Description
Technical field
The utility model belongs to power system compensation capacitor technical field, and in particular to a kind of anti-interference capacitor is answered
Close switching device.
Background technology
With developing rapidly for intelligent power network industry, Automation of Electric Systems has become focus of concern, changes
Make existing urban distribution network in national numerous cities to deploy, for intelligent grid, fling-cut switch turns into various controls
The basic means of system, the quality of fling-cut switch directly influences the respond of power network, while the quality of fling-cut equipment is also
Have influence on the interference that switching is brought to power network, current capacitor composite switching device has been widely used in the transformation of power network and new
In the erection construction of power network, in capacitor composite switching device, the process of capacitor actions plays vital effect, electricity
Container is as a kind of power component, and it, due to the characteristic of its relative short-circuit, can not only produce huge charging in the moment of connection
Electric current, while being also added to the circuit of switching with a variety of harmonic waves, therefore, suppression capacitor instantaneous peak current eliminates a large amount of
Disturb harmonic wave very necessary for improving capacitor composite switching device.
The content of the invention
The purpose of this utility model is, in order to overcome the deficiencies in the prior art, and to provide a kind of anti-interference capacitor and be combined
Switching device.
The utility model solves its technical problem and takes following technical scheme to realize：
A kind of anti-interference capacitor composite switching device, including the relay switch K1 and switched capacitor being connected in series
C1, and control relay switch the switch control unit of K1 open/close, it is characterised in that：In relay switch K1 and switching electricity
One in parallel of the series circuit two ends that container C1 is constituted are in series by relay switch K2, bypass resistance R1 and shunt capacitance C2
Resistance-capacitance type bypass circuit, relay switch K2 control end and lead to unit wink and be connected, lead to unit and switch control unit company wink
Connect, switch control unit Synchronization Control relay switch K1 and relay switch K2 open/close.
Moreover, the turn-on time for leading to unit the wink is the half of switched capacitor C1 charge cycle durations.
Advantage of the present utility model and good effect are：
1st, the utility model greatly reduces switched capacitor transient peak by increasing bypass circuit at capacitor two ends
Electric current, simultaneously.Bypass circuit curbs part interference harmonic wave.
2nd, the utility model is rational in infrastructure, realizes simply, will not bring big cost to the transformation of product, is adapted to city
Promote field.
Brief description of the drawings
Fig. 1 electrical block diagrams of the present utility model.
Embodiment
The utility model is implemented below in conjunction with accompanying drawing to be further described, following examples are descriptive, are not
Limited, it is impossible to protection domain of the present utility model is limited with this.
A kind of anti-interference capacitor composite switching device, as shown in figure 1, including the relay switch K1 that is connected in series and
Switched capacitor C1, and control relay switch the switch control unit of K1 open/close, and innovative point of the present utility model is,
One in parallel of the series circuit two ends that relay switch K1 and switched capacitor C1 is constituted are by relay switch K2, bypass resistance R1
And shunt capacitance C2 resistance-capacitance type bypass circuits in series, relay switch K2 control end and wink lead to unit and be connected, wink leads to
Unit is connected with switch control unit, switch control unit Synchronization Control relay switch K1 and relay switch K2 open/close.
In specific implementation of the present utility model, the turn-on time for leading to unit shown wink is switched capacitor C1 charge cycles
The half of duration, that is, switched capacitor C1 when just powering up resistance-capacitance type bypass circuit be also turned on, bypass circuit is to switching
Capacitor C1 produces bypass, suppresses interference harmonic wave, shares switched capacitor C1 instantaneous peak currents, when switched capacitor C1 chargings
When steadily reaching the half of capacity, lead to unit in wink and disconnect, resistance-capacitance type bypass circuit is cut off.
It is that effective reduction switched capacitor instantaneous peak current and suppression interference are humorous in specific implementation of the present utility model
Ripple, while be unlikely to the switching time of undue influence capacitor composite switching device again, when switched capacitor C1 is 400V,
During 30KVAR, the resistance of the bypass resistance R1 is between 30 ohm -60 ohm, and the value of the shunt capacitance C2 is switching electricity
The 1/20-1/50 of container C1 values.
