A host employs a modular integration technology, is connected with an emergency power supply main body by use of the plug-ins and can be directly drawn out from the emergency power supply main body, the operation is simple, and the convenience and the practicality are high.

Description

A kind of small-power host module fire-fighting emergency power supply

Technical field

The present invention relates to fire-fighting emergency power supply technical field, specifically relate to a kind of small-power host module fire-fighting emergency power supply.

Background technology

As a kind of stand-by power supply, emergency power supply has now been widely used in the places such as subway, market, hospital, government affair centre, skyscraper.Simultaneously as a kind of fire-fighting electronic product, the safety problem of emergency power supply self also becomes more and more important, and people also more and more pay attention to for the safety of emergency power supply.

In actual applications, emergency power supply is installed in the small spaces such as electric well, power distribution station more, and heat-dissipating space is not enough, and running time is long, easily causes Yin Wendu too high and breaks down; When fault occurs, be difficult to maintenance because of narrow space.As fire product, can not safeguard by on-call maintenance, when there is fire-fighting accident, can not come into operation in time, time serious, can extreme loss be caused.

Summary of the invention

For the technical problem existed in prior art, the object of the present invention is to provide a kind of small-power host module fire-fighting emergency power supply, when breaking down, do not need field service, only need change host module, and operation is extremely simple, convenient and practical.

To achieve these goals, the technical solution adopted in the present invention is:

A kind of small-power host module fire-fighting emergency power supply, host module is installed in cabinet by plug-in installation, host module be placed in the storage battery of cabinet, transformer and distribution section and be connected respectively by plug part;

Host module includes input circuit breaker Q FA, charger input circuit breaker Q FC, charger LKC, inverter ZPT, contactor KM1, contactor KM2 and exports circuit breaker Q F;

When civil power is normal, exports circuit breaker Q F and go to power output end, civil power is through input circuit breaker Q FA and contactor KM1 directly to load supplying, and civil power is powered to charger LKC by charger input circuit breaker Q FC, and charger LKC is to storage battery power supply;

When mains-supplied is interrupted or line voltage transfinites, contactor KM1 disconnects, and the direct current energy of storage battery is reverse into AC energy by inverter ZPT, then powers to output through transformer;

When line voltage recovers normal, by synchronous grid-connected handoff technique, closed contactor KM1, realizing powers from inversion forwards mains-supplied to;

When the power fails, output circuit breaker Q F is gone to bypass output, and civil power is directly to load supplying.

Small-power host module fire-fighting emergency power supply of the present invention, its beneficial effect shows:

1, make emergency power supply unit installation, convenient disassembly a lot, efficiently solve the problem of maintenance difficult when fault occurs.

2, the reliabilty and availability of system can be improved, improve the intelligence degree of emergency power supply.

The inner space of 3, emergency power supply have also been obtained very large optimization, save and very large utilize space.

4, main frame adopts modularization integrated technique, adopts plug part to be connected with emergency power supply main body, can directly extract out from emergency power supply main body, simple to operate, convenient and practical.

Accompanying drawing explanation

Fig. 1 is the cabinet outline drawing of fire-fighting emergency power supply.

Fig. 2 is the structural representation of host module.

Fig. 3 is the electrical schematic diagram of emergency power supply.

Embodiment

For further describing the present invention, below in conjunction with drawings and Examples, the present invention is described in further detail, but within the scope of embodiments therefore do not limited the present invention to.

Refer to Fig. 1 and 2, a kind of small-power host module fire-fighting emergency power supply, comprise cabinet 2, host module 1 is installed in cabinet 2 by plug-in installation, host module 1 be placed in the storage battery 3 of cabinet 2, transformer 5 and distribution section 5 and be connected respectively by plug part.

See also Fig. 3, host module 1 includes input circuit breaker Q FA, charger input circuit breaker Q FC, charger LKC, inverter ZPT, contactor KM1, contactor KM2 and exports circuit breaker Q F.

When civil power is normal, export circuit breaker Q F and go to power output end, civil power is through inputting circuit breaker Q FA and contactor KM1 directly to load supplying, power supply carries out city's electro-detection and charge in batteries management, inverter ZPT does not work, the power supply of the now actual use of user load is the civil power from electrical network, and therefore inverter ZPT is in resting state when civil power is normal always, can effectively reach energy-conservation effect.Civil power is powered to charger LKC by charger input circuit breaker Q FC, and charger LKC is to storage battery power supply.

When mains-supplied is interrupted or line voltage transfinites, emergency power supply disconnects contactor KM1 at once, operated inverter ZPT, the direct current energy of storage battery is reverse into AC energy, power to output through transformer again, now, the power supply that user load uses is the AC power changed by the inverter of emergency power supply, instead of from civil power.

When line voltage recovers normal, the control system of emergency power supply detect civil power normal after, by synchronous grid-connected handoff technique, closed contactor KM1, realizing powers from inversion forwards mains-supplied to, and now, inverter ZPT enters resting state.After this, civil power powers to the load through contactor KM1 by emergency power supply.

When the power fails, output circuit breaker Q F is gone to bypass output, and civil power is directly to load supplying.

Above content is only to design example of the present invention and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
