Description

No cabinet power supply module based on intelligent object

[technical field]

The utility model is applicable to the power-supply system of station with power moduleization, and lay special stress on cancellation tradition station power cabinet is realized the modular combination of station with power supply.

[background technology]

At present, traditional transformer station is made up of two kinds of structures usually with the low-voltage alternating current power supply cabinet, and a kind of is to be assembled by rack, disconnecting link, circuit breaker, current transformer, voltmeter, ammeter, universal seclector, indicator light, connection bus; Another kind is assembled by rack, switch with knifeshaped fuse, contactor, auxiliary relay, the time relay, current transformer, voltmeter, ammeter, universal seclector, indicator light, connection bus.Transformer station's station low-voltage alternating current power supply cabinet of above-mentioned two kinds of structures, because the disconnecting link or the switch with knifeshaped fuse that are adopted can't be realized automatic conversion, contacts of contactor shake, heating, oxidation, cling, therefore can not realize the two lockings of mechanical electric, two-way power supply " collision " fault takes place easily, and relay circuit complexity, failure rate height, poor reliability, automaticity are low, can not realize telecommunication, can't satisfy the requirement of comprehensive automation system of transformer substation.

And existing intelligent transformer station is made up of rack, automatic change-over, two circuit breakers, Programmable Logic Controller, display operation module, electric quantity monitoring module, voltage monitoring module, auxiliary relay and universal seclectors with the low-voltage alternating current power supply cabinet, the transformer station of this structure low-voltage alternating current power supply cabinet, though possessed basic intelligent requirement, but because the distribution of internal structure electrical equipment is not compact, structure is scattered, and reliability is not high; The circuit complex distribution of intermodule is not easy to maintenance and assembling like this.

[summary of the invention]

At the problem of above-mentioned existence, the purpose of this utility model provides a kind of internal standard layout, intermodule does not have cable and connects, assembles the station intelligent modularized structure of power supply flexibly.

In order to achieve the above object, the utility model comprises based on the no cabinet power supply module of intelligent object: switchgear module, sensor assembly and intelligent monitoring device module are integrated in the cabinet, secondary connection does not go out cabinet, and casing externally has only communication interface to be connected with the integrated monitoring device that is exclusively used in transformer station's power supply.

Described integrated monitoring device connection can be connected realization with inlet wire module of interchange, feeder line module of interchange, interchange secondary inlet wire module, interchange secondary feeder line module, charging module, step-down module, inverter module, communication power supply module, the dc feeder module that contains the detection of insulating and storage battery detection module and monitor.

Described module connects by guide pin bushing or connection rail all around.

Connect by at least four dividing potential drop guide pillars between about the described module.

But described dividing potential drop guide pillar is a connect-disconnect structure.

Advantage of the present utility model is:

1. owing to realize each function, can be configured targetedly according to different needs like this by the connection between the module;

2. connect owing to utilizing guide pin bushing between the module or connecting rail, thereby can be standard assemblied, clear in structure, easy to assembly, simple, thus increase work efficiency;

3. Stability Analysis of Structures, repair and maintenance is very convenient;

4. thermal effect is low, reduces element damage, and product useful life is provided;

5. light, be fit to carrying;

6. the internal module splicing structure protects, has strong anti-impact force.

[description of drawings]

Fig. 1 is the schematic diagram of the utility model based on the no cabinet power supply module of intelligent object.

Fig. 2 is that the utility model is based on the connection diagram between the module of the no cabinet power supply module of intelligent object.

[embodiment]

Just the utility model is described in further detail below in conjunction with accompanying drawing and enforcement:

As shown in Figure 1: the utility model is integrated in the cabinet 10 by switchgear module 11, sensor assembly 12 and intelligent monitoring device module 13 based on the no cabinet power supply module of intelligent object, secondary connection does not go out cabinet, and casing 10 externally has only communication interface 14 to be connected with the integrated monitoring device 15 that is exclusively used in transformer station's power supply.

Described integrated monitoring device 15 can be connected with inlet wire module 151 of interchange, feeder line module 152 of interchange, interchange secondary inlet wire module 153, interchange secondary feeder line module 154, charging module 155, step-down module 156, logical variable power source module 157, communication module 158, the dc feeder module 159 that contains the detection of insulating and storage battery detection module 160 to be monitored.

As shown in Figure 2: described module 21 and module 22 connect by guide pin bushing or connection rail 31 all around, perhaps take mechanism to connect, and guarantee that its connection reliability can make it easy to connect, quick, stable.

Pressure appears piling up for fear of each module layer poststack, and the rational fixation problem in stacked back, described module 21 and module connect by four dividing potential drop guide pillars 32 between about in the of 22, and its effect is to play interconnect function up and down, also plays the effect of bearing, sharing gravity.

Stack the inconvenient situation of back appearance maintenance in order to solve each module layer simultaneously, situations such as the inconvenient activity of module, but described dividing potential drop guide pillar 32 is set to connect-disconnect structure.

Like this, arbitrarily dismounting between each module, easily change, make things convenient for internal overhaul and do not influence its structural stability, outside no any fixedly vestige.

Advantage of the present utility model is:

1. owing to realize each function, can be configured targetedly according to different demands like this by the connection between the module;

3. Stability Analysis of Structures, repair and maintenance is very convenient;

4. thermal effect is low, reduces element damage, prolongs product useful life;

5. light, be fit to carrying;

6. the internal module splicing structure protects, has stronger anti-impact force.

The above person is the utility model most preferred embodiment only, is not to be used to limit scope of the present utility model, and all equivalences of being done according to the utility model claim change or modify, and are all the utility model and contain.
