Abstract
The utility model discloses a simple electric energy meter testing device which comprises a power supply input socket, a power supply input plug, an electric energy meter, a current leakage protector and a power supply output socket, wherein two ends of the electric energy meter are connected with the power supply input plug and the power supply input socket respectively; the current leakage protector is connected in series between the electric energy meter and the power supply output socket; and one end of the power supply input socket is in matching connection with the power supply input plug, and the other end of the power supply input socket is provided with a lead. The simple electric energy meter testing device provided by the utility model is simple in structure and low in cost; a user can read the electricity utilization of power consumption appliances visibly and judge whether the meter is accurate or not, thereby improving the satisfaction of the user in on-site regulation.
Description
[technical field]
The utility model relates to calibrator for watt-hour meter, especially easy to use, the calibrator for watt-hour meter that is easily understood.
[background technology]
The main task of power customer service centre is carried out service for the user exactly.Making " Sunshine Service " brand, carrying out all activities such as the civilized hilllock of the satisfied woman that the station is built, created of basic unit of the masses all is to serve quality better service client in order to promote self.And the customer satisfaction rate is an explanation electrical power services high-quality whether important indicator.
The correlation study statistics shows, on-the-spot lieutenant colonel to be evaluated as general or relatively poor situation a lot, directly influenced the satisfaction rate of " Sunshine Service ".And the client estimates relatively poor main cause to on-the-spot lieutenant colonel and is that work for inspection is professional too strong, directly causes the user result that can't accept inspection, thereby causes the distrust of service and dissatisfied.
[utility model content]
The purpose of the utility model solves the problems of the prior art exactly; A kind of simple and easy calibrator for watt-hour meter is proposed; The electricity consumption situation that can make the user read power consumption electrical equipment very intuitively, and accurately whether can accurately judge table meter, thus improve the satisfaction of user to on-the-spot lieutenant colonel.
For realizing above-mentioned purpose; The utility model provides a kind of simple and easy calibrator for watt-hour meter; Comprise power input socket, power input plug, electric energy meter, earth leakage protective device and power output socket, the two ends of said electric energy meter are connected respectively to power input plug and power output socket, are in series with earth leakage protective device between electric energy meter and the power output socket; One end and the power input plug of power input socket are connected, and the other end is provided with lead.
As preferably, also comprise connection terminal, said earth leakage protective device is connected to connection terminal, is connected to power output socket by connection terminal again, and is safe in utilization, easy to connect.
As preferably, also comprise installing plate, said power input plug, electric energy meter, earth leakage protective device and power output socket are installed on the installing plate, and cost is low, and is easy to carry.
As preferably, the top of said installing plate is provided with and articulates flexible cord, places and easy to operate.
As preferably, also comprise box body, said power input plug, electric energy meter, earth leakage protective device and power output socket are installed in the box body, and be attractive in appearance, safe.
The beneficial effect of the utility model: the utility model is simple in structure, and cost is low, the electricity consumption situation that can make the user read power consumption electrical equipment very intuitively, and accurately whether can accurately judge table meter, thus improve the satisfaction of user to on-the-spot lieutenant colonel.
Characteristic of the utility model and advantage will combine accompanying drawing to be elaborated through embodiment.
[description of drawings]
Fig. 1 is the structural representation of the simple and easy calibrator for watt-hour meter of the utility model.
[embodiment]
As shown in Figure 1; Adopt installing plate 6 or box body to install; Comprise power input socket 2, power input plug 3, electric energy meter 4, earth leakage protective device 7, connection terminal 9 and power output socket 8, the two ends of said electric energy meter 4 are connected respectively to power input plug 3 and power output socket 8, are in series with earth leakage protective device 7 between electric energy meter 4 and the power output socket 8; One end and the power input plug 3 of power input socket 2 are connected; The other end is provided with lead 1, and earth leakage protective device 7 is connected to connection terminal 9, is connected to power output socket 8 by connection terminal 9 again.For making things convenient for execute-in-place, can establish at the top of installing plate 6 and articulate flexible cord 5, the staff directly is articulated in whole device on hook or the nail and can uses fast.Electric energy meter 4 can adopt DDS71 type electronic type single-phase AC active electric energy meter 4, and it is the multiply copper core of 2.5mm that the electrical connection between the individual parts can be adopted diameter, and cost is low, connects reliably, and realizes conveniently.
When the user need measure the degree of accuracy that oneself shows to count; User's earth leakage protective device 7 leading-out terminals are advanced in the series connection of this device; Can relatively settle in a foreign country or in another city what of error of table meter and our standard spreadsheet (this device) at civilian family oneself of the measurement of carrying out a period of time can let the resident understand the accuracy that oneself shows to count intuitively.When the user need understand the actual power consumption amount of every electrical equipment in oneself electrical equipment, power input socket 2 is taken off from power input plug 3, power input plug 3 is inserted user's wiring board; To be inserted power output socket 8 by the plug of electricity measurer; Can measure in a period of time,, thereby let the user where understand main power consumption point by the electricity consumption situation of electricity measurer (as: refrigerator, computer etc.); Thereby understand the reason of power consumption size, improve its satisfaction electrical power services enterprise.
The foregoing description is the explanation to the utility model, is not the qualification to the utility model, any protection domain that scheme after the utility model simple transformation is all belonged to the utility model.
