摘要:
The device for regulated water heating using the energy gained by photovoltaic cells, which consists of terminals (X1, X2, X3, X4, X5), where to the terminal (X1) is brought a protective earth (PE), which is then brought to a thermostat (T2), whereas to the terminal (X2) is brought a line conductor (L) of the alternating current, which is then brought to a normally closed contact (Y1) of a thermal fuse (TP) and then the line conductor (L) is brought to a normally closed contact of a thermostat (T2) and then the line conductor (L) is brought to a terminal (A1) of a coil of the contactor (ST), whereas to the terminal (X3) is brought a neutral conductor (N), which is then brought to a normally closed contact (Y2) of the thermal fuse (TP) and than the neutral conductor (N) is connected to a terminal (A2) of the coil of the contactor (ST), whereas to the terminal (X5) is brought a conductor (L+) of the direct current, which is than brought to a terminal (1) of a switch of the contactor (ST) and than the conductor (L+) is brought from a terminal (6) of a switch of the contactor (ST) to an inlet terminal of a heating coil (R2), whereas to the terminal (X5) is brought a conductor (L-) of the direct current, which is then brought to a second inlet terminal of the heating coil (R2).

摘要:
Power switching equipment for boilers used within regulated water heating using direct current from photovoltaic panels consists of two contactors (ST1, ST2), a thermal fuse (TP), thermostat (T), heating elements (R), two signal devices (S1, S2) and wiring terminals (X1, X2, X3, X4, X5, X6, X7). The equipment uses both direct (DC) as well as alternating (AC) current. The positive pole of the direct current power source (DC) is directed to the main terminals of both contactors (ST1, ST2). Contactor coils are used to switch the direct current (DC) between contactors (ST1, ST2); these coils are powered by alternating current (AC) which passes through the thermostat (T) and the thermal fuse (TP) before reaching the coils.
