Description

где: V-вектор напр жени ; /-ток; Z и Z -сопротивление, пропорциональные сов гиперболы (фиг. 2). рассто ни м от фоку№ 96329- 2 -where: V-vector voltage; /-current; Z and Z -resistance proportional to owl hyperbola (Fig. 2). distance from focus # 96329-2 -

Z --сопротивление, пропорциональное рассто нию между ветв ми г 1Г1ерболы.Z is the resistivity proportional to the distance between the branches of the rG1bola.

Условием работы устройства  вл етс  следующее неравенство:The condition for the operation of the device is the following inequality:

где: Фр -магнитный поток, создаваемый рабочей обмоткой реле и пропорциональный левой частн равенства (1);where: Fr is the magnetic flux generated by the working winding of the relay and proportional to the left partial equality (1);

Фу -магнитный поток, создаваемый тормозной обмоткой реле иFu-magnetic flux generated by the brake winding of the relay and

пропорциональный правой части равенства (1).proportional to the right side of (1).

Выполнение неравенства,  вл ющегос  условием работы реле,The fulfillment of the inequality that is the condition for the operation of the relay,

соответствует нахождению конца вектора полного сопротивлени  Z в области , отмеченной на фиг. 2 штриховкой (зона блокировки).corresponds to finding the end of the impedance vector Z in the region marked in FIG. 2 shading (blocking zone).

Сдвиг по фазе вектора напр жени  U на угол а осуществл етс  с номощью конденсатора 6.The phase shift of the voltage vector U by the angle a is carried out with the help of capacitor 6.

Регулирование характеристики устройства может осуществл тьс :The adjustment of the characteristics of the device can be carried out:

1.Изменением соотношени  плеч сопротивлени  8, через которое1. The change in the ratio of the shoulders of the resistance 8, through which

протекает ток /;current flows /;

2.Изменением числа витков тормозной обмотки реле (или шунтированием ее);2. By changing the number of turns of the brake winding of the relay (or by shunting it);

3.Изменением коэффициента трансформации промежуточного трансформатора 5 напр жени .3. Changing the transformation ratio of the intermediate voltage transformer 5.

Тормозна  обмотка может питатьс  выпр мленным током, или она может быть включена иепосредственио в цепь переменного тока (см. фиг. 1).The braking winding can be powered by a rectified current, or it can be switched on and mediated in an AC circuit (see Fig. 1).

Предмет изобретени Subject invention

Устройство дл  блокировки действи  реле сопротивлени  в схеме релейной защиты, основанное на выделении определенной области действи  защиты в комплексной плоскости сопротивлений, отличающеес  тем, что, с целью расщирени  области действи  защиты в конце защищаемой зоны, применено электромагнитное балансное реле, включенное в цепь измерительных трансформаторов таким образом, что характеристика его действи  в комплексной плоскости сопротивлений имеет вид гиперболы,A device for blocking the action of the resistance relay in a relay protection circuit, based on the allocation of a specific area of protection in the complex resistance plane, characterized in that, in order to extend the area of protection at the end of the protected zone, an electromagnetic balanced relay connected to the measuring transformer is used the way that the characteristic of its action in the complex plane of resistance has the appearance of a hyperbola,
