The live indicator lamp 32 is in signal connection with the voltage measuring module 31, the voltage measuring module 31 controls the on-off, and when the voltage measuring module 31 measures and calculates the voltage, the live indicator lamp 32 is controlled to be on to prompt a user that electricity exists.

In the foregoing embodiment, the voltage sensing device 33 is used for sensing an electromagnetic field and calculating a current flowing through the T-shaped quick connector, and there are other embodiments such as an oscillating circuit for measurement.

In order to balance the accuracy of the cost, in some preferred embodiments, the voltage sensing device 33 mainly includes a metal sensing terminal, the metal sensing terminal is set to have different shapes according to the preset intensity of the current to be measured, in a general case, the metal sensing terminal is a metal ring embedded inside the insulating bolt 222, the shapes and distances of the interfaces between the metal sensing terminal and the T-type fast plug terminal 22 are constant, so that the induced voltages generated by the currents with the same magnitude are also the same, and the metal sensing terminal is grounded through the voltage measuring module 31 to generate a current, so that the corresponding relationship can be recorded in the voltage measuring module 31 according to the point, and the intensity of the current flowing in the T-type fast plug terminal 22 can be reversely calculated.

The application also provides an embodiment of the emergency high-voltage cable branch box, which comprises a box body 1, a strong electric component and the pressure-measuring high-voltage live display device, as shown in fig. 1 and fig. 2.

The box body 1 is a square box body, the side surface of the box body is provided with a grounding device 11, and the box body needs to be grounded when the embodiment is used in most cases.

And the strong electric assembly 2 comprises at least one multi-gang sleeve 21 and a plurality of T-shaped quick plugs.

In the pressure measuring high-voltage live display device, one branch port of a T-shaped quick plug is plugged into a multi-gang sleeve 21, the T-shaped quick plugs are electrically connected through the multi-gang sleeve 21, in a general embodiment, an electrical connection plug is mounted at the bottom of the multi-gang sleeve 21, the electrical connection plug is communicated through a circuit embedded in the multi-gang sleeve 21, in some embodiments, some T-shaped quick plugs can be selectively combined into one group to be communicated with each other according to needs, and the groups are not communicated with each other, so that a blocking type working mode is realized.

In a general embodiment, the voltage measuring module 31 has a plurality of functions of transmitting measured data out, such as remote communication or liquid crystal display, and in the embodiment shown in fig. 1, a part of the voltage measuring module is embedded in the side wall of the box body 1, and protrudes outward, and can be used as a display screen to display specific values of voltage.

In the implementation process of the inventor, the whole box body 1 is used in the early stage, and in the application process, the circuit in the box body 1 often causes the decomposition of gas or thermal expansion, so that the box body 1 is often required to be disassembled for maintenance, and sometimes the T-shaped quick-plugging terminal 22 is also required to be disassembled and assembled according to the actually measured circuit, and the box body 1 is also required to be opened frequently.

In order to solve the problem, in some preferred embodiments, the box body 1 is divided into two parts, namely a top cover and a bottom box 13, the top cover and the bottom box 13 are detachably connected through at least three buckles 14, so that the top cover and the bottom box 13 can be conveniently and quickly separated, and workers can conveniently disassemble and assemble the box body for use. In some embodiments, a hinge is further provided on the basis of the buckle 14, so that the top cover and the bottom case 13 are hinged, the loss of components is avoided, and the opening and closing are controlled by the buckle 14.

However, the case 1 is divided into two parts, which causes a certain sealing problem, and particularly in a rainy environment, water easily flows into the case 1 through a gap between the top cover and the bottom case 13, causing various damages such as short circuit.

To solve this problem, in some preferred embodiments, the top edge of the top cover protrudes outward to form a rain edge 121, which prevents water drops from sliding off the outer wall surface of the case 1.

T type quick connector in the box 1 and the connection of the row's of more sleeve pipes 21 are not necessarily very inseparable, simultaneously, because mainly still there is the high-pressure part in the box 1, consequently the heat that the electric current circulation produced is received to gas wherein can cause the inflation, in the long-term use, often too late to open box 1 and exhaust, and because waterproof problem usually between top cap and the end box 13, it is comparatively inseparable to connect, and gas can' T in time be got rid of, therefore inclosed box 1 has certain explosion risk.

In some preferred embodiments, the outer side wall of the top cover is provided with the explosion-proof vent valve 122, and in some embodiments, the explosion-proof vent valve 122 is provided on the side wall of the bottom box 13, but the explosion-proof vent valve 122 of such embodiments also often faces the problem of rain erosion. Therefore, the explosion-proof air-permeable valve 122 is arranged on the outer side wall of the top cover and is tightly attached to the bottom surface of the rain edge 121, and the water permeation is reduced to the maximum extent.

In practice, the inventor finds that the box 1 is frequently electrified when current is induced by the box 1, particularly when the voltage reaches a certain level, so for safety, in some preferred embodiments, the T-shaped quick-plug terminal 22 only extends from two opposite sides, and the remaining two opposite sides are provided with the built-in insulated handles 15, so that the box 1 can be conveniently transferred when cables are connected.

In the foregoing embodiment, the voltage measuring module 31 can only use various display devices with good resolution when operating in a weak current environment, so that the voltage measuring module 31 cannot be directly connected to a high-voltage line to obtain power, and generally needs to be connected to a weak current power supply line. For portability, in some preferred embodiments, the voltage measurement module 31 is built in with a battery to reduce the requirement for external power conditions.

The application also provides an embodiment of an emergency high-voltage cable branching device, as shown in fig. 4, the emergency high-voltage cable branching device comprises at least three pressure-measuring high-voltage live display devices which are arranged in common with each other and used for measuring a multi-phase circuit at one time, and meanwhile, the adjacent grounding devices 11 are connected, so that the measurement consistency is improved.

In order to distinguish conveniently, different emergency high-voltage cable branch boxes in the same emergency high-voltage cable branch device are painted with different colors, and the colors of the different emergency high-voltage cable branch boxes are generally consistent with the colors of the three-phase cables, so that workers can conveniently connect the cables, and mistakes are avoided.
