Abstract
The utility model discloses a wireless composite switch. The wireless composite switch comprises a silicon controlled switch, a circuit detection device, a microprocessor, a wireless transmitting and receiving module and a breaker, wherein the silicon controlled switch is connected with the circuit detection device, the circuit detection device and the wireless transmitting and receiving module are connected with the microprocessor, the wireless transmitting and receiving module is provided with a wireless monitoring system, the wireless monitoring system further comprises an acquisition module, a transmission module and a data processing module, the acquisition module and the data processing module are connected through the transmission module, and the breaker is arranged at a wire connection end of the composite switch. According to a scheme, the wireless composite switch has advantages of zero-voltage switching and zero-current removal of a thyristor, small internal conduction resistance of a contactor and no heating, and a disadvantage of surge arc generation is settled, the surge arc generation occurs when a contactor switch performs switching on a capacitor.
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 wireless 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 shove in the moment generation of capacitor break-make, the contact of contactor is burnt out easily; 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 wireless 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 wireless combination switch, comprise reverse-blocking tetrode thyristor, circuit checker, microprocessor, wireless transmission receiver module, circuit breaker, described reverse-blocking tetrode thyristor connecting circuit checkout gear, described circuit checker is connected microprocessor with the wireless transmission receiver module, described wireless transmission receiver module arranges a wireless monitor system, described wireless monitor system further comprises acquisition module, transport module, data processing module, by the transport module radio communication, described circuit breaker is arranged on the combination switch terminals between acquisition module and the data processing module.
The described wireless combination switch harmonic filter of connecting with the three-phase alternating voltage circuit output end.
Described wireless 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 reverse-blocking tetrode thyristor and magnetic latching relay and connects, realize that voltage zero-cross conducting and current over-zero disconnect, make combination switch have the advantage of reverse-blocking tetrode thyristor no-flashy-flow in the moment that switches on and off, and during normal the connection, have the advantage of 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.
Description of drawings
Fig. 1 is structure principle chart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing wireless combination switch provided by the utility model is carried out step explanation:
As shown in Figure 1, this wireless combination switch, comprise reverse-blocking tetrode thyristor, circuit checker, microprocessor, the wireless transmission receiver module, circuit breaker, described reverse-blocking tetrode thyristor connecting circuit checkout gear, described circuit checker is connected microprocessor with the wireless transmission receiver module, described wireless transmission receiver module arranges a wireless monitor system, described wireless monitor system further comprises acquisition module, transport module, data processing module, by the transport module radio communication, described circuit breaker is arranged on the combination switch terminals between acquisition module and the data processing module.
The described wireless combination switch harmonic filter of connecting with the three-phase alternating voltage circuit output end.
Described wireless combination switch and capacitor loops are installed discharge indicating lamp, and described indicator light is installed on the capacitor terminal.
Described wireless combination switch is that our company is according to a kind of combination switch that can carry out to shunt capacitor switching of low-voltage reactive compensator capable exploitation, 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.
