Description
(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ СКОРОСТИ ИЗМЕНЕНИЯ МОЩНОСТИ ЯДЕРНОГО РЕАКТОРА(54) DEVICE FOR MEASURING THE RATE OF CHANGE IN THE POWER OF A NUCLEAR REACTOR
II
Изобретение относитс к области дерного приборостроени и предназначено дл применени в систе.мах контрол дерных реакторов дл измерени скорости изменени мощности дерного реактора.The invention relates to the field of nuclear instrumentation and is intended for use in nuclear reactor control systems for measuring the rate of change in nuclear reactor power.
Известно устройство дл измерени скорости изменени мощности дерного реактора , содержащее измеритель периода, на вход которого поступает сигнал, полученный от суммировани двух логарифмических сигналов 1.A device is known for measuring the rate of change in the power of a nuclear reactor, containing a period meter, at the input of which a signal is received, obtained from the summation of two logarithmic signals 1.
Недостатком известного устройства вл етс то, что точность измерени периода давлени зависит от настройки характеристик и стабильности коэффициентов усилени предыдущих каскадов.A disadvantage of the known device is that the accuracy of the measurement of the pressure period depends on the tuning of the characteristics and the stability of the gain factors of the previous stages.
Наиболее близким по технической сущности к предлагаемому изобретению вл етс устройство дл измерени скорости изменени мощности дерного реактора, содержащее импульсный и токовый логарифмические измерительные каналы, к выходу которых подключаете через коммутатор измеритель периода.The closest to the technical essence of the present invention is a device for measuring the rate of change in the power of a nuclear reactor, containing pulsed and current logarithmic measuring channels, to the output of which you connect a period meter via a switch.
Недостатком известного устройства вл етс бросок сигнала на выходе измеритеЛЯ периода при переключении с одного измерительного канала на другой, что вызвано подключением к разным уровн м выходных напр жений каналов.A disadvantage of the known device is a surge signal at the output of the period meter when switching from one measuring channel to another, which is caused by connecting the output voltage of the channels to different levels.
Целью изобретени вл етс повышение достоверности информации.The aim of the invention is to increase the reliability of information.
Поставленна цель достигаетс тем, что предлагаемое устройство содержит первый и второй конденсаторы, подключенные одними обкладками к выходу импульсного и токового каналов, а другими к входу первого и второго коммутаторов, управление которыми осуществл етс компаратором, причем коммутаторы- поочередно подключают обкладки конденсаторов к первому резистору , включенному последовательно со входом операционного усилител , и к разр дному резистору. Обкладка конденсатора, отключаема от первого резистора, соедин етс через разр дный резистор к точке с нулевым потенциалом.The goal is achieved by the fact that the proposed device contains first and second capacitors connected by some plates to the output of the pulse and current channels, and others to the input of the first and second switches, which are controlled by a comparator, and the switches alternately connect the plates of the capacitors to the first resistor, connected in series with the input of the operational amplifier, and to the discharge resistor. The capacitor plate, which is disconnected from the first resistor, is connected through a discharge resistor to a point with zero potential.
На чертеже показана структурна схема устройства.The drawing shows a block diagram of the device.
Устройство состоит из импульсного 1 и токового 2 логарифмических измерительных каналов первого 3 и второго 4 конденсатоThe device consists of a pulsed 1 and current 2 logarithmic measuring channels of the first 3 and second 4 condensates
