Abstract
The utility model introduces an electric stored timer for mobile power devices, which is composed of a voltage transformation rectification controlling circuit, a relay start-up circuit, a DC motor, and a counter. The utility model is characterized in that the normally closed contact of a relay is controlled by the current which is formed after the voltage transformation and the rectification, and the closure of the normally closed contact is utilized to drive the DC motor to drive the counter to complete the stored count. The utility model with the advantages of simple structure and reliable counting can be used for three-phase motors as well as two-phase motors. The utility model is suitable for mobile power devices for time keeping and electricity timing.
Description
The utility model relates to a kind of electric power mobile device electricity consumption hour totalizer, belongs to the time set of electromechanical equipment.
The movability consumer in present rural area, as water pumper, rice thresher, log splitter etc., often be in the mobile operational process state, exist to tilt and generally measure ammeter, defectives such as waterproof and dustproof poor performance are so can't accurately calculate the power consumption of these mobile devices.Electric industry department and rural area electricity-management personnel feel inconvenience deeply for this reason, press for a kind of measuring apparatus that can adapt to electric power mobile device power consumption.
China's Patent Gazette for Utility Models discloses " electromechanical equipment working time accumulator " September 21 nineteen ninety, this accumulator links to each other the normally closed contact of relay respectively by lead with arbitrary grade of watch core battery of the quartz crystal of electronic watch, its main coil links to each other with the output terminal of rectifier; When electromechanical equipment was worked, electric current was by the output of transformer output terminal, through rectifier.Make the relay adhesive, point commonly used disconnects, and electronic watch picks up counting, and relay is normally closed closed, is stored between electronic watch clocks.
The defective of this device is to adopt the transformer step-down, and needs the electronics that timing is used to accumulative total to improve.
The purpose of this utility model provides a kind of electric power mobile device electricity consumption hour totalizer, wish its have simple in structure, timing is directly perceived, can be used for civilian electricity and can be used for power again.
This electric power mobile device electricity consumption hour totalizer comprises the transformation rectifier control circuit, start relay circuit and a direct current motor that cooperates with mechanical counter are formed, it is characterized in that: transforming circuit that described transformation rectification circuit is made up of the capacitor C 1 that is cascaded, C2 and resistance R 1 and the rectification circuit of D1～D4, C3 are formed, the output terminal of this transformation rectification circuit links to each other with the main line of a relay J ZC, and the relay normally closed contact links to each other by lead and through two contacts of a direct current power supply with a direct current motor 1; 1 in described direct current generator links to each other with a mechanical counter.
According to the electric power mobile device electricity consumption hour totalizer of above conceptual design, its advantage be simple in structure, timing is reliable, easy to make, with low cost.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: JZS is that relay, C1, C2, C3 are electric capacity, and 1 is direct current motor, and 2 is counter.
Below in conjunction with accompanying drawing, further describe the utility model.
Electric power mobile device electricity consumption hour totalizer described in the utility model, form reduction voltage circuit by capacitor C 1, C2, C3 and resistance R 1, be provided with three contacts in the circuit, wherein have two to cooperate so that insert the electricity consumption of 380V three phase electric machine, wherein two contacts cooperations then can insert the electricity consumption of 220V monophase machine in addition.Its output terminal of described rectification circuit links to each other with the main coil of relay J ZC, and the normally closed short of relay J ZC links to each other with two contacts of direct current motor respectively by lead, and string has the direct supply that drives direct current motor in the line simultaneously; 1 on described direct current motor is clamored with mechanical type counting and is linked to each other.In actual applications, described direct current motor 1 can serve as with the movement of quartz analog clock.
Through inventor's test of many times, hour totalizer is installed on the terminal box of equipment, as long as the energising of closing a floodgate is with regard to accurate timing.In utilization, need only equipment task time is multiplied by the power consumption that equipment rated power can calculate this mobile device.
