Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Illustrate, to facilitate related personnel to better understand the technical solution.
As shown in figures 1 and 3, the external signal interaction mechanism of static reactive generator, including installation shell 1 are pressed in one kind,
It installs and static reactive generator 4 is set inside shell 1, install and offer mounting hole on shell 1, there is aviation plug 2 in mounting hole
It passes through, the one end of aviation plug 2 inside installation shell 1 is connect with static reactive generator 4.
Static reactive generator 4, by detection module, control computing module and compensation three basic function modules of output module
It constitutes, its working principle is that then going out current electric current via control chip analysis by the current information of external CT detection system
Information, such as PF, S, Q；Then the driving signal of compensation is provided by controller, is finally made of power electronic circuit.capacitor inverse
It becomes road again and issues compensation electric current, static reactive generator is electric from commutation bridge-type using that can turn off power electronic devices (IGBT) composition
Road is connected in parallel on power grid by reactor, suitably adjusts the amplitude and phase of bridge circuit exchange side output voltage, Huo Zhezhi
It connects and controls its ac-side current.Reactive power needed for absorbing or issue rapidly, realizes the idle purpose of quick dynamic regulation,
As active type compensation device, the dash current of impingement load can be not only tracked, but also harmonic current can also be carried out
Tracing compensation, static reactive generator 4 can be influenced in the process of work by electromagnetic wave, so in order to guarantee that static reacance is sent out
The normal work of raw device 4, we must assure that around static reactive generator 4 without electromagnetic wave, and static reactive generator 4 is set
Set installation shell 1 inside, the transmitting of electromagnetic wave mainly passes through conducting wire and hole slot, now will installation shell 1 be designed to it is closed,
Not with external contact, mounting hole is opened up on installation shell 1, aviation plug 1 is passed through from mounting hole, and one end of aviation plug 2 exists
The inside of shell 1 is installed, one end is arranged between aviation plug 2 and installation shell 1 and is electromagnetically shielded in the outside of installation shell 1
Filler fills up gap, ensure that the absolute closing of installation shell 1, therefore electromagnetic wave will not enter installation by hole slot
In shell 1, and aviation plug 2 can block propagation of the electromagnetic signal by conducting wire, so can not also enter peace by conducting wire
Inside casing 1, the normal work of static reactive generator 4 ensure that.
As shown in Figure 1-3, offering maintenance window 5 on installation shell 1, maintenance cover board 3, dimension are covered on maintenance window 5
It builds and is provided with electromagnetic shielding liner between plate 3 and installation shell 1, installation shell 1 is provided in the side for opening up maintenance window 5
First tapped blind hole 6, maintenance cover board 3 are fixed by screws on installation shell 1.
Maintenance window 5 is opened up on installation shell 1, it is convenient that static reactive generator 4 is overhauled, in the process of work
In, maintenance window 5 is covered by maintenance cover board 3, can guarantee the closing for installing shell 1 in this way, installs and the first spiral shell is arranged on shell 1
Then line blind hole 6 will be repaired cover board 3 by screw and is mounted on installation shell 1, blind hole is the blind hole for through-hole
It is to connect surface layer and internal layer without the via hole of perforation, due to not penetrating through, so electromagnetic signal will not enter installation from hole
Inside shell 1, when in use, maintenance cover board 3 is covered on maintenance window 5, although being fixed by screw, dimension
Building inevitably will appear gap between plate 3 and installation shell 1, if be not pocessed, electromagnetic signal can enter peace from gap
Inside casing 1, and then the normal work of static reactive generator 4 is influenced, is arranged between installation shell 1 and maintenance cover board 3
Electromagnetic shielding liner can be filled gap, and electromagnetic shielding liner is usually made of microporous materials, such as polyurethane
Foams can not only shield electromagnetic signal but also elasticity with higher, so having preferable sealing effect, ensure that quiet
The only airtightness of 4 working environment of reacance generator.
As shown in figures 1 and 3, the second tapped blind hole is provided with around mounting hole, aviation plug 2 is fixed by screws in peace
On casing 1, aviation plug 2 and installation 1 bracket of shell are provided with electromagnetic shielding filler.
Aviation plug 2 can prevent electromagnetic signal from entering inside installation shell 1 by conducting wire, and aviation plug 2 passes through peace
It fills hole and in order to guarantee the fixation of aviation plug 2 second tapped blind hole is set around mounting hole, by screw by aviation
Plug 2 is fixed on installation shell 1, but inevitably will appear gap in mounting hole, in order to guarantee sealing effect, in gap
Filling electromagnetic shielding filler, ensure that the closure of 4 working environment of static reactive generator.
The external signal interaction mechanism of static reactive generator, specifically used process are as follows: send out static reacance are pressed in one kind
The inside of installation shell 1 is arranged in raw device 4, and aviation plug 2 is installed in mounting hole, fixed by screw and installation shell 1,
The filling electromagnetic shielding filler at gap, the one end and static reactive generator 4 of aviation plug 2 inside installation shell 1 connect
It connects, external one end is connect with outer lead, then maintenance cover board 3 is covered on maintenance window 5, in maintenance cover board 3 and peace
Electromagnetic shielding liner is set between casing 1, and installation shell 1 is at closed state, when needing to static reactive generator 4 and boat
When blind plug 2 is overhauled, maintenance cover board 3 is removed, is then overhauled by maintenance window 5.
The external signal interaction mechanism of static reactive generator is pressed in one kind, the setting of static reactive generator 4 is outer in installation
Inside shell 1, and maintenance window 5 is set on installation shell 1, maintenance window 5 is covered by maintenance cover board 3 when in use, peace
Aviation plug 2 is also set up on casing 1, in the inside of installation shell 1, one end is outer installation shell 1 for one end of aviation plug 2
Portion, the gap between aviation plug 2 and installation shell 1 is filled by electromagnetic shielding filler, so static reactive generator 4 is in work
Not with external contact when work, and aviation plug 2 can block transmitting of the electromagnetic signal in conducting wire, avoid electromagnetism letter
Number by conducting wire be transmitted to installation shell 1 inside, this external signal interaction mechanism and traditional external signal interaction mechanism phase
Than possessed advantage are as follows: shielded to electromagnetic signal, ensure that the normal work of static reactive generator 4, mechanism
Setting rationally, facilitates maintenance.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as the improvement for the various unsubstantialities that the conception and technical scheme for using the utility model carry out,
Or it is not improved the conception and technical scheme of the utility model are directly applied into other occasions, in the guarantor of the utility model
Within the scope of shield.
