Abstract
The utility model relates to a device for realizing redundant power. The device comprises a first path of power, a second path of power and a relay with eight terminals. The first path of power A, the second path of power B and an output end are connected with two terminals of the relay respectively. The other two of the eight terminals are connected with a relay coil, and are also connected in parallel with the two paths of power respectively. The two terminals connected with the output end are connected with the terminals connected with the first and second paths of power through an armature. The shortcoming of unreliability caused by single-path power supply to a system is effectively overcome, and the device is simple and convenient to operate, so that a distributed control system (DCS) can be used stably.
Description
Technical field
The utility model relates to a kind of device of realizing redundant power.
Background technology
DCS, i.e. so-called dcs, or be referred to as distributing system in some data is a kind of novel computer control system for Centralized Control System, it is in the development of the basis of Centralized Control System, develops and come.Aspect systemic-function, the difference of DCS and Centralized Control System is little, but considers that at the DCS system power supply all is redundant power, and is namely but fully different on the implementation method of systemic-function.Duplex feeding can be avoided the single service unreliability that operation brings to system like this, and the favourable Systems balanth that computerizeds control uses.But in the SUPCON DCS system in early days, computer power supply is not but considered to adopt redundant, makes a big impact so just for operation and explained hereafter.
Summary of the invention
For addressing the above problem, the utility model adopts following technical scheme:
A kind of device of realizing redundant power is characterized in that comprising one road power supply, two road power supplys and relay D with terminal.
One road power supply, two road power supplys and output terminal circuit link to each other with two terminals of relay D respectively, and other has two terminals to be connected with relay coil, and the terminal that is connected with relay coil is connected in parallel with the two-way power supply respectively again.
Two terminals that are connected with output terminal and with terminal that one road power supply, two road power supplys are connected between connect by armature.
One road power supply is respectively equipped with switch with being connected on road power supply and the circuit that terminal is connected.
The output terminal circuit links to each other with equipment such as computing machines.
This utility model has effectively overcome the unreliability that single service brings to system, and equipment is simple, and is easy to operate, makes the use that the DCS system can be stable, solved the large problem in operation and the explained hereafter.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of relay of the device of realizing redundant power.
Wherein A is one road power supply, and B is two road power supplys, and C connects computing machine, and D is relay, Isosorbide-5-Nitrae, and 5,8,9,12,13,14 are relay terminal.
Embodiment
As shown in Figure 1, a kind of device of realizing redundant power comprises one road power supply, two road power supplys, with the relay of coil.One road power supply is succeeded electrical equipment 1,4 terminals; Two road power supplys are succeeded electrical equipment 5,8 ends give, simultaneously two road power supply cut-in relays 13,14 terminals (coil); Like this when the two-way power supply send electricity simultaneously, because relay coil gets electric, relay contacts (1,9), (4,12) terminal disconnects, terminal (5,9), (8,12) adhesive, so power supply is through K2, be connected into relay by relay 5,8 terminals, because (5,9), (8,12) adhesive is so power supply is by 9,12 terminals output 220VAC.If at this moment one the tunnel has a power failure, on the impact of relay output power supply nothing, if two road power supplys have a power failure, the relay coil outage, get an electric shock (5,9), (8,12) disconnect, (1,9), (4,12) adhesive, power supply is through K1, be connected into relay by relay 1,4 terminals, because (1,9), (4,12) adhesive is so power supply is by 9,12 terminals output 220VAC.So namely realized the redundancy of power supply, and saved cost, consumptive material is as long as a 220VAC relay.
Through repetition test repeatedly, on not impact of output power supply.Realized the control of supervisory control comuter power supply redundancy.Thereby ensured the normal operation of device.
This redundant power design can also be used for the 24VDC Power supply.But should note selecting the relay model, 220VAC and 24VDC can not use with relay.
