Abstract
The utility model relates to a signal lamp with an electric relay, composed of an electric relay J, a light-emitting element L, a triggering signal switch K and a normally closed button switch FA, wherein, one end of the electric relay J is connected to a contact 2, and the other end is connected iwth the kathode of a power supply through the light-emitting element L. A normally open contact switch JK1 and the normally closed button switch FA of the electric relay, which are connected in series, are connected in parallel with the trigger signal switch K, and then are connected between the anode of the power supply and the contact 2. when the trigger signal switch K is closed under particular cases, the electric relay can be electrified to work, the normally open contact switch JK1 can be closed to play a self-maintenance role for the power supply, and the light-emitting element L can emit light continuously.
Description
The utility model relates to a kind of signal lamp, is meant that especially the main transformer oil mass is too high in the unattended duty electric substation, the signal lamp of light gas action.
Existing signal lamp generally is to be controlled by switch or remote control switch, and its most outstanding shortcoming is to realize the self protective function of delaying time, and also be difficult for realizing multiple spot control, and volume is excessive.
The purpose of this utility model is to provide a kind of signal lamp of the self protective function of can realizing delaying time, and volume is little, and is convenient to realize remote multiple spot control.
For achieving the above object, the technical scheme that the utility model adopted is, design a kind of signal lamp of tape relay, this lamp is made up of relay J, light-emitting component L, triggering signal K switch and normally closed push button switch FA, wherein one of relay J terminate on the contact 2, the other end is connected with power cathode by light-emitting component L.The normally opened contact switch JK1 of relay J and normally closed push button switch FA series connection back are in parallel with the triggering signal K switch, are connected between positive source and the contact 2.When the triggering signal K switch was closed under specific circumstances, relay J got electric work.Normally opened contact switch JK1 closure plays power supply self-sustaining effect, and light-emitting component L continues luminous.When needing to recover, can press normally closed push button switch FA, make the relay J outage, JK1 transfers normally open to, and light-emitting component L extinguishes.
In the technical scheme described in the utility model, can increase a plurality of relay contact switch as required easily, to realize control to the multiple spot remote motion signal.
Advantage applies of the present utility model can realize the self-insurance of delaying time at its compact conformation, and can realize multiple spot control easily.
Below in conjunction with drawings and Examples architectural feature of the present utility model is further described.
Fig. 1 the utility model circuit theory diagrams.
The J-relay
L, L1-light-emitting component
K-triggering signal switch
The FA-normally closed push button switch
JK1-normally opened contact switch JK2, one group of transfer contact switch of JK3-wherein JK2 are the normally opened contact switch, and JK3 is the normally-closed contact switch
Present embodiment provides a kind of signal lamp of tape relay, shown in Fig. 1 the utility model circuit theory diagrams, this lamp includes relay J, light-emitting component L, L1, triggering signal K switch and normally closed push button switch FA and normally opened contact switch JK1, wherein one of relay J terminate on the contact 2, be provided with two groups of light-emitting components in this routine described scheme, can be electrooptic cell and multiple combination of elements such as bulb, light-emitting diode specifically, light-emitting component L1 be connected in parallel on the light-emitting component L1.The other end of described relay J is connected with power cathode by light-emitting diode L, L1 respectively, can show at the multi-faceted signal that carries out.The normally opened contact switch JK1 of relay J and normally closed push button switch FA series connection back are in parallel with the triggering signal K switch, are connected between positive source and the contact 2.When the triggering signal K switch was closed under specific circumstances, relay J got electric work.Normally opened contact switch JK1 closure can play the self-sustaining effect of power supply, and it is luminous that light-emitting diode L and L1 are continued.When needs recover, can press push-button switch FA and make the relay J outage, normally opened contact switch JK1 promptly transfers normally open again to.At this moment, light-emitting diode L and L1 extinguish.Relay J in the present embodiment also includes normally opened contact switch JK2 and normally-closed contact switch JK3, can arbitrarily connect multiple spot remote motion signal control device according to site specific.
