Description

Dual-power redundant power supply system of fire pump

Technical Field

The utility model relates to a fire-fighting equipment field is used in tire production, a redundant power supply system of fire pump dual supply is said in detail.

Background

As is well known, in the field of tire production, instantaneous high-power production equipment such as an internal mixer and a calender need to be used, and when a fault occurs, impact is easily formed on a power distribution system in a plant area, so that adverse consequences such as power grid fluctuation and switch tripping are caused. Due to the consideration of factors such as engineering economy, power distribution facilities such as a transformer cannot be independently configured for the fire pump, and when the generator is used as a standby power supply, when power supply and distribution faults (power failure, undervoltage, overvoltage, phase failure, frequency deviation and the like) occur, the standby power supply can be started and completed within 15 minutes, and the emergency starting requirement of the fire pump station cannot be met.

Disclosure of Invention

In order to overcome the not enough of prior art, the utility model provides a fire pump dual supply redundancy power supply system, furthest guarantees continuous, the steady operation of fire pump.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a fire pump dual supply redundant power supply system, be equipped with 1# power transformer, a characterized by, 1# power transformer draws forth a power cord and inserts dual supply unit common power upper end and corresponds binding post, draw forth a power cord by 2# power transformer and insert dual supply unit stand-by power supply upper end binding post, insert fire pump power cabinet circuit breaker upper end after common power supply lower extreme binding post connects in parallel with stand-by power supply lower extreme binding post, fire pump power cabinet circuit breaker lower extreme and 1# fire pump, 2# fire pump, 3# fire pump, 1# spray the pump, 2# spray the pump and 3# spray the circuit breaker upper end of pump and link to each other.

The beneficial effects of the utility model are that, when the power utilization breaks down suddenly or has a power failure, through dual power change over switch, on automatic input stand-by power supply, make equipment still can normal operating.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, a fire pump 1-1.1#, a fire pump 1-2.2#, a fire pump 1-3.3#, a spray pump 2-1.1#, a spray pump 2-2.2#, a spray pump 2-3.3#, a power transformer AA1025.1#, a power transformer AA1032.2#, a dual-power device A01, and a fire pump power cabinet breaker A02 are shown.

Detailed Description

In the figure, the utility model discloses draw forth a power cord by 1# power transformer AA1025 and insert newly-increased dual power supply device A01 common power supply upper end and correspond binding post, draw forth a power cord by 2# power transformer AA1032 and insert newly-increased dual power supply device A01 stand-by power supply upper end binding post, insert fire pump power cabinet circuit breaker A02 upper end after common power supply lower extreme binding post connects in parallel with stand-by power supply lower extreme binding post. The lower end of a fire pump power cabinet circuit breaker A02 is connected with the upper ends of water pump circuit breakers of a No. 1 fire pump 1-1, a No. 2 fire pump 1-2, a No. 3 fire pump 1-3, a No. 1 spray pump 2-1, a No. 2 spray pump 2-2 and a No. 3 spray pump 2-3, and finally control over 6 groups of pump stations is achieved.

The power supply can continuously supply power through the control of the dual-power microprocessor. When the common power fails or is in power failure, the power supply is automatically switched into the standby power supply through the dual-power-supply change-over switch, so that the equipment can still normally operate.
