Abstract
The invention discloses an audible and visual alarm of a load control terminal. The audible and visual alarm is characterized by comprising a working power supply (1), wherein the positive electrode on a low voltage side of the working power supply (1) is connected with the positive electrode of a passive alarm (3) through a normally open contact of an intermediate relay (2); and the negative electrode on the low voltage side of the working power supply (1) is connected with the negative electrode of the passive alarm (3) through an air switch (4). The audible and visual alarm has a simple structure, and is safe and reliable; moreover, by the audible and visual alarm, user loss can be avoided, a user can be supervised and urged to renew, the good-quality service level is improved and orderly power utilization is promoted.
Description
Technical field
The invention discloses a kind of negative control terminal audible-visual annunciator, belong to electric system power transformation operation field.
Background technology
At present; In order further to strengthen demand Side Management; Improve using electricity wisely, safety utilization of electric power and ordered electric working level, power department 100 kilovolt-amperes and above power transformer user's electric quantity acquisition terminal all be replaced by having tripping operation forward purchasing electric work can negative control electric quantity acquisition terminal.
At present the user to pay electric weight in advance fast when not enough, notify the user through SMS or phone, remind the user to continue to pay dues.There are two drawbacks in this mode: the one, and present power information acquisition system does not also possess real-time supervisory user electricity charge remaining sum and adds up which demand charge function that Sorry, your ticket has not enough value; This regularly carries out manual monitoring to each household with regard to needing great amount of manpower, because the reason of " manpower " and " regularly " just can cause monitoring not in place.The 2nd, the user operator on duty is fixing, the mobile phone arrearage, and sense of responsibility is not enough etc., and reason can not in time continue to pay dues.These two kinds of drawbacks can both cause unnecessary mistrip, bring unnecessary loss to the user, and then have influenced the enthusiasm that the user continues to pay dues.
2. in peak times of power consumption, when starting the ordered electric emergency preplan, the function because the terminal does not give warning in advance, the user does not have enough setup times, and the user is not ready, and at this time user's tripping operation just causes loss easily.
3. do not have early warning before the present terminal tripping operation, and alarm on the market and terminal do not match, and can not directly be applied on the terminal.
Therefore for making the terminal before tripping operation, have warning function, a kind of alarm is demanded research and development urgently.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art and provide a kind of simple in structure, safe and reliable, can avoid the user to lose, supervise the user to continue to pay dues, improve the good service level, promote the negative control terminal audible-visual annunciator of ordered electric.
The object of the invention can reach through following measure: a kind of negative control terminal audible-visual annunciator; It is characterized in that it comprises working power; The anodal normal opened contact through auxiliary reclay of the low-pressure side of working power links to each other with the positive level of passive alarm, and the low-pressure side negative pole of working power links to each other with the negative level of passive alarm through air switch.
The present invention compares with prior art can produce following good effect: the job specification that the present invention is directed to high pressure user shift electrician can not satisfy the technical goal of collecting the electricity charge and good service in advance with single bulk SMS; After installing the present invention additional on the original equipment, can send the early warning of tangible sound and light; In time remind user's electricity payment to avoid causing damage; And then improve user's enthusiasm that continues to pay dues, and do not need great amount of manpower regularly each household to be carried out manual monitoring, saved a large amount of manual works.Because it has the function of giving warning in advance, when power department starts the ordered electric emergency preplan, prepare to the user the sufficient time, this just improves the enthusiasm that the user cooperates with power department.The present invention is simple in structure, safe and reliable, can avoid the user to lose, and the service of raising advantage, ordered electric reduce holder and take arrearage, save manual work.
Description of drawings:
Fig. 1 is a structural representation of the present invention
Fig. 2 is an electrical schematic diagram of the present invention.
Embodiment: elaborate below in conjunction with the embodiment of accompanying drawing to invention:
Embodiment: a kind of negative control terminal audible-visual annunciator (referring to Fig. 1, Fig. 2); It comprises working power 1; The anodal normal opened contact through auxiliary reclay 2 of the low-pressure side of working power 1 links to each other with the positive level of passive alarm 3, and the low-pressure side negative pole of working power 1 links to each other with the negative level of passive alarm 3 through air switch 4.
Principle of work: being applied in high pressure 100V terminal with the negative control terminal audible-visual annunciator is example: during use; The high-pressure side positive pole of working power 1 is connected on 2 terminals of negative control terminal 5; The high-pressure side negative pole of working power 1 is connected on 5 terminals of negative control terminal 5, and the normal opened contact of auxiliary reclay 2 is connected on 19 and 20 terminals of negative control terminal 5.
The negative control terminal audible-visual annunciator is after the laboratory bug check is out of question; The scene is connected with negative control terminal and debugs; The terminal is built account and is imported paying the electricity charge in advance and early warning electricity charge value being set of user in SG186 marketing system system; Be synchronized to the power information acquisition system, information acquisition system is issued to on-the-spot negative control terminal paying the electricity charge and early warning electricity charge value in advance.When the residue in the negative control terminal is paid electricity charge value in advance when reaching the early warning electricity charge value of setting; Negative control terminal 5 bosom actuating of relay normal opened contacts are closed; 19 and 20 terminals of negative control terminal 5 are exported a direct current 5V signal, and normal opened contact was closed after the auxiliary reclay 2 of negative control terminal audible-visual annunciator received this signal, the low-pressure side positive pole of the working power 1 of negative control terminal audible-visual annunciator and the anodal conducting of passive alarm 3; Passive alarm 3 receives 12V voltage, sends the warning of sound and light.
Claims (1)
1. negative control terminal audible-visual annunciator; It is characterized in that it comprises working power (1); The anodal normal opened contact through auxiliary reclay (2) of the low-pressure side of working power (1) links to each other with the positive level of passive alarm (3), and the low-pressure side negative pole of working power (1) links to each other with the negative level of passive alarm (3) through air switch (4).
