Abstract
The utility model relates to a low-voltage leakage circuit breaker, comprising a central processor, a power supply module, a leakage detection module and a leakage current comparison module arranged on one end of the central processor, and an alarm device and a breaker control module arranged on the other end of the central processor, wherein the leakage current comparison module is in electrical connection with the alarm device through the central processor so as to make the alarm device emit alarm signals. The low-voltage leakage circuit breaker of the utility model is provided with the alarm device so as to avoid safe accidents and economic losses caused by sudden supply interruption.
Description
[technical field]
The utility model relates to a kind of low pressure RCCB, belongs to the low voltage electrical apparatus technology field.
[background technology]
At present, RCCB generally has been installed in the low voltage electric network.RCCB can effectively prevent the fiery residence, device damage and the human casualty accident that cause because of electric leakage, and its operation principle is: when leakage current surpassed the rated current of circuit breaker, RCCB was cut off the electricity supply automatic trip.
Yet also there are some defectives in the RCCB of prior art, can't send the tripping operation early warning signal like it, when it is cut off the electricity supply suddenly, causes security incident and economic loss easily.
For solving the problems of the technologies described above, necessary a kind of structure improved low pressure RCCB that has is provided, to overcome said defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of the utility model is to provide a kind of low pressure RCCB that can send alarm signal.
For realizing above-mentioned purpose; The technical scheme that the utility model is taked is: a kind of low pressure RCCB; It comprises central processing unit; Be arranged on supply module, detection of electrical leakage module, the leakage current comparison module of central processing unit one end, and the warning device and the circuit breaker control module that are arranged on the central processing unit other end; Wherein, said leakage current comparison module electrically connects through central processing unit and warning device, makes warning device send alarm signal.
The low pressure RCCB of the utility model further is set to: on said central processing unit, be connected with a display module.
Compared with prior art, the utlity model has following beneficial effect: the low pressure RCCB of the utility model is through being provided with a warning device, thereby avoids cutting off the electricity supply suddenly and cause security incident and economic loss.
[description of drawings]
Fig. 1 is the structure chart of the low pressure RCCB of the utility model.
[embodiment]
See also shown in the Figure of description 1; The utility model is a kind of structure improved low pressure RCCB that has; It is by central processing unit 1; Be arranged on supply module 2, detection of electrical leakage module 3, the leakage current comparison module 4 of central processing unit 1 one ends, and the elements such as warning device 5 and circuit breaker control module 6 that are arranged on central processing unit 1 other end electrically connect and form.
Wherein, said supply module 2 is used to import low voltage voltage.Said detection of electrical leakage module 3 is used to detect the leakage current of supply module 2.Said leakage current comparison module 4 is used for the comparison magnitude of leakage current and whether belongs to safe condition, and it electrically connects through central processing unit 1 and warning device 5, makes warning device 5 send alarm signal, notes with reminds people.
On said central processing unit 1, further be connected with a display module 7, it can show numerical value such as electric current, voltage, leakage current in real time.
The operation principle of the low pressure RCCB of the utility model is following: detection of electrical leakage module 3 detects leakage current, and the relatively judgement through leakage current comparison module 4 determines whether and need cut off the electricity supply.If when leakage current surpassed the rated value of leakage current comparison module 4 settings, it sent signal through central processing unit 1 and gives warning device 5, makes warning device 5 send alarm signal.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection range of this creation.
