Description
Technical field
Switching control device when the utility model relates to a kind of low-voltage power electric network reactive compensation and makes Power Capacitors refers in particular to a kind of dynamic and intelligent combination switch.
Background technology
Carried out the element of low-pressure reactive compensation power capacitor switching task, the normal operation A.C. contactor in the past.When using the alternating electromagnetic contactor, owing to shoving in the moment generation of capacitor break-make, the contact of contactor is easily burnt out; During capacitor put into operation, itself not only had power consumption the electromagnetic contactor coil, and the possibility of also burning because of heating is very big, so useful life is short, poor stability.
The utility model content
The purpose of this utility model is to provide a kind of dynamic and intelligent combination switch, and it has solved the problem that above-mentioned alternating electromagnetic contactor exists, and is not only safe but also reliable.
For achieving the above object, the solution that the utility model is taked is:
A kind of dynamic and intelligent combination switch, comprise by microprocessor, the control of controllable silicon, relay and relay form, the control of described microprocessor and controllable silicon, relay is installed on the dynamic and intelligent composite switch circuit plate, the control connection microprocessor of described controllable silicon, relay, described relay is arranged on the combination switch terminals.
Described dynamic and intelligent combination switch is in parallel with magnetic latching relay and have an operating passing zero function.
Described dynamic and intelligent combination switch and three-phase alternating voltage circuit output end series reactor and harmonic filter.
Described dynamic and intelligent combination switch and capacitor loops are installed discharge indicating lamp, and described indicator light is installed on the capacitor terminal.
Beneficial effect with respect to prior art is:
1, include microprocessor, the Based Intelligent Control capacitor switches.
2, with controllable silicon power on/off container group, without electric arc, no-flashy-flow, response is fast.
3, the conducting internal resistance is very little, does not produce harmonic wave, does not produce inrush phenomenon.
4, operating passing zero: the basic functional principle of combination switch is with the control of controllable silicon, relay and magnetic latching relay and connects, realize that voltage zero-cross conducting and current over-zero disconnect, make combination switch have advantages of the control no-flashy-flow of controllable silicon, relay in the moment that switches on and off, and during normal the connection, have advantages of the physical switch idle.Its implementation is: during input in the conducting of voltage zero-cross moment control controllable silicon elder generation, stable after again with magnetic latching relay adhesive conducting; And when excision is first magnetic latching relay to be disconnected, and the controllable silicon delay zero-crossing disconnects, thereby realizes the zero passage excision.
5, antijamming capability is strong.

Embodiment
Below in conjunction with accompanying drawing intelligent compound switch provided by the utility model is carried out step explanation:
As depicted in figs. 1 and 2, this dynamic and intelligent intelligent compound switch, comprise by microprocessor, the control of controllable silicon, relay and relay form, the control of described microprocessor and controllable silicon, relay is installed on the dynamic and intelligent composite switch circuit plate, the control connection microprocessor of described controllable silicon, relay, described relay are arranged on dynamic and intelligent combination switch terminals.
Described intelligent compound switch is in parallel with magnetic latching relay and have an operating passing zero function.
Described intelligent compound switch and three-phase alternating voltage circuit output end series reactor and harmonic filter.
Described intelligent compound switch and capacitor loops are installed discharge indicating lamp, and described indicator light is installed on the capacitor terminal.
This dynamic and intelligent combination switch uses and can finish desirable no-power compensation function with dynamic type (output of 12V direct current) controller, and the calculating of compensation arrangement total capacity is identical with the calculating of general static compensating device total capacity.
Mend altogether the capacitor of dynamic and intelligent combination switch control, adopt the capacitor of three-phase delta connection, rated voltage is 0.4kV, and control signal is one, simultaneously conducting A, B, C three-phase; Divide the capacitor of mending the control of dynamic and intelligent combination switch, adopt the capacitor of three-phase Y connection, rated voltage is 0.23kV, and control signal is three, difference conducting A, B, C three-phase.
The main electrical scheme terminal of dynamic and intelligent combination switch requires the connection of wire must use the OT terminal stud.
Dynamic and intelligent combination switch main circuit connects conductor cross-section and all selects by 1.5 times of specified phase current.
It is that our company is according to a kind of dynamic and intelligent combination switch that can carry out to shunt capacitor switching of low-voltage reactive compensator capable exploitation that described dynamic and intelligent is replied combination switch by cable, it has absorbed the thyristor no-voltage and has dropped into, zero current excision and contactor conducting internal resistance are little, athermic advantage, having overcome the defectives such as the caused electric arc that shoves of contactless contactor switched capacitor, is that the optimal NEW TYPE OF COMPOSITE of city and countryside power grid modification engineering switched capacitor is opened the light.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection range of the utility model claims.
