A boats and ships emergency switching-off circuit, comprises relay K 1, relay K 2, relay K 3, circuit breaker shunt opening trip coil MX, emergency switching-off button SB1, resistance R 1, resistance R 2, break monitoring module Kx.The normally opened contact of described emergency switching-off button SB1 and resistance R 1 parallel connection, the circuit after parallel connection and resistance R 2 are connected into button box circuit 1, described button box circuit 1 connect with the coil of relay K 1 after circuit two termination AC220V control power supplys; The normally-closed contact of described relay K 1 is connected with the coil of relay K 2, the coils from parallel connection of coils of the circuit after series connection and described relay K 1; The L end of described break monitoring module Kx, N termination AC220V control power supply, and the signal input part L1 of described break monitoring module Kx is connected between described button box circuit 1 and relay K 1 coil; The normally opened contact series connection of described relay K 3 coils and relay K 2, after series connection, circuit two termination AC220V control power supply; The normally opened contact of described relay K 3 and circuit breaker shunt opening trip coil MX series connection, after series connection, circuit two termination AC220V control power supply.
Compared with prior art, the beneficial effects of the utility model are: native system is arranged on the main distribution board or other equipment of boats and ships, accurately and reliably continuous detecting emergency switching-off circuit opens circuit and short-circuit conditions, to fault, can realize Realtime Alerts, thereby avoid the generation of major accident, guarantee boats and ships and personal safety.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of boats and ships emergency switching-off circuit, comprises relay K 1, relay K 2, relay K 3, circuit breaker shunt opening trip coil MX, emergency switching-off button SB1, resistance R 1, resistance R 2, break monitoring module Kx.The normally opened contact of described emergency switching-off button SB1 and resistance R 1 parallel connection, the circuit after parallel connection and resistance R 2 are connected into button box circuit 1, described button box circuit 1 connect with the coil of relay K 1 after circuit two termination AC220V control power supplys; The normally-closed contact of described relay K 1 is connected with the coil of relay K 2, the coils from parallel connection of coils of the circuit after series connection and described relay K 1; The L end of described break monitoring module Kx, N termination AC220V control power supply, and the signal input part L1 of described break monitoring module Kx is connected between described button box circuit 1 and relay K 1 coil; The normally opened contact series connection of described relay K 3 coils and relay K 2, after series connection, circuit two termination AC220V control power supply; The normally opened contact of described relay K 3 and circuit breaker shunt opening trip coil MX series connection, after series connection, circuit two termination AC220V control power supply.
This circuit work power is AC 220V, and described break monitoring module Kx is used for the voltage signal of input to detect, and reports to the police according to the magnitude of voltage of setting.The operational voltage value that K1 relay detected as input L1 is less than 19V, and break monitoring module will be sent the break alarm on L1 road.Relay K 1 operating voltage of selecting is 220V (working limit scope 184～253V), and relay K 2 operating voltages of selecting are 120V(working limit scope 96～132V), relay K 3 operating voltages of selecting are 220V.Relay K 1 is for short circuit monitoring, and relay K 2 is carried out for emergency switching-off, and the possibility that is staggered and moved simultaneously by different operating voltages between two relays, to realize different purposes.
The resistance R 1 of described circuit 1, resistance R 2 are chosen suitable resistance after calculating, and make under normal circumstances, and when emergency switching-off button SB1 does not press, break monitoring module L1 end detects voltage about 29.35V left and right, relay K 1, and K2, K3 is failure to actuate.
When pressing emergency switching-off button SB1, the voltage at resistance R 2 two ends in emergency switching-off button box is about 130V left and right, break monitoring module L1 end detects voltage about 100V left and right, relay K 1 is failure to actuate, relay K 2 actions, relay K 3 is connected, and sends emergency switching-off instruction, corresponding circuit breaker disjunction on distribution panelboard.
When emergency switching-off button box is to the cable break between distribution panelboard, it is 0V that break monitoring module L1 end detects voltage, and break monitoring module Kx can send break alarm.
When short trouble appears in emergency switching-off button box, relay K 1 coil both end voltage is 220V, relay K 1 action, the control circuit of relay K 2 is disconnected by the normally closed auxiliary contact of K1, relay K 2 is failure to actuate, and relay K 3 is disconnected, and on distribution panelboard, corresponding circuit breaker can be by misoperation disjunction.In order to prevent that mistake from cutting off, move, this circuit relay electrical equipment K3 is mainly used in delay cutoff action.In circuit, can also send short-circuit alarming signal by other auxiliary contact of relay K 1, connect a short-circuit alarming device.Like this, Real-Time Monitoring cable burns and binds fault, and prevents mistake cut-out action circuit.
Described break monitoring module Kx is the equipment whether breaking for monitoring long distance line, there is disconnection monitoring and warning output function, when the actual use of boats and ships, break monitoring inside modules can arrange the even more monitoring, alarming circuits in 8 tunnels, to facilitate the emergency switching-off button box to being arranged on boats and ships everywhere to monitor in real time.
In addition to the implementation, the utility model can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
