the terminal of the electric energy meter under test. After the test is completed, the temperature can be quickly cooled to facilitate replacement of the electric energy meter under test. At the same time, the use of fluid for heat exchange can simulate abnormal conditions such as rapid cooling or low temperature, and can realize functional detection of the electric energy meter terminal temperature sensor under low temperature conditions.

[0030] Optionally, the control component includes a control module and a human-computer interaction module;

[0031] The human-computer interaction module is used to receive control instructions input by the operator and transmit them to the control module;

[0032] The control module is used to send the control instruction to the temperature adjustment component; it is also used to obtain standard temperature data from the temperature adjustment component, receive the measured temperature data and abnormal alarm data of the electric energy meter under test, judge the temperature detection accuracy of the electric energy meter terminal temperature sensor based on the measured temperature data and the standard temperature data, and judge whether the abnormal alarm function of the electric energy meter terminal temperature sensor is invalid based on the abnormal alarm data.

[0033] Furthermore, the detection device further includes: a power supply module, which is used to supply power to the electric energy meter under test, the temperature adjustment component, the human-computer interaction module and the control module.

[0034] Optionally, a safety module is provided between the power module and the control module, and the safety module is used to provide safety protection for the control module and prevent anomalies such as overcurrent and overvoltage in the control module.

[0035] Optionally, the detection device further includes: a rack, on which the control component, temperature adjustment component, communication component, power module and safety module are all installed.

[0036] Furthermore, a support is provided on the rack, and the support is used to place the electric energy meter to be measured.

[0037] Furthermore, the detection device further includes: a heat-insulating shielding door, which is mounted on the frame and forms a sealed detection space, wherein the support member is located within the detection space; the electric energy meter under test is placed within the detection space for testing. The heat-insulating shielding door forms a closed, independent, and heat-insulated detection space.

[0038] Through the above technical solution, the present invention provides a power meter terminal temperature sensor function detection probe, which uses hot and cold fluids to adjust the temperature of the power meter terminal, can quickly increase and decrease the temperature, and the temperature control is accurate.

[0039] On the other hand, a device for detecting the function of the terminal temperature sensor of an electric energy meter is provided, which solves the problems of the existing detection such as easy overheating, difficult cooling, and inability to quickly replace the electric energy meter being tested.

[0053] Example 1

[0054] The first embodiment of the present invention provides a power meter terminal temperature sensor function detection probe, which is used to be inserted into the wiring hole of the power meter terminal 200 to perform heat exchange with the power meter terminal 200 and collect the temperature of the power meter terminal 200. Figure 1-2 As shown, the probe 100 includes:

[0055] A probe seat 101, an insulation pad 104, a probe temperature sensor 106 and a connector 105 are provided inside the probe seat 101, which are provided with a hot and cold fluid channel 102; the probe seat 101 has a contact end for contacting with the electric energy meter terminal 200 for heat exchange, and the probe temperature sensor 106 is fixed to the contact end of the probe seat 101 through the connector 105; the insulation pad 104 is provided between the connector 105 and the contact end of the probe seat 101, and is used to temperature isolate the probe temperature sensor 106 from the contact end of the probe seat 101, so that when the probe seat 101 and the electric energy meter terminal 200 are performing heat exchange, the probe temperature sensor 106 only collects the temperature of the electric energy meter terminal 200.

[0056] In this embodiment, the probe base 101 is a three-way probe base, including a first end, a second end, and a third end. The first end is the inlet end for the hot and cold fluids, the second end is the contact end of the probe base 101, and the third end is the outlet end for the hot and cold fluids. The probe base 101 separates the inlet and outlet ends for the hot and cold fluids, facilitating the control of the hot and cold fluids.

[0057] In this embodiment, the hot and cold fluids include hot and cold liquids. After the hot and cold liquids exchange heat with the probe base 101, the probe base 101 then exchanges heat with the electric energy meter terminal 200 to adjust the temperature of the probe base 101 with high temperature adjustment speed and high temperature control accuracy.

[0058] In this embodiment, a throttle valve 111 is further provided at the third end of the probe seat 101. The throttle valve 111 is used to control the cold and hot fluid outlets to open only when the cold and hot fluids need to be discharged.

[0059] In this embodiment, the probe temperature sensor 106 is a wireless temperature sensor 106. The wireless temperature sensor 106 does not need to consider data transmission wiring and is flexible to install.

[0060] In this embodiment, the connector 105 is an elastic connector. One end of the elastic connector is fixed to the probe temperature sensor 106, and the other end is fixed to the end of the probe holder 101. The elastic connector can be a spring. After the probe holder 101 is inserted into the wiring hole of the energy meter terminal 200, the spring compresses. The spring's restoring force ensures that the probe temperature sensor 106 is always in contact with the energy meter terminal 200, ensuring that the temperature measured by the probe temperature sensor 106 represents the terminal temperature.

[0061] In this embodiment, the thermal insulation pad 104 is a polytetrafluoroethylene pad. The polytetrafluoroethylene pad is resistant to high temperatures, is electrically insulated, and heat-insulating, and has a certain hardness, can effectively isolate the temperature, and is not easily deformed.

[0062] During use, the probe 100 needs to be inserted into the wiring hole of the energy meter terminal 200 and fixed with screws. Then, high-temperature liquid is connected through the first end of the probe seat 101. The high-temperature liquid exchanges heat with the energy meter terminal 200 through the side wall of the second end of the probe seat 101 to heat the energy meter terminal 200. The polytetrafluoroethylene pad can isolate the temperature between the probe seat 101 and the probe temperature sensor 106. The probe temperature sensor 106 is always in contact with the energy meter terminal 200 under the elastic force of the spring to collect the temperature of the energy meter terminal 200. After the test is completed, the throttle valve 111 at the third end of the probe seat 101 is opened, and the high-temperature fluid is recovered. At the same time, cold fluid can be connected from the first end to speed up the cooling speed of the energy meter terminal 200, so that the energy meter terminal 200 can be disassembled and the next energy meter terminal 200 can be tested.

[0063] Example 2

[0064] The second embodiment of the present invention provides a power meter terminal temperature sensor function detection probe, which is used to be inserted into the wiring hole of the power meter terminal 200 to perform heat exchange with the power meter terminal 200 and collect the temperature of the power meter terminal 200. Figure 3-4 As shown, the probe 100 includes:

[0065] A probe seat 101, an insulation pad 104, a probe temperature sensor 106 and a connector 105 are provided inside the probe seat 101, which are provided with a hot and cold fluid channel 102; the probe seat 101 has a contact end for contacting with the electric energy meter terminal 200 for heat exchange, and the probe temperature sensor 106 is fixed to the contact end of the probe seat 101 through the connector 105; the insulation pad 104 is provided between the connector 105 and the contact end of the probe seat 101, and is used to temperature isolate the probe temperature sensor 106 from the contact end of the probe seat 101, so that when the probe seat 101 and the electric energy meter terminal 200 are performing heat exchange, the probe temperature sensor 106 only collects the temperature of the electric energy meter terminal 200.

[0066] In this embodiment, the probe base 101 is a three-way probe base, including a first end, a second end, and a third end. The first end is the inlet end for the hot and cold fluids, the second end is the contact end of the probe base 101, and the third end is the outlet end for the hot and cold fluids. The probe base 101 separates the inlet and outlet ends for the hot and cold fluids, facilitating the control of the hot and cold fluids.

[0067] In this embodiment, a throttle valve 111 is further provided at the third end of the probe seat 101. The throttle valve 111 is used to control the cold and hot fluid outlets to open only when the cold and hot fluids need to be discharged.

[0068] In this embodiment, the hot and cold fluids include hot and cold gases. The second end of the probe base 101 is further provided with an air outlet 109, through which the hot and cold gases directly exchange heat with the energy meter terminal 200. A first sealing ring 103 is provided on the exterior of the second end of the probe base 101. This first sealing ring 103 is capable of sealing the connection hole of the energy meter terminal 200 after the probe 100 is inserted into the connection hole. Direct contact between the hot and cold gases and the energy meter terminal 200 through the air outlet 109 accelerates heat exchange with the energy meter terminal 200. The first sealing ring 103 seals the probe 100 and the energy meter terminal 200, preventing leakage of the hot and cold gases.

[0069] In this embodiment, the probe temperature sensor 106 is a wired temperature sensor 106. A cable hole is defined at the second end of the probe base 101. A connecting wire 110 of the probe temperature sensor 106 passes through the cable hole, extends along the probe base 101, and extends from the third end of the hot and cold fluid channel 102 to connect to the temperature data receiving terminal. A second sealing ring 108 is provided on the cable hole to seal the cable hole. The wired temperature sensor 106 requires a connecting wire 110 to be arranged within the internal hot and cold fluid channel 102 so that, after the probe 100 is inserted into the electric energy meter terminal 200, a relatively sealed space is formed for heat exchange between hot and cold gases. The second sealing ring 108 tightly wraps the connecting wire 110 and seals the cable hole.

[0070] In other embodiments, the probe temperature sensor 106 is a wireless temperature sensor that does not require wiring, and no cable hole is required at the second end of the probe base 101. The temperature data receiving end can be a control component of the detection system, a cloud platform, or other temperature data receiving end.

[0071] In this embodiment, the second end of the probe base 101 is threaded and is threadedly connected to the second end via a compression nut 107. The probe temperature sensor 106 is fixed to the compression nut 107 via a connector. The compression nut 107 can fix the thermal insulation pad 104 to the end of the second end.

[0072] In this embodiment, the connector 105 is an elastic connector. One end of the elastic connector is fixed to the probe temperature sensor 106, and the other end is fixed to the end of the probe holder 101. The elastic connector can be a spring. After the probe holder 101 is inserted into the wiring hole of the energy meter terminal 200, the spring compresses. The spring's restoring force ensures that the probe temperature sensor 106 is always in contact with the energy meter terminal 200, ensuring that the temperature measured by the probe temperature sensor 106 represents the terminal temperature.

[0073] In this embodiment, the thermal insulation pad 104 is a polytetrafluoroethylene pad. The polytetrafluoroethylene pad is resistant to high temperatures, is electrically insulated, and heat-insulating, and has a certain hardness, can effectively isolate the temperature, and is not easily deformed.

[0074] During use, the probe 100 needs to be inserted into the wiring hole of the meter terminal 200 and then secured with a screw with sealing tape. The screw with sealing tape and the first sealing ring 103 on the probe base 101 form a sealed space with the meter terminal 200. Hot gas is introduced through the first end of the probe base 101. The hot gas flows out through the air outlet 109 on the second end of the probe base 101, directly exchanging heat with the meter terminal 200, heating the meter terminal 200. A polytetrafluoroethylene pad isolates the temperature between the probe base 101 and the probe temperature sensor 106. The probe temperature sensor 106 is in constant contact with the meter terminal 200 under the elastic force of a spring, collecting the temperature of the meter terminal 200. After the test is completed, the throttle valve 111 at the third end of the probe base 101 is opened to recover the hot fluid. At the same time, cold fluid can be introduced from the first end to accelerate the cooling of the meter terminal 200, allowing the meter terminal 200 to be removed and tested again.

[0087] The temperature data of the energy meter terminal 200 is detected as the standard temperature data. The probe 100 used in the detection device can achieve rapid heating and cooling of the measured energy meter terminal. After the detection is completed, the temperature can be quickly cooled to facilitate replacement of the measured energy meter. At the same time, the use of fluid for heat exchange can simulate abnormal conditions such as rapid cooling or low temperature, and can realize functional testing of the energy meter terminal temperature sensor under low temperature conditions.

[0088] In actual production, the number of detection probes 100 is set according to demand, as each terminal of each electric energy meter needs to be tested. When setting up the detection probes 100, the number of detection probes 100 is determined based on the number of terminals of each electric energy meter and the number of electric energy meters expected to be measured simultaneously.

[0089] In some embodiments, the detection device is capable of measuring 9 tested electric energy meters simultaneously.

[0090] The detection probe 100 uses hot and cold fluids to increase and decrease the temperature of the meter terminal 200 of the energy meter being tested. Therefore, the detection probe 100 also needs to be connected to a storage and recovery device for the hot and cold fluids.

[0091] The electric energy meter under test itself has the function of reporting temperature anomalies. The communication component in this application can directly adopt the same communication protocol as the temperature anomaly data receiving end of the electric energy meter under test to directly establish communication with the electric energy meter under test, saving the cost of building a communication network.

[0092] In actual use, the control component may be an industrial computer or other controller suitable for industrial applications.

[0093] In this embodiment, the control component includes a control module and a human-computer interaction module;

[0094] The human-computer interaction module is used to receive control instructions input by the operator and transmit them to the control module;

[0095] The control module is used to send the control instruction to the temperature adjustment component; it is also used to obtain standard temperature data from the temperature adjustment component, receive the measured temperature data and abnormal alarm data of the electric energy meter under test, judge the temperature detection accuracy of the electric energy meter terminal temperature sensor based on the measured temperature data and the standard temperature data, and judge whether the abnormal alarm function of the electric energy meter terminal temperature sensor is invalid based on the abnormal alarm data.

[0096] In some embodiments, the human-computer interaction module is a display, mouse, keyboard, etc. connected to the control module, and control instructions are input through the mouse or keyboard. In other embodiments, the human-computer interaction module is a touch screen display connected to the control module, and instructions are input through touch. In still other embodiments, the human-computer interaction module is a display, control switch, control knob, etc. connected to the control module, and control instructions are input by adjusting the state of the control switch or control knob.

[0097] In this embodiment, the detection device further includes: a power supply module, which is used to supply power to the tested electric energy meter, the temperature adjustment component, the human-computer interaction module and the control module.

[0098] In some other embodiments, a safety module is further provided between the power module and the control module to provide safety protection for the control module. The safety module is used to prevent the control module from abnormalities such as overcurrent and overvoltage.

[0099] In this embodiment, the detection device further includes: a rack 301 , and the control component, temperature adjustment component, communication component, power module and safety module are all installed on the rack 301 .

[0100] In some other embodiments, a support member 303 is provided on the rack 301 , and the support member 303 is used to place the electric energy meter to be measured.

[0101] In some other embodiments, the detection device further includes: a heat-insulating shielding door 302, which is disposed on the rack 301 and forms a sealed detection space, and the support member 303 is located within the detection space; the electric energy meter under test is placed within the detection space for testing. The heat-insulating shielding door forms a closed, independent, and heat-insulated detection space.

[0102] The detection using the electric energy meter terminal temperature sensor function detection device of the present invention comprises the following steps:

[0103] Step 1: insert the probe into the terminal of the electric energy meter under test, so that the probe temperature sensor at the top of the probe contacts the terminal of the electric energy meter, and the electric energy meter under test establishes communication with the communication component of the detection device;

[0104] Step 2: The operator inputs temperature control instructions to the control module through the human-computer interaction module;

[0105] Step 3: The control module controls the action of the temperature adjustment component, and introduces hot and cold fluids into the probe seat according to the temperature control instructions to heat or cool the terminal of the measured electric energy meter;

[0106] Step 4: The terminal temperature sensor of the electric energy meter under test works and transmits the work-related temperature data and abnormal alarm data to the control module through the communication component; the probe temperature sensor in the probe collects the terminal temperature of the electric energy meter as the standard temperature and transmits it to the control module;

[0107] In step 5, the control module determines the accuracy of the temperature sensor at the terminal of the electric energy meter based on the measured temperature data and the standard temperature data transmitted by the electric energy meter under test, and determines whether the abnormal alarm function of the temperature sensor at the terminal of the electric energy meter is invalid based on the abnormal alarm data. If the accuracy of the temperature sensor at the terminal of the electric energy meter meets the threshold and can normally issue an abnormal information alarm, the temperature sensor function of the corresponding terminal is normal. If the temperature sensors of all terminals of the same electric energy meter under test are normal, the electric energy meter is normal.
