Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of electric power systems, and in particular relates to a three-phase inductive meter-changing short-circuiting tool. Background Art
[0002] The replacement of direct three-phase electric energy meters is basically done by power outage. The power outage process will cause inconvenience to users, and some users (such as Internet cafes, medical clinics, aquaculture farmers, etc.) will also suffer economic losses. According to the user needs and current status of the above-mentioned various electric energy meters without power outage, the installation site of the electric energy meter was investigated. It was found that a large number of users who installed direct three-phase electric energy meters in the early stage could not achieve the replacement of meters without power outage. Therefore, it is particularly necessary to provide an economical meter replacement device to achieve the replacement of meters without power outage. Summary of the invention
[0003] The purpose of the present invention is to provide a three-phase non-inductive meter-changing short-circuiting tool to solve the problems existing in the background technology.
[0004] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a three-phase inductive meter-changing short-circuit tool, comprising a base plate, an input copper bar, an output copper bar, a connecting copper plate and a spring, wherein the base plate is provided with an input copper bar slot and an output copper bar slot, and a spring positioning hole is provided between the input copper bar slot and the output copper bar slot, the input copper bar is inserted into the input copper bar slot and fixed to the base plate by a copper bar fixing piece, the output copper bar is inserted into the output copper bar slot and fixed to the base plate by a copper bar fixing piece, the spring is placed in the spring positioning hole, the connecting copper bar is located at the upper part of the input copper bar and the output copper bar, connecting screws are respectively provided at both ends of the connecting copper bar, the two connecting screws respectively pass through the through holes on the input copper bar and the output copper bar and are threadedly connected with the corresponding threaded holes on the input copper bar slot and the output copper bar slot, one end of the input copper bar and the output copper bar is connected to the electric meter, and the other end is connected to the main air switch and the user output air switch.
[0005] Preferably, the base plate and the connecting screws are both made of insulating materials.
[0006] Preferably, the input copper busbar and the output copper busbar are respectively three groups, namely a neutral wire, a live wire and a ground wire.
[0007] Preferably, the bottom plate is pre-installed in the electric meter box or outside the electric meter box.
[0008] Preferably, there are at least two springs arranged in parallel.
[0009] The beneficial effects of the present invention are as follows: the design has a reasonable structure and strong processability, which enables operators to safely load, unload and replace the energy meter, and also plays a role in safety. Tightening the screws temporarily short-circuits the energy meter. Under the premise of not affecting the normal power supply and use of users, the relevant staff of the power supply company can safely replace the meter. This largely avoids a series of problems caused by power outages for customers due to meter replacement, and greatly reduces customers' power outage complaints. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 is a system block diagram of the present invention;
[0011] Figure 2 is an enlarged view of the bottom plate of the present invention;
[0012] Figure 3 It is a cross-sectional view of the bottom plate of the present invention. DETAILED DESCRIPTION
[0013] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings and preferred embodiments.
[0014] like Figure 1-3 As shown, a three-phase non-inductive meter changing short-circuit tool comprises a base plate 2, an input copper bar 4, an output copper bar 10, a connecting copper plate 6 and a spring 8. An input copper bar groove 12 and an output copper bar groove 13 are provided on the base plate, and a spring positioning hole 14 is provided between the input copper bar groove and the output copper bar groove. In order to make the connecting copper plate move more smoothly and prevent a single spring from losing its elastic force for a long time, the springs described in the present invention are at least two parallel ones. The input copper bar is inserted into the input copper bar slot and fixed on the bottom plate by the copper bar fixing member 5, the output copper bar is inserted into the output copper bar slot and fixed on the bottom plate by the copper bar fixing member 5, the spring is placed in the spring positioning hole, the connecting copper bar is located on the upper part of the input copper bar and the output copper bar, and the two ends of the connecting copper bar are respectively provided with connecting screws 7, and the two connecting screws pass through the through holes on the input copper bar and the output copper bar and are threadedly connected with the corresponding threaded holes on the input copper bar slot and the output copper bar slot, and by adjusting the connecting screws, the movement of the connecting copper bar up and down under the action of the spring pad can be controlled, so that the connecting copper plate is in contact with or separated from the input copper bar and the output copper bar. One end of the input copper bar and the output copper bar is connected to the electric meter 9, and the other end is connected to the air switch main switch 1 and the user output air switch 11 through the terminal 3.
[0015] In order to prevent the input copper busbar and the output copper busbar from short-circuiting directly through the bottom plate and the connecting screws, in the present invention, the bottom plate and the connecting screws are both made of insulating materials.
[0016] In the present invention, according to actual usage, the input copper busbar and the output copper busbar are respectively divided into three groups, namely a neutral wire, a live wire and a ground wire.
[0017] Furthermore, in the present invention, the bottom plate is pre-installed in the electric meter box or outside the electric meter box.
[0018] After the connecting screws are tightened, the connecting screws press the connecting copper plate 6 downward, and the two ends of the connecting copper plate overcome the elastic force of the spring and are connected to the input copper bar and the output copper bar respectively, forming a short circuit between the input copper plate and the output copper plate. At this time, the main air switch is directly connected to the user's output air switch through the input copper bar and the output copper plate to form a loop to separate the electric meter, so that the electric meter can be replaced without power outage. After replacing the new electric meter, loosen the connecting screws above the input copper bar and the output copper bar. Under the action of the spring, the connecting copper plate pops up, and the two ends of the connecting copper plate are separated from the input copper bar and the output copper bar. At this time, the current passes through the input air switch and then is connected to the new electric meter through the input copper bar, and then passes through the new electric meter and enters the user's output air switch through the output copper bar.
[0019] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
