Description
本发明涉及用户变压器设备技术领域,具体涉及一种宽范围多档可调节可升降压的用户变压器。The invention relates to the technical field of user transformer equipment, in particular to a user transformer with wide-range and multi-step adjustable and adjustable voltage and voltage.
电力是以电能作为动力的能源,发明于19世纪70年代。电力的发明和应用掀起了第二次工业化高潮,现在人们的日常生活以及社会的发展均离不开电力,作为生产与输送电力给用户的电力企业,由于其服务的用户量大,每个用户的用电量都不恒定,以及局部性的电力消耗量变化,电力公司常常需要对低压配网电力的输送进行不断调控,比如一段时间内对台区配电变压器低压三相负荷进行不平衡调整,来最大程度保证不同相的用户的电力供应,让用户获得的电压均能在电器可以正常使用的合格范围内。而在实际情况下,总会存在一些台区三相负荷随机变化,各种因素均会导致三相负荷不平衡情况发生,对于越来越依赖电能的我们来说,电压波动所带来的影响也越来越大,对电器的损耗也极其明显,同时输入电压与电器的额定电压相差很大时,也会导致电器不能使用或损耗高甚至损坏。Electricity is an energy source that uses electrical energy as power and was invented in the 1870s. The invention and application of electric power set off the second climax of industrialization. Nowadays, people's daily life and social development are inseparable from electric power. As an electric power enterprise that produces and transmits electric power to users, due to the large number of users it serves, each user The power consumption is not constant, and the local power consumption changes, the power company often needs to continuously control the transmission of low-voltage distribution network power, such as unbalanced adjustment of the low-voltage three-phase load of the distribution transformer in Taiwan for a period of time. , to ensure the power supply of users of different phases to the greatest extent, so that the voltage obtained by the user can be within the qualified range for normal use of electrical appliances. In practice, there will always be some random changes in the three-phase load in the station area, and various factors will cause the three-phase load to be unbalanced. For us who are more and more dependent on electric energy, the impact of voltage fluctuations It is also getting bigger and bigger, and the loss to the electrical appliance is also extremely obvious. At the same time, when the input voltage is very different from the rated voltage of the electrical appliance, it will also cause the electrical appliance to be unusable or the loss is high or even damaged.
现有的方式是采用稳压器对电压进行微调,但是稳压器对电压的调节范围有限,调节的范围较窄,当输入的电压与额定电压相差±50%,便会出现过载使用,容易过载烧毁,而且稳压器一般由调压回路、控 制电路及伺服电机等组成,稳压器本身耗能、能源转换效率低。The existing method is to use a voltage stabilizer to fine-tune the voltage, but the voltage adjustment range of the voltage stabilizer is limited, and the adjustment range is narrow. Overload burns, and the voltage stabilizer is generally composed of a voltage regulation circuit, a control circuit and a servo motor. The voltage stabilizer itself consumes energy and has low energy conversion efficiency.
因此对一些台区低压三相电压极不稳定的区域来说,针对不同的输入电压,仍然能够以同样的额定输出电压输出,同时转换范围宽、能源转换效率高,更加方便实用。Therefore, for some regions where the low-voltage three-phase voltage is extremely unstable, for different input voltages, the output can still be output at the same rated output voltage, and at the same time, the conversion range is wide and the energy conversion efficiency is high, which is more convenient and practical.
为此,我们提出一种宽范围多档可调节可升降压的用户变压器。To this end, we propose a user transformer with wide range and multi-stage adjustable buck-boost.

所述防护机壳1上设置有两个电压输入接头5,且防护机壳1上设置有两个电压输出接头7,其中一个电压输入接头5与换相开关相互连接,另一个铜丝接头引出线4.5连接与其中一个电压输出接头7相互连接,电压输出接头7的两端分别与两个铜丝引出输出接头相互连接。The protective housing 1 is provided with two voltage input connectors 5, and the protective housing 1 is provided with two voltage output connectors 7, of which one voltage input connector 5 is connected to the commutation switch, and the other copper wire connector leads out.

根据变压器的原理,在一个闭合的铁芯上绕两个或以上的线圈,当一个线圈通入交流电源时(就是初级线圈),线圈中流过交变电流, 这个交变电流在铁芯中产生交变磁场,交变主磁通在初级线圈中产生自身感应电动势,同时另外一个线圈(就是次级线圈)中感应互感电动势。通过改变初、次级的线圈匝数比的关系来改变初、次级线圈端电压,实现电压的变换,此时通过设置多个不同匝数比铜丝接头4.3,继而能够实现对多个不同的电压的进行调节,但是此时多个不同匝数比铜丝接头4.3是采用一一对应的方式与换相开关2进行连接的,因此由于铜丝匝数的不同,其处理的电压范围也不同,可以调节较低范围以及较高范围的电压。According to the principle of the transformer, two or more coils are wound on a closed iron core. When one coil is connected to the AC power supply (that is, the primary coil), an alternating current flows through the coil, and this alternating current is generated in the iron core. In the alternating magnetic field, the alternating main magnetic flux generates its own induced electromotive force in the primary coil, and at the same time, the other coil (that is, the secondary coil) induces a mutual inductive electromotive force. By changing the relationship between the primary and secondary coil turns ratio to change the primary and secondary coil terminal voltage, to achieve voltage conversion, at this time by setting a number of different turns ratio copper wire joints 4.3, and then can achieve a number of different However, at this time, multiple copper wire connectors 4.3 with different turns ratios are connected to the commutation switch 2 in a one-to-one correspondence. Therefore, due to the difference in the number of copper wire turns, the processing voltage range is also Differently, the lower range as well as the higher range voltage can be adjusted.
换相开关2采用LW26型号换相开关,该型号换相开关2具有6个档位,且6个档位分别对应多个不同匝数比铜丝接头4.3,当确认输入的电压后,通过转动换相开关2上的旋钮,确定出相应的匝数比铜丝,使得该匝数比的铜丝能够处理的电压范围与输入的电压相接近,将输入的电压转化为额定电压,同时能源的转换效率高,耗能较低。The commutation switch 2 adopts the LW26 type commutation switch. This type of commutation switch 2 has 6 gears, and the 6 gears correspond to a number of different turns ratio copper wire joints 4.3. After confirming the input voltage, by turning The knob on the commutation switch 2 determines the copper wire with the corresponding turns ratio, so that the voltage range that the copper wire with this turns ratio can handle is close to the input voltage, and the input voltage is converted into the rated voltage. High conversion efficiency and low energy consumption.
