Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, and in particular to a temporary grounding device. Background Art

[0002] When conducting tests on electrical equipment, power workers often need to use a lot of special test equipment to test whether the key parameters of electrical equipment are qualified. For electrical equipment engaged in power transmission and conversion, such as transformers, power cables, high-voltage circuit breakers and other equipment, their insulation characteristics and high-voltage resistance parameters are very important. Therefore, special tests are required for their insulation characteristics and high-voltage resistance during factory inspection and regular inspection and troubleshooting in actual operation. During factory inspection, due to the presence of special inspection agencies and venues, the environmental conditions required for the test can be met, and the parameters of electrical equipment can be tested safely and accurately. However, during the operation stage, due to the widespread installation and use of equipment, it is difficult to ensure qualified grounding conditions, temperature (humidity) control required for the test, and a closed or dust-free environment at the site of use. Therefore, field tests have brought great troubles to power workers, especially qualified grounding conditions. On the one hand, the test instruments and equipment require a qualified grounding to ensure normal operation (working grounding); on the other hand, in order to protect the test personnel and on-site equipment, a good grounding is required to achieve protective grounding. In the past, power workers could use the surrounding water pipes to build a temporary grounding, or temporarily install several sets of grounding devices in the surrounding soil and rivers to achieve the grounding required for the test. However, with the development of urbanization, water pipes have become plastic (polyvinyl chloride) water pipes; and soil or some small streams have become concrete floors. A good set of grounding devices has become the primary problem for field workers.

[0003] Therefore, a temporary grounding device is urgently needed to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a temporary grounding device, which can improve the convenience of grounding and improve the safety and rapidity of grounding.

[0005] In order to achieve the above technical effects, the technical solution of the present invention is as follows:

[0006] A temporary grounding device comprises: a mounting member defining a mounting cavity; a grounding input terminal, the grounding input terminal being arranged on the mounting member; a grounding output terminal, the grounding output terminal being arranged at intervals on the mounting member, the grounding output terminal being electrically connected to the grounding input terminal; and a storage unit, the storage unit being arranged in the mounting cavity, the two ends of the storage unit being electrically connected to the grounding input terminal and the grounding output terminal, respectively.

[0007] Furthermore, the temporary grounding device also includes an electroscope, which is arranged in the mounting member and is electrically connected to the storage unit, and is used to detect the amount of charge in the storage unit.

[0008] Furthermore, the mounting member includes a Faraday cage, and the storage unit is disposed in the Faraday cage.

[0009] Furthermore, the temporary grounding device also includes an impedance component, and the grounding output terminal is connected to the grounding input terminal through the impedance component.

[0010] Furthermore, the temporary grounding device also includes a charging mechanism, which is arranged in the installation cavity, and is electrically connected to the storage unit and the grounding output terminal respectively, and the charging mechanism can pre-set charge on the electrical connection channel between the storage unit and the grounding output terminal.

[0011] Furthermore, an interface is provided on the outer wall of the mounting piece, and the charging end of the charging mechanism fits in the interface.

[0012] Furthermore, the temporary grounding device also includes a support member, and the support member is arranged on the bottom wall of the mounting member.

[0014] Furthermore, the ground output terminal is provided in plurality.

[0015] Furthermore, a plurality of ground output terminal arrays are distributed on the mounting member.

[0016] The beneficial effects of the present invention are as follows: according to the temporary grounding device of the present invention, since the storage unit has the effect of rapid charging and discharging, the temporary grounding device can carry the excess electrical energy of the test equipment and can quickly and reliably release its excess electrical energy back to the earth, and there is no need to make requirements on the resistance value of the conductive items electrically connected to the grounding output terminal and the earth, thereby better solving the problem of difficulty in finding qualified grounding conditions on site, so that the test equipment can be safely, quickly and reliably grounded through the temporary grounding device anytime and anywhere.

[0025] Reference below Figure 1The specific structure of the temporary grounding device according to the embodiment of the present invention is described.

[0026] like Figure 1 As shown, Figure 1 A temporary grounding device is disclosed, which includes a mounting member 1, a grounding input terminal 2, a grounding output terminal 3 and a storage unit. The mounting member 1 defines a mounting cavity 11. The grounding input terminal 2 is arranged on the mounting member 1. The grounding output terminal 3 is arranged on the mounting member 1 at intervals, and the grounding output terminal 3 is electrically connected to the grounding input terminal 2. The storage unit is arranged in the mounting cavity 11, and two ends of the storage unit are electrically connected to the grounding input terminal 2 and the grounding output terminal 3 respectively.

[0027] It can be understood that the storage unit has the characteristics of rapid charging and discharging. The charge input by the grounding input terminal 2 can be quickly stored in the storage unit in large quantities, thereby facilitating the rapid and safe transfer of the charge of the test equipment connected to the grounding input terminal 2 to the storage unit. At the same time, the charge in the storage unit can be output to the ground electrically connected to the grounding output terminal 3 through the grounding output terminal 3, thereby being able to safely and effectively release the large-capacity electric energy temporarily stored in the storage unit from the grounding output terminal 3 back to the ground, thereby effectively realizing the grounding of the test equipment when in use.

[0028] Specifically, when in use, the temporary grounding device of this embodiment can electrically connect the grounding input terminal 2 to the test equipment and connect the grounding output terminal 3 to a metal object electrically connected to the earth, thereby realizing a stable and reliable temporary grounding function.

[0029] According to the temporary grounding device of this embodiment, since the storage unit has the effect of rapid charging and discharging, the temporary grounding device can carry the excess electric energy of the test equipment and release its excess electric energy back to the earth quickly and reliably, and there is no need to make requirements on the resistance value of the conductive object electrically connected to the ground output terminal 3 and the earth, thereby better solving the problem of difficulty in finding qualified grounding conditions on site, so that the test equipment can be safely, quickly and reliably grounded anytime and anywhere through the temporary grounding device.

[0030] In some specific embodiments, the storage unit includes a capacitor or a supercapacitor. In other embodiments of the present invention, the storage unit can also be set as a new type of battery, and its specific structure can be determined according to actual needs as long as it can meet the requirements of large-capacity storage and fast storage.

[0031] In some embodiments, Figure 1 As shown, the temporary grounding device further includes an electroscope 4, which is disposed in the mounting member 1 and is electrically connected to the storage unit. The electroscope 4 is used to detect the charge amount of the storage unit.

[0032] It is understandable that the electroscope 4 can detect the amount of charge in the storage unit, so as to facilitate determining whether the storage unit has completed discharge through the ground output terminal 3 before grounding, so as to ensure that the storage unit has sufficient capacity to achieve rapid charging and discharging during the next grounding process.

[0033] In some embodiments, the mounting 1 comprises a Faraday cage, and the storage unit is disposed within the Faraday cage.

[0034] It can be understood that the Faraday cage has an anti-shielding effect, thereby further improving the grounding safety of the temporary grounding device.

[0035] In some embodiments, the temporary grounding device further includes an impedance component, and the grounding output terminal 3 is connected to the grounding input terminal 2 through the impedance component.

[0036] It can be understood that since the resistance value of the temporary grounding device has deviations at different grounding positions, after the impedance component is set in the discharge channel between the grounding input terminal 2 and the grounding output terminal 3 in this embodiment, it can automatically adapt to the resistance value at different grounding positions, thereby better ensuring that a safe and fast discharge effect can be achieved at different grounding positions.

[0037] In some embodiments, Figure 1 As shown, the temporary grounding device also includes a charging mechanism 5, which is arranged in the installation cavity 11. The charging mechanism 5 is electrically connected to the storage unit and the grounding output terminal 3 respectively, and the charging mechanism 5 can preset charges on the electrical connection channel between the storage unit and the grounding output terminal 3.

[0038] It can be understood that, according to the polarity of the electric charge that the temporary grounding device needs to release back to the earth, the charging mechanism 5 can preset the electric charge of opposite polarity in the discharge channel between the grounding input terminal 2 and the grounding output terminal 3, thereby accelerating the attraction of the current on the test equipment, so that the current on the test equipment can flow more quickly into the temporary grounding device, thereby further improving the discharge effect of the temporary grounding device.

[0039] In some embodiments, an interface is provided on the outer wall of the mounting member 1, and the charging end of the charging mechanism 5 fits in the interface.

[0040] It can be understood that, through the above-mentioned structural setting, it is convenient for operators to charge the charging mechanism 5.

[0041] In some embodiments, Figure 1 As shown, the temporary grounding device further includes a support member 6 , which is arranged on the bottom wall of the mounting member 1 .

[0042] It can be understood that the support member 6 can provide a stable supporting effect on the mounting member 1, thereby further improving the placement stability and application scope of the temporary grounding device.

[0043] In some embodiments, Figure 1 As shown, the ground input terminal 2 is arranged on the top wall of the mounting member 1 , and the ground output terminal 3 is arranged on the side wall of the mounting member 1 .

[0044] It can be understood that the above-mentioned structural arrangement can facilitate both the electrical connection between the ground input terminal 2 and the test equipment and the electrical connection between the ground output terminal 3 and the earth.

[0045] In some embodiments, Figure 1 As shown, a plurality of ground output terminals 3 are provided.

[0046] It is understandable that the multiple ground output terminals 3 can divert the charges that need to be discharged by the storage units, so that when the amount of charge that needs to be discharged by the storage units is large, safe, fast and reliable discharge can still be guaranteed, thereby ensuring reliable grounding of the test equipment.

[0047] In some embodiments, Figure 1 As shown, a plurality of ground output terminals 3 are distributed in an array on the mounting member 1 .

[0048] It can be understood that the above distribution method is conducive to improving the convenience of distribution and can also better prevent interference problems between the ground output terminals 3.

[0049] In the description of this specification, the description with reference to the terms "some embodiments", "other embodiments", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0050] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
