Inquiry power supply, inquiry power supply scene be only provided with 1 road DC220V power supply, if will affect production after this 1 road power loss
The function of product causes failure and destruction to equipment；In general, scene is otherwise provided with 1 road AC220V power supply, but this is all the way
AC220V power supply, the product of not ready-made AC220V-DC220V on the market, and can not be formed with the 1 road DC220V at scene superfluous
It is remaining.
Summary of the invention:
The utility model is to provide a kind of redundant queries power supply to solve the above-mentioned problems of the prior art.
Technical solution used by the utility model has:
A kind of redundant queries power supply, the redundant queries plant-grid connection two-way power supply are all the way 220V AC power source, another
Road is 220V DC power supply, and the redundant queries power supply includes power-switching circuit, exchange warning circuit, redundant circuit and direct current
Warning circuit；
The input terminal of the power-switching circuit accesses 220V AC power source, and power-switching circuit switchs to AC power source directly
Redundant circuit is accessed after stream, exchange warning circuit is connected on power-switching circuit, when power-switching circuit generation is short-circuit or disconnected
Lu Shi, exchange warning circuit light the indicator light being connected on exchange warning circuit；
220V DC power supply is connected by direct current warning circuit with redundant circuit, when direct current warning circuit misconnection 220V is exchanged
When power supply, direct current warning circuit cuts off circuit, and lights the indicator light being connected on direct current warning circuit.
Further, the power-switching circuit is that AC220V turns DC220V circuit.
Further, the redundant queries power supply is arranged in a mounting shell, which is rectangular structure, is installing
Two are symmetrically arranged with mounting ear on outer wall in parallel to each other in shell, and mounting ear is L-square structure.
Further, it is set on the mounting shell there are two access interface and an output port, two access interface are distinguished
For connecting 220V AC power source and 220V DC power supply, output port is for connecting redundant circuit.
Further, the mounting shell is equipped with indicator light mounting hole.
The utility model has the following beneficial effects:
The utility model is realized scene AC220V and all the way DC220V inputs that ultimately form DC220V all the way defeated all the way
Product out, it is contemplated that a possibility that live wrong line, alarm control circuit is used, when detecting input power cord wrong
When, it can be automatically by this road dump of wrong, to electrical equipment not being interfered and be influenced.
Detailed description of the invention:
Fig. 1 is the utility model circuit diagram.
Fig. 2 is the utility model circuit theory frame.
Fig. 3 is the external mounting shell main view of the utility model.
Fig. 4 is the external mounting shell top view of the utility model.
Specific embodiment:
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figure 1 to Figure 4, a kind of redundant queries power supply of the utility model, redundant queries plant-grid connection two-way power supply, all the way for
220V AC power source, another way are 220V DC power supply, which includes power-switching circuit 1, exchange alarm electricity
Road 2, redundant circuit 3 and direct current warning circuit 4.
The input terminal of power-switching circuit 1 accesses 220V AC power source, and AC power source is switched to direct current by power-switching circuit 1
Afterwards access redundant circuit 3, exchange warning circuit 2 be connected on power-switching circuit 1, when power-switching circuit 1 occur short circuit or
When breaking (or component failure in power-switching circuit), exchange warning circuit 2, which is lighted, to be connected on exchange warning circuit
Indicator light.
220V DC power supply is connected by direct current warning circuit 4 with redundant circuit 3, as 4 misconnection 220V of direct current warning circuit
When AC power source, direct current warning circuit 4 cuts off the circuit of the 220V AC power source of misconnection, and lights and be connected to direct current warning circuit
On indicator light.
Power-switching circuit 1 is that AC220V turns DC220V circuit.
The utility model is arranged in a mounting shell 8 in redundant queries power supply, which is rectangular structure, is pacifying
Two are symmetrically arranged with mounting ear 81 on outer wall in parallel to each other in dress shell 8, and mounting ear 81 is L-square structure.It is set on mounting ear 81
There is connection through-hole.
It is set on mounting shell 8 there are two access interface and an output port, two access interface are respectively used to connect
220V AC power source and 220V DC power supply, output port is for connecting redundant circuit 3.Indicator light is equipped on stating mounting shell 8
Mounting hole.
The utility model uses the concatenated working principle of power module, with the mould that can easily purchase on the market
Block carrys out a group merging and realizes the product being relatively hard to buy on the market.Simultaneously as the cascaded structure used, than logical in outer dimension
Normal AC-DC module wants short, is more suitable for the blade type installation in cabinet, and the calorific value of integral product, power consumption are all compared
Single module greatly reinforces.Furthermore, it is contemplated that a possibility that live wrong line, uses alarm control circuit, when detecting
