Embodiment

As shown in Figure 1, economize on electricity alarm in workshop described in the utility model, comprise 220 volts of ac power supply terminal and its interior control circuit that are arranged on housing 1; Described control circuit comprises manual, automatic two position conversion switch SA; Described change over switch SA manually, the fixed contact of position is connected with hot terminal 2 automatically, the moving contact of described automatic position is connected with the inlet wire contact of sonic-opticalcon trolled switch K1, light-operated switch K2 respectively, the outlet contact of described sonic-opticalcon trolled switch K1 is connected with zero line binding post 3 by relay J, and the outlet contact of described light-operated switch K2 is connected with zero line binding post 3 by relay J A; The moving contact of described manual position is leaded up to relay K A and is connected with zero line binding post 3, and the normally-closed contact JA1 that relay J A is passed through on another road is connected with hot terminal sub 2; Be provided with workshop mains switch branch road, sound and light alarm branch road between hot terminal son 2 and zero line binding post 3; Described workshop mains switch props up the normally opened contact KA1 of route relay K A, the series circuit that the normally-closed contact FR1 that is series at the overcurrent protector FR in the supply line of workshop, A.C. contactor KM form, and at described A.C. contactor KM two ends, is parallel with electromagnetically operated valve YA; The parallel circuits that described sound and light alarm props up route loud speaker and lamp body composition forms, and normally opened contact J1 and the described parallel circuits of described relay J are in series.

The utility model operation principle is summarized as follows:

When change over switch SA being screwed into to automatic position state, (a point is connected, the b point disconnects) time, because have light in workshop daytime, so sonic-opticalcon trolled switch K1, light-operated switch K2 are all in closed condition, relay J A, J are in release condition, therefore no matter in workshop, sound is much, and the sound and light alarm branch road can not worked; Now, external power supply is through the normally-closed contact JA1 of relay J A engage relay KA coil, the normally opened contact KA1 closure of relay K A, and A.C. contactor KM coil obtains electric, its normally opened contact KM1 adhesive, power supply is powered to workshop through overcurrent protector FR.

When the evening draws on, light-operated switch K2 conducting, relay J A coil obtains electric its normally-closed contact JA1 and disconnects, A.C. contactor KM coil losing electricity, its normally opened contact KM1 disconnects the workshop dump.Now, sonic-opticalcon trolled switch K1, in the preparatory stage, is conducting as long as in workshop, sound of movement sonic-opticalcon trolled switch K1 is arranged, the relay J coil obtains electric its normally opened contact J1 closure, luminous and the sound that gives the alarm of sound and light alarm branch road work, to the robber its to the fright effect, and prompting is protected night personnel and is noted taking precautions against.

There is the portion gas pipeline valve not close to put in place to cause for fear of night and waste phenomenon, the electromagnetically operated valve YA in parallel at A.C. contactor KM coil two ends, due to night relay K A normally opened contact KA1 in off-state, so electromagnetically operated valve YA coil losing electricity, its valve core reset is by the gas pipeline valve closing.

When in workshop, power consumption equipment or supply line are short-circuited; the normally-closed contact FR1 that is series at the overcurrent protector FR in A.C. contactor KM coil circuit disconnects; A.C. contactor KM coil losing electricity, its normally opened contact KM1 disconnects and playing electricity consumption workshop overcurrent protection purpose.

If while running into workshop special circumstances palpus overtime work, as long as being screwed into to manual position state (the b point is connected, the disconnection of a point), change over switch SA gets final product.
