Embodiment
(embodiment 1)
Fig. 1 to Fig. 6 shows a kind of embodiment of the present invention, and wherein Fig. 1 is structural representation of the present invention; Fig. 2 is the concrete schematic diagram of Fig. 1 breaker in middle structure; Fig. 3 is circuit diagram of the present invention; Fig. 4 is the attainable range of regulation schematic diagram of single-phase voltage regulator; Fig. 5 is the attainable range of regulation schematic diagram of three-phase adjuster; Fig. 6 is that the switch back side of the present invention drives schematic diagram.
See Fig. 1 to Fig. 6, a kind of high accuracy distribution line adjuster, comprise governor body 1, regulating circuit plate is provided with in described governor body 1, described governor body 1 is provided with input terminal 2, lead-out terminal 3 summation current transformer 4 and voltage transformer 5, also be provided with construction of switch 6, the center of described construction of switch 6 is provided with the first reactor contact 7 and the second reactor contact 8, described construction of switch 6 is provided with and is the center of circle with the first reactance contact 7 and the contact 9 and nine gear switch contacts 10 at zero point becoming circular setting, and zero point contact 9 and each contact of nine gear switch contacts 10 include contact, left side and contact, right side, described first reactor contact 7 and the second reactor contact 8 are equipped with movable switch feeler lever 11, the outboard end activity of described movable switch feeler lever 11 touch zero point contact 9 or nine gear switch contacts 10 on, described construction of switch 6 is also provided with boosting and regulates contact 12 and reduction regulation contact 13, Zero-point switch contact 9 is provided with adjustment activity feeler lever 14, the activity of described adjustment activity feeler lever 14 is pressed on boosting and regulates on contact 12 or reduction regulation contact 13.
Described regulating circuit plate comprises input voltage, output voltage, common electric voltage, reactor and bridging coil, first contact of described first reactor contact and the second reactor contact and described reactor and the second contact is corresponding is connected, described output circuit is connected with described reactor, the boosting of described input voltage and described construction of switch regulates contact, reduction regulation contact is connected, described boosting regulates contact, reduction regulation contact is by contact or nine gear switch contacts and the first reactor contact at zero point, second reactor contact is connected, described bridging coil is connected between input voltage and common electric voltage.
Described input terminal, lead-out terminal are three-phase or single-phase terminal.
This switch is 9 gear switch, therefore time the first reactor contact a and the second reactor contact b overlaps, switch can adjust 9 grades, due to current limiting reactor can when certain electric current long-play, when a and b cross-over connection, not when same point, L can go to the half of step voltage, therefore after the upper reactor of string, progression can double, and becomes 18 grades.Switch has laid a boosting and step-down switching, and can change the polarity of series coil, same range of regulation can double, and therefore pressure regulation gear is 36 grades.
As shown in Figure 4, ± 11.25% range of regulation can be realized for single-phase voltage regulator.
As shown in Figure 5, on the basis of single-phase 10%, composition triangle connects, and three-phase regulator can realize ± 15% range of regulation.
As shown in Figure 6, Drive Structure is provided with at the back side of described governor body, described drive wire structure comprises the fluted disc 16 of band stator 15, being connected by energy-storaging spring 17 with bottom of described fluted disc 16, described construction of switch 6 connects gear 18 by gauge outfit and is connected with fluted disc 16, the center of described fluted disc 16 is provided with the rotating shaft of band moving contact 19 action, fluted disc rotates and moving contact 19 is abutted with stator 15 activity, be provided with between motor 20 with fluted disc 16 and coordinate dynamic tooth 21, controller 22 is connected with fluted disc by construction of switch.
Positive and negative conditioning function realizes, and rotates half-turn and realizes the function that contact rotates a circle, forward the positive and negative tune axle of time triggered of half-turn to, thus realize the action of switch (18)-N-(-18);
Extension spring rotor is fixed on gear wheel, gear wheel drives spring energy-storage, time to spring to peak, spring pulls gear wheel to release energy, and is fixed on the stator on gear wheel, drive instantaneously, the rotating shaft that contact action is rotated, realizes the action of switch, and gear indicates, be with electric limit function, ensure that controlling motor contact in+18 and-18 disconnects.
Structure of the present invention is simple, easy to use, effectively can improve stability and the range of regulation of adjustment, and compare the precision that conventional regulator it greatly improves pressure regulation, applicability is good, practical
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And these belong to connotation of the present invention the apparent change of extending out or variation still belong to protection scope of the present invention.
