Abstract
The invention discloses an anti-overburning single-phase energy meter. The single-phase energy meter comprises a single-phase energy meter body and a small temperature sensor, wherein the small temperature sensor is connected with a central processing unit (CPU) of the single-phase energy meter. In the single-phase energy meter, the small temperature sensor is arranged in a current terminal at the tail of the single-phase energy meter; the value of the small temperature sensor is set at 90 degrees according to the heat resistance value of a bakelite at the tail of the single-phase energy meter, wherein the heat resistance value is about 135; when the value of the small temperature sensor is more than 90 degrees, a node of the small temperature sensor is closed; the value of the small temperature sensor is directly transmitted to the CPU of the single-phase energy meter; a trip signal is emitted by the CPU of the energy meter and directly applied to an internal control switch of the single-phase energy meter; an instruction that 'trip is caused by over-high temperature at the tail of the meter' is displayed on a liquid crystal screen of the energy meter at the same time, so that a connection circuit at the tail of the meter is convenient to examine and repair; and the fault trip reason can be also embodied in a remote electric energy acquisition system. Therefore, the energy meter can be effectively prevented from being burned and safety and stability of a transmission line are effectively guaranteed.
Description
Technical field
The invention belongs to the electric energy meter technical field, be specifically related to a kind of anti-single-phase electric energy meter that burns.
Background technology
In the daily power supply, because single-phase electric energy meter table tail connects unreliable and wire diameter is not enough, the current-carrying capacity deficiency, cause the lead heating serious, heat conduction causes single-phase electric energy meter table tail temperature too high to reasons such as table tails, thereby the single-phase electric energy meter that causes low-voltage distribution network burns frequent existence, the cost of burning electric energy meter along with the adding of intelligent electric meter function is also strengthening, sometimes a single-phase electric energy meter burns, even cause burning of telecommunication terminal and other consumers, cause power failure, had a strong impact on power supply reliability, cause manpower, material resources, the very big loss of financial resources.And at present, prevent that effectively the single-phase electric energy meter that burns seldom.
Summary of the invention
The objective of the invention is to avoid above-mentioned weak point of the prior art, and provide a kind of and can prevent effectively that electric energy meter from burning, safety and stability, effectively protect the anti-single-phase electric energy meter that burns of transmission line of electricity.
Realize that the technical scheme that purpose of the present invention adopts is: a kind of anti-single-phase electric energy meter that burns, comprise single-phase electric energy meter body and mini-temperature sensor, described mini-temperature sensor is arranged on the table tail current terminal inside of single-phase electric energy meter body, described mini-temperature sensor is connected with single-phase electric energy meter CPU, described single-phase electric energy meter body is provided with the internal control switch, and described single-phase electric energy meter body is provided with LCD Panel.
Because the present invention is provided with mini-temperature sensor with the table tail current terminal inside of single-phase electric energy meter, according to the heat-resisting value of table tail bakelite roughly about 135 degree, 90 degree that are set at mini-temperature sensor, when surpassing 90 degree, the node closure of mini-temperature sensor, directly reach on the CPU of single-phase electric energy meter, CPU by electric energy meter sends trip signal, and directly act on the internal control switch of single-phase electric energy meter, on the LCD Panel of electric energy meter, show the indication of " the too high tripping operation of table tail temperature " simultaneously, to make things convenient for repair sheet tail connection line, simultaneously, in the system of remote power collection, also can embody this fault trip reason.The beneficial effect that brings like this is: when the single-phase electric energy meter table tail automatic tripping switch to a certain degree time that generates heat, can prevent effectively that electric energy meter from burning, and effectively protects the safety and stability of transmission line of electricity.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described:
Fig. 1 is a circuit diagram of the present invention.
Embodiment
As shown in Figure 1: a kind of anti-single-phase electric energy meter that burns, comprise single-phase electric energy meter body 1 and mini-temperature sensor 2, described mini-temperature sensor 2 is arranged on table tail current terminal 4 inside of single-phase electric energy meter body 1, described mini-temperature sensor 2 is connected with single-phase electric energy meter CPU3, described single-phase electric energy meter body 1 is provided with the internal control switch, and described single-phase electric energy meter body 1 is provided with LCD Panel.
Utilize the present invention, table tail current terminal 4 inside of single-phase electric energy meter body 1 are provided with mini-temperature sensor 2, according to the heat-resisting value of table tail bakelite roughly about 135 degree, 90 degree that are set at mini-temperature sensor 2, when surpassing 90 degree, the node closure of mini-temperature sensor 2, directly reach on the single-phase electric energy meter CPU3, CPU3 sends trip signal by single-phase electric energy meter, and directly act on the internal control switch of single-phase electric energy meter, on the LCD Panel of single-phase electric energy meter, show the indication of " the too high tripping operation of table tail temperature " simultaneously, to make things convenient for repair sheet tail connection line, simultaneously, in the system of remote power collection, also can embody this fault trip reason.Like this, when the single-phase electric energy meter table tail automatic TRIP to a certain degree time that generates heat, can prevent effectively that electric energy meter from burning, and effectively protects the safety and stability of transmission line of electricity.
