Twin coil safety relay (such as the more morals of DOLD electrical UG8851 product), there are two coil, a title SET for tool Coil, another is known as RESET coil.
In the control of SET coil, the normally opened contact of relay is stayed open, and normally-closed contact keeps normally closed, and RESET coil When control, normally opened contact closure, and normally-closed contact is opened.By setting act priority be arranged when two coils operate simultaneously after The state of appliance contact.SET coil is such as set with high priority, then when two coil simultaneously operations, normally opened contact holding is beaten It opens, normally-closed contact remains closed;And when RESET is set with high priority, normally opened contact is then closed, and normally-closed contact is opened.
This twin coil safety relay uses pulse control, i.e., the pulse of application certain time is in SET and RESET line Circle after the actuating of relay, disconnects control circuit, and the state of relay can unanimously be kept.When two coils do not control, relay Device keeps the last one to control pulse controlled state.
This twin coil safety relay has the contact of single-pole double throw or the combination of normally opened+normally-closed contact.Wherein, if it is double Coil safety relay is the relay of single-pole double throw, then common point is connected to railway switch control signal, controls goat, such as schemes Shown in 3.If twin coil safety relay is the combination of normally opened+normally-closed contact, connection relationship is as shown in Figure 4.
The process that the control system of A system and B system composition carries out the switching of two systems is as follows:
(1) assume that A system controls relay, so that A system railway switch control signal becomes effective railway switch control signal, control Goat processed;
(2) the RESET coil priority with higher that setting B system connects;
(3) A system breaks down, and not can control, and information is uploaded to control host;
(4) host transmitting order to lower levels controls goat by B system;
(5) B system issues RESET coil control command, and the normally-closed contact of relay is disconnected, normally opened contact closure;
(6) B system railway switch control signal becomes effective railway switch control signal control goat.
During B system turnover control circuit control goat, if necessary to safeguard A system, then directly by the correlation of A system Hardware board is extracted, and is changed to the intact board of function, during safeguarding to A system, B system controls always goat, track Traffic operation does not interrupt.
