Abstract
The invention discloses a power-saving overload start and interruption relay. The relay is characterized in that little power is consumed when the relay is used in a normal state; the power-saving overload start and interruption relay is designed by using a conductive plate contact, a thermodynamic metal plate and a logic voltage comparison detector unit as main components; the relay is manually pressed down or carried, the conductive plate contact or a movable plate is buckled by a latch, a power supply is conducted or the movable plate or the conductive plate is separated from the buckle to release an on-off power supply; when power is supplied to the relay for use, if a lead short-circuit voltage declines to a set point, the logic voltage comparison detector unit immediately conducts the voltage of a voltage storage capacitor to start an electromagnetic device to generate magnetic lines, so that a push shaft of the electromagnetic device quickly pushes the clamping hook conductive plate to start or interrupt the power supply; and if overload happens when power is supplied to the relay for use, the clamping hook is separated from the conductive plate contact by using the bending property of the thermodynamic metal plate to start or interrupt the power supply or the thermodynamic metal plate is bent and the conductive contact is separated.
Description
Technical field
The present invention relates to a kind of relay, particularly a kind of power saving overload breaks relay.
Background technology
At present, the use of electric power is very general because supply of electric power has very large convenience, therefore, electric product all with electric power as power source, in the society, the popularity of electric power has become one of important indicator of weighing national economic development.
But in electricity consumption or power supply simultaneously easily; also dangerous property; in order to reduce the danger in electricity consumption or the power supply; by fuse is set in circuit; in order to product and the safety guarantee current supply line in the protection power supply, make circuit in the situation that current supply line short circuit or undesired overload occur, fuse is automatic disconnection immediately; can prevent from causing contingency, as electric wire cock off, product burns.
Existing history for many years for electrical fuses; according to the demand on using; common fuse type has the types such as fusing type, no-fuse switch; all types of fuses in use respectively have pluses and minuses; for example fusing type fuse needs to change, though the no-fuse switch fuse need not change, when protection; the time that fuse disconnects is longer, and present electricity consumption power supply all required fuse all require the convenience of shorter opening time, use and higher cost performance.
Summary of the invention
For the problems referred to above, the invention provides a kind of power saving overload and break relay.
The invention provides a kind of power saving overload and break the relay invention, its feature is used not power consumption of relay in normality, it is that a kind of power saving overload of being designed to of main element combination breaks relay that this relay is provided with conducting strip contact and the moving sheet metal of heat and logic voltage comparison detector unit, this relay uses manually to press or to move and fastens conducting strip contact or activity template by tenon and make turn-on power or move and make activity template or conducting strip tenon break away to be released to breaking power supply, when in the relay power supply is used, occur the wire short-circuit voltage drop to set point by logic voltage comparison detector unit immediately the voltage starting electromagnetic device of conducting voltage reservior capacitor produce the magnetic line of force and make the electromagnetic device impeller-hub push fast the grab conducting strip open breaking power supply, power supply is used the generation overburden to move sheet metal flexural property grab disengaging conducting strip contact by heat and is broken power supply or the disengaging of the moving sheet metal bending of heat conductive junction point such as relay, this logic voltage comparison detector unit starts the electromagnetic device impeller-hub immediately to be pushed grab open and breaks power supply, so can save long-time electric power and the manufacturing cost that consumes of relay electromagnetic device, can prevent again the cock off generation of event of power supply short circuit wire, ensure the safety of using product.
Embodiment
The invention provides a kind of power saving overload and break the relay invention, its feature is used not power consumption of relay in normality, it is that a kind of power saving overload of being designed to of main element combination breaks relay that this relay is provided with conducting strip contact and the moving sheet metal of heat and logic voltage comparison detector unit, this relay uses manually to press or to move and fastens conducting strip contact or activity template by tenon and make turn-on power or move and make activity template or conducting strip tenon break away to be released to breaking power supply, when in the relay power supply is used, occur the wire short-circuit voltage drop to set point by logic voltage comparison detector unit immediately the voltage starting electromagnetic device of conducting voltage reservior capacitor produce the magnetic line of force and make the electromagnetic device impeller-hub push fast the grab conducting strip open breaking power supply, power supply is used the generation overburden to move sheet metal flexural property grab disengaging conducting strip contact by heat and is broken power supply or the disengaging of the moving sheet metal bending of heat conductive junction point such as relay, this logic voltage comparison detector unit starts the electromagnetic device impeller-hub immediately to be pushed grab open and breaks power supply, so can save long-time electric power and the manufacturing cost that consumes of relay electromagnetic device, can prevent again the cock off generation of event of power supply short circuit wire, ensure the safety of using product.
