Description

Technical Field

[0001] The present invention relates to the technical field of electric energy meters, in particular to an active isolation type electric energy meter. Background Art

[0002] An energy meter is a meter used to measure the amount of electrical energy consumed. It records the amount of electrical energy flowing in a circuit over a certain period of time, usually in kilowatt-hours (kWh), which is what we often call "degrees". Energy meters are indispensable equipment in power systems and are widely used in industrial, commercial and residential areas to measure, record and settle electrical energy consumption.

[0003] With the development of the market economy and the improvement of people's living standards, people's electrical equipment is also increasing. In a high temperature environment, when the current used by the electrical appliances exceeds the bearing range of the wires, it will cause the connection of the energy meter to overheat, which will eventually cause the line energy meter to catch fire. In addition, when a short circuit occurs, electric sparks will instantly be generated at the wire connection of the energy meter. The above two situations are extremely likely to cause fires, and generally the energy meters are set in inconspicuous positions. When overload or short circuit causes the connection of the energy meter to overheat and cause a fire, people may not have time to discover this situation. At this time, if the power supply is not cut off in time and the fire is not extinguished at the connection, it will be extremely easy to cause a fire.

[0004] For this purpose, an active isolation type electric energy meter is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an active isolation type electric energy meter, which solves the problem that when the current used by the electrical appliance exceeds the bearing range of the wires, the connection points of the electric energy meter will overheat, thereby causing fire at the connection points of the electric energy meter, and the problem that a short circuit causes fire at the connection points of the electric energy meter. The present invention can physically cut off the electrical connection between the wire and the electric energy meter in time when the temperature at the connection point of the electric energy meter is too high, or a short circuit causes a fire, and quickly separate and isolate the wire from the connection terminal, thereby preventing the connection point from continuing to catch fire and heat up, and during the separation process, the fire can be extinguished at the fire point to prevent the spread of the fire.

At this time, the push plate 935 and the connecting column 936 will automatically fall to their original positions under the action of gravity to facilitate the use of the next fire extinguishing work.

[0046] Furthermore, a push piece 11 is provided on the push plate 935; the push piece 11 includes a push rod 111 fixedly connected to the push plate 935, and an upper cover 112 rotatably connected to the top of the telescopic column 921; the upper cover 112 can isolate the fire extinguishing dust from the outside to prevent the fire extinguishing dust from getting wet.

[0047] When in use, when the temperature at the connection sleeve 3 is too high or a fire occurs, the trigger rope 48 will be melted, and the limit column 46 will be pushed by the elastic member 1 45 to move into the circular sleeve 41.

[0049] Reference Fig.12 , which is the third embodiment of the present invention, and is different from the previous two embodiments in that: it also includes a blowing member 12, and two groups of blowing members 12 are also provided on the connecting shell 5, and the two groups of blowing members 12 are respectively installed on both sides of the connecting shell 5; the blowing member 12 includes a fixed shell 121 fixedly connected to the outside of the connecting shell 5, a telescopic airbag 122 fixedly connected to the fixed shell 121, and a pressure frame 123 fixedly connected to the telescopic airbag 122; the pressure frame 123 is in a right angle shape, and the other end of the pressure frame 123 is fixedly connected to the bottom plate 7; the blowing member 12 can blow out gas when the dust is pushed out, which plays a role in dispersing the fire extinguishing and promoting the fire extinguishing effect.

[0050] Furthermore, a nozzle 124 is fixedly connected to the isolation plate 81; there are four groups of nozzles 124, which are respectively distributed at the four corners of the isolation plate 81; a connecting pipe 125 is fixedly connected between the nozzle 124 and the bottom of the telescopic airbag 122; wherein every two groups of nozzles 124 are connected to one group of telescopic airbags 122, and the connection position is located at the bottom of the airbag.

[0051] During use, when the fire extinguishing dust is pushed out, since the upper end of the pressure frame 123 is fixedly connected to the telescopic airbag 122 and the lower end is fixedly connected to the bottom plate 7, the telescopic airbag 122 will be squeezed by the pressure frame 123 during the spraying of the fire extinguishing dust, causing the gas to be sprayed out from the nozzle 124. The sprayed gas can disperse the sprayed fire extinguishing dust, thereby promoting the fire extinguishing effect.

[0052] Working principle: Refer to Figure 1-12When the temperature at the connection sleeve 3 is too high or a fire occurs, the trigger rope 48 will be melted, and the limit column 46 will be pushed by the elastic member 1 45 to move into the circular sleeve 41. At this time, the limit column 46 on the conductive column 914 will be released, and the conductive column 914 will be pushed by the elastic member 3 923 to shrink into the connection shell 5, and the telescopic column 921 and the telescopic sleeve 922 will also open accordingly. In this process, the switching column 9311 will be at one end against the rectangular opening 931, so the telescopic sleeve 922 moving downward will drive the push column 9311 to move to the right side of the rectangular opening 931. The sleeve 938 descends and causes the elastic member 939 to accumulate force and compress. When the fixed plate 9313 that descends to the switching column 9311 abuts against the inclined block 9314, the abutting plate will push the switching column 9311 along the inclined surface of the inclined block 9314 to abut against the abutting groove 937. At this time, the switching column 9311 will release the abutment with the rectangular opening 931. At this time, the conductive column 914 also completely enters under the isolation plate 81, and at this time, the push sleeve 938 and the connecting column 936 are in an extended state. Therefore, the elastic member 939 after accumulating force will The push sleeve 938 and the connecting column 936 are pushed upward quickly, and the push rod 111 will also push the upper cover 112 open, so that the push plate 935 will push the fire extinguishing dust out of the storage chamber 933 to extinguish the fire at the connecting sleeve 3, and in this process, the telescopic airbag 122 will also be squeezed by the pressure frame 123, so that the gas is ejected from the nozzle 124, and the ejected gas can blow away the ejected fire extinguishing dust, thereby promoting the fire extinguishing effect, and after the fire extinguishing dust is ejected, the switching column 9311 will be located at the top of the moving groove 932 At this time, the pushing frame 102 will abut against the switching groove 9312. When the fire extinguishing element 93 needs to be used again after completing the fire extinguishing work, the bottom plate 7 can be pushed to shrink the telescopic column 921 and the telescopic sleeve 922. At this time, the telescopic sleeve 922 moved upward to the top will drive the contact plate 103 to push the pushing frame 102 to rotate. The rotating pushing frame 102 will push the switching column 9311 to abut against the rectangular opening 931. At this time, the pushing plate 935 and the connecting column 936 will automatically fall to their original positions under the action of gravity to facilitate the use of the next fire extinguishing work.
