[0030] In order to enable people in the technical field to better understand the present solution, the technical solution in the embodiment of the present solution will be clearly described below in conjunction with the drawings in the embodiment of the present solution. Obviously, the described embodiment is an embodiment of a part of the present solution, not all of the embodiments. Based on the embodiments in the present solution, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present solution.

[0031] The term "including" and any other variations in the specification and claims of this solution and the above drawings mean "including but not limited to", and is intended to cover non-exclusive inclusions and is not limited to the examples listed in the text. In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0032] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:

[0033] Figure 1 This is a schematic diagram of the external structure of a high-voltage electroscope provided in an embodiment of the present disclosure. Figure 1The high-voltage electroscope comprises an electroscope housing 10, a connection electrode 11, an alarm module 12, an integrated circuit board 13 and an insulating rod 14;

[0034] The connecting electrode 11 is arranged on the upper side of the electroscope housing 10, the insulating rod 14 and the alarm module 12 are arranged on the lower side of the electroscope housing 10, and the alarm module 12 and the insulating rod 14 are distributed on the left and right sides;

[0035] The integrated circuit board 13 is arranged inside the electroscope housing 10 and is connected to the alarm module 12 and the electrodes respectively. The integrated circuit board 13 and the alarm module 12 are vertically arranged up and down.

[0036] In this embodiment, the high-voltage electroscope includes an electroscope housing 10, a connecting electrode 11, an alarm module 12, an integrated circuit board 13 and an insulating rod 14. The working principle of the high-voltage electroscope is as follows: the connecting electrode 11 is connected to the object to be detected, and the charge on the object to be detected is transferred to the integrated circuit board 13. The integrated circuit board 13 detects the amount of charge carried by the object to be detected and determines the voltage value. When the voltage value exceeds 10% of the rated voltage value, the integrated circuit board 13 sends abnormal information to the alarm module 12, and the alarm module 12 sends a warning message to remind the operator to pay attention to safety.

[0037] Specifically, the contact electrode 11 is disposed on the upper side of the electroscope housing 10 and is used to contact the detected object to transfer electric charge. The contact electrode 11 is usually made of a conductive material, such as metal.

[0038] The insulating rod 14 and the alarm module 12 are both arranged on the lower side of the electroscope housing 10, and the alarm module 12 and the insulating rod 14 are distributed on the left and right sides. The insulating rod 14 is used to support and operate the electroscope, so that it keeps a certain distance from the detected object to ensure the safety of the operator. Considering the problem that the alarm module 12 is falsely triggered due to the external force on the insulating rod 14, the embodiment of the present disclosure can reduce the occurrence of the situation where the alarm module 12 is falsely triggered due to the external force on the insulating rod 14 by changing the position distribution of the alarm module 12 and the insulating rod 14.

[0039] When the insulating rod 14 is subjected to external force, the insulating performance of the insulating rod 14 may be reduced, thereby affecting the detection accuracy of the electroscope; in severe cases, the reduced insulation performance may lead to leakage or electric shock accidents. If the external force is too large, the insulating rod 14 may be deformed or broken, affecting the normal use of the electroscope; in severe cases, the breakage of the insulating rod 14 may cause the electroscope to directly contact the object being detected, thereby causing a safety accident.

[0040] The alarm device is arranged at the lower side of the electroscope housing 10, and is used to send out an alarm signal, such as a sound signal or a light signal, when detecting that an object is charged, so as to remind the operator to pay attention to safety.

[0041] The integrated circuit board 13 is arranged inside the electroscope housing 10, and is connected to the alarm module 12 and the contact electrode 11 respectively. The integrated circuit board 13 and the alarm module 12 are vertically distributed up and down. The integrated circuit board 13 can receive the charge transmitted by the contact electrode 11. After the internal sensing element detects the electrical signal, it amplifies, filters and processes the weak electrical signal and converts it into a signal form that is easy to process. When the sensing element detects that the object is charged, the integrated circuit board 13 will control the amplifier circuit to amplify the electrical signal and drive the alarm module 12 to issue an early warning. The integrated circuit board 13 can convert the external power supply into a voltage and current suitable for the operation of the internal circuit, and provide protection when the power supply is abnormal, ensuring the normal operation of the electroscope.

[0042] In the prior art, reference Figure 6 The buzzer is arranged inside the electroscope housing, and the buzzer and the insulating rod are vertically arranged up and down, that is, the buzzer is at the top of the insulating rod. The circuit board is connected to the buzzer and is vertically arranged up and down, that is, the circuit board is on the upper side of the buzzer. When the insulating rod is subjected to external force, it may touch the buzzer, or even disconnect the solder joint connecting the buzzer and the circuit board, causing damage to the electroscope and affecting the normal detection of the operator.

[0043] The high-voltage tester provided in this embodiment can detect whether the AC high-voltage live equipment is live. When the high-voltage tester detects that the voltage is above 10% of the rated voltage, the alarm module 12 is activated to alarm. It can be concluded from the above that, on the one hand, the integrated circuit board 13 is arranged inside the tester housing 10, and is connected to the alarm module 12 and the connecting electrode 11 respectively. The integrated circuit board 13 and the alarm module 12 are vertically distributed up and down instead of horizontally distributed. Therefore, when subjected to external force, the welding points connecting the integrated circuit board 13 and the alarm module 12 and the connecting electrode 11 are not easy to be disconnected, which is not easy to cause inaccurate test of the tester, and the service life of the tester is increased.

[0044] On the other hand, the contact electrode 11 is arranged on the upper side of the electroscope housing 10, the insulating rod 14 and the alarm module 12 are both arranged on the lower side of the electroscope housing 10, and the alarm module 12 and the insulating rod 14 are distributed left and right. When the insulating rod 14 damages the electroscope housing 10 due to external force, because the alarm module 12 and the insulating rod 14 are distributed left and right, and the alarm module 12 is located on one side of the insulating rod 14 instead of directly above it, it can effectively avoid the occurrence of false triggering, thereby ensuring the accuracy of electroscope detection.

[0045] like Figure 1 As shown, in one embodiment of the present disclosure, the high voltage tester further includes a digital display meter 15;

[0046] The digital display 15 is arranged at the lower side of the electroscope housing 10 and is connected to the alarm module 12 and the integrated circuit board 13 respectively. The digital display 15 is used to display the detected voltage value. The connection between the digital display 15 and the electroscope housing 10 adopts a slot-type fixing method.

[0047] In this embodiment, the digital display 15 is a digital display for displaying the detected voltage value. The digital display 15 displays the voltage value in digital form by receiving the electrical signal processed by the integrated circuit board 13, so that the user can intuitively understand the charged state of the detected object. The digital display 15 has high measurement accuracy and resolution, and can achieve high-precision voltage measurement.

[0048] The digital display 15 is arranged on the lower side of the electroscope housing 10, and is connected to the alarm device and the integrated circuit board 13 respectively. The digital display 15 and the alarm device are adjacent and are both distributed on the same side of the insulating rod 14. This position distribution can reduce the situation where the insulating rod 14 affects the accuracy of the electroscope detection due to external forces. The connection between the digital display 15 and the electroscope housing 10 changes the screw fixing method used in the prior art and selects a slot fixing method. This fixing method is easy to install, simple to disassemble, and more beautiful.

[0049] In one embodiment of the present disclosure, reference Figure 1 , the display accuracy of the digital display meter 15 is 0.01KV.

[0050] In this embodiment, the high-voltage tester in the existing equipment has an audible and visual prompt when the starting voltage is above 10% of the rated voltage, but there is no audible and visual prompt when the residual current is below 10% of the rated voltage. This situation poses a safety hazard to operating and maintenance personnel.

[0051] In this embodiment, a digital display 15 is provided on the lower side of the electroscope housing 10. The digital display 15 can display a three-digit voltage value. Regardless of whether the voltage detected by the electroscope is higher than 10% of the rated voltage, the digital display 15 can dynamically display the voltage value detected by the electroscope. The internationally recognized dividing line AC voltage of high and low voltage electrical appliances is 1KV, and the upper limit of high voltage AC is 750KV. In this embodiment, the display accuracy of the digital display 15 is 0.01KV, which can cover the entire range of high voltage AC.

[0052] In one embodiment of the present disclosure, reference Figure 2 The alarm module 12 includes a light emitting diode 101 and a buzzer 102 both connected to the integrated circuit board 13 .

[0053] In this embodiment, the light emitting diode 101 is a semiconductor material that can convert electrical energy into visible light, and has the advantages of high efficiency, energy saving, and long life. In the alarm system, the light emitting diode 101 is generally used to provide visual indications to remind the user of the working status of the system. For example, when the alarm detects an abnormal situation, the light emitting diode 101 will flash or stay on to remind the user what problem has occurred. In addition, the light emitting diode 101 can also be used to display information such as the power status and signal strength of the alarm. The buzzer 102 is an electronic component that can make a sound, which can drive a small speaker to vibrate through a built-in electromagnetic coil to produce a sound. In the alarm system, the buzzer 102 is generally used to provide audio indications to remind the user of the working status of the system. For example, when the alarm detects an abnormal situation, the buzzer 102 will emit a loud alarm sound to remind the user what problem has occurred. In addition, the buzzer 102 can also be used to play prompt sounds, warning sounds, etc.

[0054] In this embodiment, the alarm module 12 includes a light-emitting diode 101 and a buzzer 102, and both the light-emitting diode 101 and the buzzer 102 are connected to the integrated circuit board 13. When the integrated circuit board 13 detects that the voltage is higher than 10% of the rated voltage, it sends an abnormal signal to the light-emitting diode 101 and the buzzer 102, and the alarm module 12 can realize simultaneous sound and light alarm.

[0055] In one embodiment of the present disclosure, reference Figure 3 , the high voltage electroscope also includes a battery compartment inner shell 16;

[0056] The battery compartment inner shell 16 is arranged inside the electroscope housing 10 , and a battery is installed inside the battery compartment inner shell 16 . The battery compartment inner shell 16 and the electroscope housing 10 are fixed in a slot-type manner. The battery is used to supply power to the integrated circuit board 13 and the alarm module 12 respectively.

[0057] In this embodiment, the battery compartment inner shell 16 is disposed inside the electroscope housing 10, and mainly serves to accommodate and fix the battery. The battery compartment inner shell 16 provides an installation space for the battery, ensuring that the battery is stably placed in the battery compartment to prevent the battery from loosening or being damaged due to factors such as vibration and impact. The battery compartment inner shell 16 can fix the battery through a specific design to prevent the battery from being displaced or rolled during use, thereby ensuring the reliability of the connection between the battery and the integrated circuit board 13 and the alarm module 12.

[0058] The battery compartment inner shell 16 and the electroscope housing 10 are fixed in a slot-type manner, which changes the screw fixing method used in the prior art. This slot-type fixing method is easy to install, simple to disassemble, and more beautiful.

[0059] In one embodiment of the present disclosure, reference Figure 5The integrated circuit board 13 and the electroscope housing 10 are connected by a slot-type fixing method.

[0060] In this embodiment, the connection between the integrated circuit board 13 and the electroscope housing 10 changes the screw fixing method in the prior art and selects a slot-type fixing method, which is easy to install, simple to disassemble, and more beautiful.

[0061] In one embodiment of the present disclosure, the integrated circuit board 13 is provided with a voltage detection sensor, an amplifier circuit and a comparator;

[0062] The amplifier circuit is connected to the voltage detection sensor and the comparator respectively; the voltage detection sensor is connected to the connection electrode 11 , and the comparator is connected to the alarm module 12 .

[0063] In this embodiment, after the voltage detection sensor detects that the object is charged, an electrical signal will be generated, and the size of this electrical signal is proportional to the voltage value of the object. The voltage detection sensor sends the detected electrical signal to the amplifier circuit for amplification, and the amplified electrical signal is compared with a preset threshold in the comparator. The preset threshold is 10% of the rated voltage value. When the electrical signal is less than or equal to the threshold, the voltage value of the object to be detected does not exceed 10% of the rated voltage value, and the integrated circuit board 13 will not issue an alarm signal, but will send the detected voltage value to the digital display 15 for display; when the electrical signal is greater than the threshold, the voltage value of the object to be detected exceeds 10% of the rated voltage value, the integrated circuit board 13 sends an alarm signal, the alarm device turns on the sound and light warning, and sends the detected voltage value to the digital display 15 for display.

[0064] In one embodiment of the present disclosure, the insulating rod 14 is a telescopic insulating rod 14 .

[0065] In this embodiment, the insulating rod 14 is a telescopic insulating rod 14, which can be freely extended and retracted, and is easy to carry and store. The telescopic insulating rod 14 has a high insulation performance and can ensure the personal safety of operators when operating near high-voltage electrical equipment.

[0066] In one embodiment of the present disclosure, reference Figure 4 The connecting electrode 11 and the electroscope housing 10 are fixed by a square hole plus a nut.

[0067] In this embodiment, the connection electrode 11 and the electroscope housing 10 are fixed by a square hole plus a nut, which can prevent the connection electrode 11 and the electroscope housing 10 from falling out due to external force, and can also prevent the connection electrode 11 and the housing from loosening due to left and right rotation, resulting in the connection between the connection electrode 11 and the integrated circuit board 13 being disconnected.

[0068] In one embodiment of the present disclosure, the connection electrode 11 is connected to the integrated circuit board 13 through two leads.

[0069] In this embodiment, the electrode 11 is connected in series with the integrated circuit board 13 through two leads. The electrode 11 of the electroscope can input the charge into the integrated circuit board 13, and the integrated circuit board 13 determines the charged state of the object to be detected. When the voltage value of the object to be detected does not exceed 10% of the rated voltage value, the integrated circuit board 13 will not issue an alarm signal, but will send the detected voltage value to the digital display 15 for display; when the voltage value of the object to be detected exceeds 10% of the rated voltage value, the integrated circuit board 13 will issue an alarm signal, the alarm device will start the sound and light warning, and at the same time send the detected voltage value to the digital display 15 for display.

[0070] It can be seen from the above embodiments that the high-voltage tester provided by the present disclosure can detect the residual voltage of power equipment or lines. When the residual voltage is lower than 10% of the rated voltage, the digital display 15 on the high-voltage tester can display the specific voltage value to remind the operator to pay attention to the live condition of the equipment. The connection mode of the integrated circuit board 13 and the alarm device 12 of the high-voltage tester provided by the present disclosure is vertical connection from top to bottom. When subjected to external force, the welding points of the connection are not easily affected, which can effectively reduce the occurrence of high-voltage tester failure.

[0071] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure 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. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
