Abstract

An electric power standby equipment energy saving device is provided, and a power switch is externally connected on a total power circuit of the standby electric power equipment; an output terminal of a starting switch of the standby electric power equipment is an input terminal of a voltage comparater, and the other input terminal of the voltage comparater is a standard voltage value input terminal; an output terminal of the voltage comparater is connected with a base electrode of a triode, a collector electrode of the triode is connected with a relay, and a normal open contact point of the relay is arranged on the total power circuit of the standby electric power equipment. The technical scheme is employed, an original circuit is added with simple components, power consumption of the electric power standby equipment is effectively reduced, electric energy is greatly saved, and national grid energy saving requirement is obtained.

Description

Electric power standby device energy conservation device
Technical field
This patent relates to the aid of power domain, relates to specifically a kind of energy saver.
Background technology
Power equipment work off and on is a lot.When not needing power equipment work, these power equipments often are in holding state, and standby must consume electric energy, does not meet the energy-conservation requirement of national grid.
Summary of the invention
The purpose of this utility model is to provide a kind of effectively energy-conservation electric power standby device energy conservation device.
For achieving the above object, the utility model is by the following technical solutions:
A kind of electric power standby device energy conservation device, an external power switch on the general supply circuit of stand-by electric equipment; With the output terminal of the starting switch of a stand-by electric equipment input terminal as voltage comparator, another input terminal of voltage comparator is the standard voltage value input end; The base stage of the lead-out terminal connecting triode of voltage comparator, the collector connection relay of triode, relay normally open contact are arranged on the general supply circuit of stand-by electric equipment.
The starting switch of stand-by electric equipment is the remote sensing switch.
Adopt the utility model of technique scheme, increased simple components and parts on original circuit base, just can effectively reduce the power consumption that electric power is treated machine equipment, thereby greatly save electric energy, meet the energy-conservation requirement of national grid.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
As shown in Figure 1, a kind of electric power standby device energy conservation device, an external power switch K1 on the general supply circuit of stand-by electric equipment; In general, the power equipment of standby has a starting switch K2, and this starting switch K2 can be remote sensing switch etc.With the output terminal of the starting switch K2 of a stand-by electric equipment input terminal as voltage comparator U, another input terminal of voltage comparator is the standard voltage value input end; The base stage of the lead-out terminal connecting triode Q of voltage comparator U, the collector connection relay J of triode Q, relay normally open contact J-1 are arranged on the general supply circuit of stand-by electric equipment.
Principle of work of the present utility model is: in the utility model, and the monostable circuit that voltage comparator U consists of.When power switch K1 and starting switch K2 pressed, voltage comparator U exported high level, drove triode Q conducting, made relay J work, and its normally opened contact J-1 enters closure state.At this moment, supply socket is connected, the power equipment normal operation.
When power equipment shut down, starting switch K2 disconnected, by the monostable circuit output low level that voltage comparator U consists of, and not conducting of triode Q, the relay J dead electricity, its normally opened contact J-1 disconnects.At this moment, the supply socket outage, thus electric power is treated that the power consumption of machine equipment reduces greatly.

Claims (2)
