Description
Technical field
The utility model relates to a kind of emergency protection circuit device for electric, the protective device of specifically a kind of reactive power compensation and filtering.
Background technology
In current power system, that is familiar with the quality of power supply along with the public gos deep into, and is also progressively deepening the cognition of reactive power compensation and filtering, meanwhile also correspond in the process of application and has occurred some problems.
In the aspect of Passively compensated and filtering, provide capacity current by capacitor, effect that the harmonic wave of the corresponding number of times of reactor filtering reaches compensation and filtering jointly, this wherein capacitor be the most impaired.For capacitor, the problem of overcurrent and overvoltage obtains effective control along with the progress of science and technology, and problem of temperature rise just becomes particularly evident, how to control temperature rise, becomes the problem of expert's special concern.But in the problem in the face of temperature rise, the protection controlling temperature rise device also just seems especially important.And under current techniques background, this part also belongs to clear area substantially.Equally, protective device also all haves much room for improvement targetedly.
Summary of the invention
The purpose of this utility model is to provide a kind of universal portable reactive power compensation protective device; failure protecting device is added in existing reactive power compensation and filter; because capacitor is obvious by the characteristic comparing of temperature limiting; so under the precondition ensureing each power cell air blast cooling; require that blower fan and controllable silicon start simultaneously, thus reduce heating original paper at power cell internal because of the impact produced of generating heat.Add temperature control element to controllable silicon, the inner each element of comprehensive guaranteed output unit runs, especially efficient, the long failure-free operation of capacitor.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: universal portable reactive power compensation protective device is made up of reactive power compensation and filtering base unit and failure protecting device, described reactive power compensation and filtering base unit, comprise the Capacitor banks be made up of capacitor; And the reactor corresponding with capacitors count; reactor accesses the A phase of power supply, B phase and C phase respectively; A, C two-phase circuit arranges controllable silicon; and the incoming end of power supply is provided with fling-cut switch; blower fan is serially connected with between A phase and C phase; described Capacitor banks, reactor, corresponding A, C two-phase controllable silicon and fling-cut switch form a loop; described failure protecting device comprises fuse and impacting type alarm, is serially connected between blower fan with A phase after described fuse and the parallel connection of impacting type alarm.
Described failure protecting device also comprises thermocouple, and described thermocouple is serially connected between controllable silicon and electronegative potential.
As preferably, in the main line of reactive power compensation and filtering base unit, anti-three-phase current unbalance formula breaker of plastic casing is installed.When circuit three characteristics of the middle term current imbalance or overcurrent time, breaker of plastic casing can carry out disjunction timely.
The beneficial effects of the utility model are: one, because capacitor is the whole power cell internal electric elements that To Be Protected from Heat, the existence of blower fan ensures that its temperature is within allowed band, disconnect as blower fan no longer rotates then impacting type alarm normally-closed contact because of fault, normally opened contact closes, provide fault-signal, and automatically exit, ensure the safe operation of equipment.
Two, when the position at complete equipment place affects fan radiating because current room temperature is overheated, the thermocouple being serially connected in controllable silicon side can automatically disconnect after reaching set point, makes this loop exit compensation, can provide fault-signal equally.
Three, anti-three-phase current unbalance formula breaker of plastic casing is installed in main line, when circuit three characteristics of the middle term current imbalance or overcurrent time, breaker of plastic casing all can carry out disjunction timely.Ensure the safe, reliable of the components and parts in loop, place.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Embodiment
As shown in Figure 1, universal portable reactive power compensation protective device is made up of reactive power compensation and filtering base unit and failure protecting device.
Described reactive power compensation and filtering base unit, comprise the Capacitor banks be made up of capacitor 21,22,23; And the reactor 31,32,33 corresponding with capacitors count, reactor 31,32,33 accesses the A phase 11 of power supply, B phase 12 and C phase 13 respectively, A, C two-phase circuit arranges controllable silicon 41,42, and the incoming end of power supply is provided with fling-cut switch 5, between A phase and C phase, be serially connected with blower fan 6, described Capacitor banks, reactor, corresponding A, C two-phase controllable silicon and fling-cut switch form a loop.
Described failure protecting device comprises fuse 7 and impacting type alarm 8, is serially connected between blower fan 6 with A phase after described fuse 7 and impacting type alarm 8 parallel connection.
Described failure protecting device also comprises thermocouple 9, and described thermocouple 9 is serially connected between controllable silicon and electronegative potential.
As preferably, in the main line of reactive power compensation and filtering base unit, anti-three-phase current unbalance formula breaker of plastic casing is installed.When circuit three characteristics of the middle term current imbalance or overcurrent time, breaker of plastic casing can carry out disjunction timely.
Operation principle is as follows: for controlling the temperature of power cell internal, namely guarantee that the real time temperature of compensation equipment position is within the scope of national standard, need install blower fan on each power cell casing top.The normal operation of the elements such as capacitor can be met, normal operating condition run indicator 102 Chang Liang through test of many times records blower fan in normal work.
If blower fan breaks down, the impacting type alarm 8 being connected in parallel on fuse 7 side will send alarm signal, makes whole power cell exit compensation.
And when silicon controlled temperature exceedes set point, the thermocouple 9 being serially connected in controllable silicon side will disconnect automatically, malfunction indicator lamp 103 sends information, with the safety of guaranteed output unit.
When three-phase current unbalance or occur other overcurrent, anti-three-phase current unbalance formula breaker of plastic casing disconnects automatically, and power supply indicator 101 cuts out, and this compensation circuit exits.Thus ensure that the safety of this power cell, reliably, for a long time run.
