Abstract

The utility model provides a double carbon brushes compensating AC voltage stabilizer whose structure is composed of an annular autotransformer, a machine frame plate, a servo motor, carbon brushes, a carbon brush arm and a control circuit board for the servo motor, wherein, the control circuit board for the servo motor and the servo motor are installed on the machine frame plate, and the middle of the carbon brush arm is installed on the shaft end of the servo motor; the two carbon brushes are vertically installed on both ends of the carbon brush arm and are connected with the side of a winding on the annular autotransformer. The utility model can enable the autotransformer to maintain stable output of voltage and electric current during the time of higher and lower voltage output, so the utility model has the advantages of simple structure, small size, low cost, stable performance, reliable work, etc.

Description

Two carbon brush compensation type ac voltage stabilizers

The utility model relates to a kind of converting equipment, specifically a kind of pair of carbon brush compensation type ac voltage stabilizer.

Along with the continuous increase of household electrical appliance and business automation equipment with popularize, people propose more and more higher requirement to the stability of supply voltage, have the unit and the individual of high-grade household electrical appliance and personal computer for those, for the safety that guarantees equipment runs well and works and all will set up stabilized voltage supply, but with regard to all kinds of stabilized voltage supplys of being sold in the market, all kinds of stabilized voltage supplys of prior art mainly contain transformer gear shift offset-type, department's clothes Electric Machine Control self-coupling type and department's clothes Electric Machine Control self-coupling add transformer offset-type three major types, wherein the deficiency that in use exists of transformer gear shift offset-type is: a grade conversion is arranged, gear is limited, input voltage is beated greatly, the precision degree is low, output power when the high-end and low side of input voltage descends significantly, the more important thing is because the buty shifting of relay causes output moment dead electricity easily, this is to home appliance, and especially household PC equipment can cause bigger influence.The deficiency that second class department clothes Electric Machine Control self-coupling type in use exists is: output power descends along with the decline of voltage, and when input voltage dropped to 160V, output power only was equivalent to 50% of nameplate output rating.The 3rd class department clothes Electric Machine Control self-coupling adds the transformer offset-type in use with the moment dead electricity and the problem that descends of output power that can overcome preceding two kinds of stabilized voltage supplys, but still have because of use two transformers to make cost increase, volume increase the problem that energy consumption also increases thereupon.

The purpose of this utility model provide a kind of simple in structure, cost is low, volume is little, have department clothes Electric Machine Control automatic coupling voltage regulator and transformer and compensate bifunctional single automatic coupling voltage regulator, two carbon brush compensation type ac voltage stabilizer.

The purpose of this utility model realizes in the following manner, and three windings of coiling on the iron core of annular automatic coupling voltage regulator adopt two carbon brush double winding side slip to compensate mutually and carry out voltage output and set up the tertiary winding aiming at department's clothes circuit for controlling motor power supply.

Accompanying drawing 1 is the structural representation of two carbon brush compensation type ac voltage stabilizers.

Accompanying drawing 2 is the input and output wiring schematic diagram of two carbon brush compensation type ac voltage stabilizers.

With reference to Figure of description to of the present utility model pair of carbon brush compensating-type AC voltage stabilization Device explains below doing.

Of the present utility model pair of carbon brush compensating ac. voltage stabilizer, its structure is by annular self-coupling device [6], frame plate [3], department takes motor [2], carbon brush [5] [7], carbon brush arm [4] and department take circuit for controlling motor plate [1] and form, department takes circuit for controlling motor plate [1] and department takes motor [2] and is installed on the frame plate [3], the centre of carbon brush arm [4] is installed in department and takes the axle head of motor [2], two carbon brush [5] [7] be vertically mounted on carbon brush arm [4] two ends and and annular self-coupling device [6] on winding L₁、L ₂Side Face contacts.

Annular automatic coupling voltage regulator [6] is by iron core B, winding L ₁, L ₂, L ₃Form winding L ₁End and civil power zero line b, voltage table V and voltage output end B and connect, carbon brush [7] is as armature contact and winding L ₁Join, and and winding L ₂Centre tap join and meet the live wire a of civil power through the contact of switch K W and fuse BX, carbon brush [5] is as armature contact and winding L ₂Join, and through contact Z and the voltage output end A of the contact switch J of relay and voltage table V, switch K and connect winding L ₃Join with department's clothes circuit for controlling motor on the department clothes circuit for controlling motor plates [1] and to be its power supply.

Embodiment:

The processing and fabricating of the two carbon brush compensation type ac voltage stabilizers of the utility model is very simple and convenient, installs shown in the by specification accompanying drawing to make to get final product.The course of work of this pair carbon brush compensation type ac voltage stabilizer is as follows: civil power enters the winding L of annular automatic coupling voltage regulator from live wire a and zero line b ₁, L ₂, carbon brush [5] [7] slides on two windings, and when line voltage reduced, carbon brush [5] was to winding L ₁High-pressure side slide, carbon brush [7] is equally in winding L ₂Go up to high-pressure side and slide with the compensation winding L ₁Because of increasing the voltage drop that umber of turn produced.Also be same conversely, when line voltage raise, carbon brush [5] was to winding L ₁Low pressure end slide, carbon brush [7] is equally in winding L ₂Go up to low pressure end and slide to reduce winding L ₁The voltage that is induced on iron core is to get stable electric current and voltage output.Two the contact W of switch K and Z be used for respectively controlling voltage output end A and B and pressure regulator join or directly and civil power join; relay in the contact switch J department clothes circuit for controlling motor of relay is controlled; shield, department's clothes circuit for controlling motor is a prior art.

Of the present utility model pair of carbon brush compensating ac. voltage stabilizer is compared with existing technology, Can make pressure regulator when higher or lower voltage input, keep stable voltage and electricity The output of stream, i.e. stable power stage, thereby have simple in structure, volume is little, The characteristics such as cost is low, stable performance, reliable operation have well and promote the use of Be worth.

Except the described technology feature of specification, be those skilled in the art Know technology.
