Problems solved by technology

[0015] Therefore, when the voltage between the contacts of the contact portion S2 of the second mechanical contact switch 13 contains a noise component when the second mechanical contact switch 13 is turned on, the load 3 bidirectionally communicates with the triac. Unintended on or off of switch S3 synchronously malfunctions
In this case, as a result, there is a problem that the operation reliability of the hybrid relay 1 is unstable

[0032] A hybrid relay according to a first embodiment of the present invention will be described with reference to the drawings. figure 1 It is a schematic circuit diagram showing the circuit configuration of the hybrid relay 1 of the first embodiment.

[0033] 1. Structure of Hybrid Relay 1

[0034] Such as figure 1As shown, the hybrid relay 1 of the first embodiment forms a closed circuit together with the AC power source 2 and the load 3 by connecting the AC power source 2 and the load 3 connected in series. That is, the power supply and power supply cutoff from the AC power supply 2 to the load 3 are performed according to the ON state and the OFF state of the hybrid relay 1 . The AC power supply 2 is, for example, a 100V commercial power supply or the like. The load 3 is, for example, a lighting fixture including a fluorescent lamp or an incandescent lamp, or a ventilation fan.

[0035] Hybrid relay 1 has: terminal 10, which is connected to the other end of AC powe...

Abstract

Provided is a hybrid relay provided with a first mechanical contact switch, the contact point of which is opened and closed by a first drive unit, a second mechanical contact switch, the contact point of which is opened and closed by a second drive unit that is separate from the first drive unit, a semiconductor switch that is serially connected with the second mechanical contact switch, said hybrid relay being characterized in that the first mechanical contact switch and the series circuit constituted by the second mechanical contact switch and the semiconductor switch are connected in parallel, and a snubber circuit is connected in parallel to the first mechanical contact switch, on a feedline that supplies power to a load from a power source.

Description

technical field [0001] The invention relates to a hybrid relay equipped with a mechanical contact switch and a semiconductor switch. Background technique [0002] Conventionally, in order to switch power supply and cutoff to a load having an inverter circuit for inverter control such as lighting fixtures, a hybrid relay including a mechanical contact switch and a semiconductor switch connected in parallel has been used. A load having an inverter circuit is provided with a large-capacity smoothing capacitor for converting an AC voltage into a DC voltage. When the load is powered on from the AC power supply, a large current flows into the smoothing capacitor, and a surge current flows into the load. Especially in the case of a high load such as a high power supply voltage, since the inrush current flowing into the load increases, a large current based on the inrush current also flows in the hybrid relay connected between the load and the AC power supply. [0003] Therefore, ...
