Abstract
The utility model provides a noel dual-supply automatic change-over switch which comprises a common power supply port, a standby power supply port, an output port and a housing mechanism. The common power supply port, the standby power supply port and the output port are all disposed on the housing mechanism. The common power supply port is connected with a main power supply input end through a signal line. The standby power supply port is connected with a standby power supply input end through a signal line. The main power supply input end, the standby power supply input end and the signal lines are all disposed in the housing. A structure of direct connection of copper bars of the dual-supply automatic change-over switch can be formed because the power supplies and the lines are disposed in the housing, only line ports are disposed externally, and copper bars preset at the ports can be directly connected with a constant power supply line, a standby power supply line and an output power supply line. Therefore, instability of the lines caused by manual operation is prevented. Furthermore, since external ports allow easy installation, the novel dual-supply automatic change-over switch is thus elegant in appearance, more convenient for detachment and replacement, and further satisfies the characteristic of stable power supply safety lines of a dual-supply circuit breaker.
Description
Technical field
The utility model relates to field of electrical equipment, is specifically related to a kind of novel duplicate-power automatic change-over.
Background technology
Double power supply automatic transfer switch is widely used in factories and miness or the unit of a type load and two type loads.The mode of operation of double power supply automatic transfer switch is, when conventional power supply closes a floodgate in situation about disconnecting, to access immediately stand-by power supply, thereby realize uninterrupted power supply demand.Under the background of using double power supply automatic transfer switch so in enormous quantities, people are not merely to consider from practicality, fail safe to the demand of double power supply automatic transfer switch, and also can be to the complexity of the mounting means of double power supply automatic transfer switch on the basis of these standards, overhaul the aspects such as the convenience degree of changing or even the aesthetic measure of double power supply automatic transfer switch self and select.The copper bar of existing double power supply automatic transfer switch is because need have bolted point, and connecting copper bar needs the punching of in-site measurement dimensioned, and difficulty is very large, also not attractive in appearance.Especially rectification module mode is only upgraded in employing, must adopt copper bar to connect, and wherein also involves the dismounting of original copper bar, and difficulty is larger.
Utility model content
The technical problem that the utility model solves is to provide a kind of novel duplicate-power automatic change-over, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of novel duplicate-power automatic change-over is provided, comprises conventional power port 1, stand-by power supply port 2, output port 4 and casing mechanism 3; Described conventional power port 1, stand-by power supply port 2, output port 4 are all arranged on casing mechanism 3, described conventional power port 1 is connected with main power source input by holding wire, described stand-by power supply port 2 is connected with stand-by power supply input by holding wire, and wherein main power source input, stand-by power supply input, holding wire are all arranged in casing mechanism.Described output port is arranged on duplicate supply casing mechanism one side
Described conventional power port is arranged on a left side of face of casing mechanism.
Described stand-by power supply port is arranged on a right side of face of casing mechanism.
Described shell mechanism consists of dielectric resin material.
Described output port is taked the inner direct-connected mode of copper bar.
Beneficial effect
The beneficial effects of the utility model are: due to power supply and circuit built-in, line port is only stayed in outside, and can directly connect normal stand-by power supply circuit and out-put supply circuit at the default copper bar of port, and then can form the direct-connected structure of double power supply automatic transfer switch copper bar, so the circuit causing while exempting because of manual operation is unstable, and the external easy installation of port, more elegant in appearance, also more convenient for overhauling replacing, further meet the stable feature of double-power supply breaker power supply safety circuit.
Accompanying drawing explanation
Fig. 1 is a kind of novel duplicate-power automatic change-over structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As Fig. 1, conventional power port 1, stand-by power supply port 2, casing mechanism 3, output 4.
A kind of novel duplicate-power automatic change-over, comprises conventional power port 1, stand-by power supply port 2, output port 4 and casing mechanism 3; Described conventional power port 1, stand-by power supply port 2, output port 4 are all arranged on casing mechanism 3, described conventional power port 1 is connected with main power source input by holding wire, described stand-by power supply port 2 is connected with stand-by power supply input by holding wire, and wherein main power source input, stand-by power supply input, holding wire are all arranged in casing mechanism.
Described output port 4 is arranged on duplicate supply casing mechanism 3 one sides
Described conventional power port 1 is arranged on a left side of face of casing mechanism 3.
Described stand-by power supply port 2 is arranged on a right side of face of casing mechanism 3.
Described shell mechanism 3 consists of dielectric resin material.
Described output port 4 is taked the inner direct-connected mode of copper bar.
Due to power supply and circuit built-in, line port is only stayed in outside, and can directly connect normal stand-by power supply circuit and out-put supply circuit at the default copper bar of port, and then can form the direct-connected structure of double power supply automatic transfer switch copper bar, so the circuit causing while exempting because of manual operation is unstable, and the external easy installation of port, more elegant in appearance, also more convenient for overhauling replacing, further meet the stable feature of double-power supply breaker power supply safety circuit.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model, the technical staff of the industry should understand, the utility model is not restricted to the described embodiments, that in above-described embodiment and specification, describes just illustrates principle of the present utility model, do not departing under the prerequisite of the utility model spirit and scope, the utility model also has various changes and modifications, these changes and improvements all fall within the scope of claimed the utility model, the claimed scope of the utility model is defined by appending claims and equivalent thereof.
