          Drjsq arrester discharge counter

          Product ID:DR-JSQ-005    Released in:2021-8-24    Click:152    Brand:Deng Rui Electric   【See product catalog

          Drjsq arrester discharge counterDetails:

          Electric Co., Ltd. Yueqing Dengrui factory direct【Drjsq arrester discharge counter】,And provide a variety of【Drjsq arrester discharge counter】Images, parameters, description and other detailed product information,Dengrui【Drjsq arrester discharge counter】High quality, excellent price, special requirements can be customized consultation.

           1、 Purpose
          Drjsq arrester discharge counter is a high-tech electronic instrument which connects high-precision digital collector in series with the grounding wire of arrester to monitor the discharge times and time of arrester,
          Drjsq type arrester discharge counter can completely replace common js-8 discharge counter and JCQ arrester monitor. The substation has a simple and convenient communication interface, which can be used to monitor the number of times of action and intelligent communication system.

          2、 Working principle of the device
          Drjsq type arrester discharge counter is mainly composed of high-precision digital collector and intelligent display unit. The arrester is grounded through the device with high-precision digital collector. The digital collector collects the discharge current signal of the arrester, and transmits the data to the central processing unit of the device through the isolation conversion unit, so as to record the action times and action time of the arrester.

          3、 Product functions and features
          Drjsq type arrester discharge counter can record the discharge times sensitively and accurately. The monitor has the advantages of accurate counting, large storage capacity, intelligent query, simple display interface, small structure and panel installation. The performance of drjsq arrester discharge counter meets the requirements of JB / t10492-2011 monitoring device for metal oxide arrester. Its main performance: discharge counter in the waveform of 8 / 20us, amplitude: 50A ~ 100kA, can accurately and reliably act, low residual voltage, has a great current capacity.
          1. Strong anti-interference ability, input signal range: 0.1mA ~ 200A;
          2. It has the function of checking the fault records of discharge times and discharge time;
          3. The clock in the device can still ensure accurate timing after power failure, without power down reset. The memory data has power-off protection function, which can ensure that the recorded data will not be lost within the storage period (100 years);
          4. RS485 communication interface can realize multi computer communication or communication with upper computer, which is suitable for intelligent substation

          4、 Installation and dimension
          1. Installation instructions
          Three high-precision data collectors are installed on the grounding wires of phase a, phase B and phase C respectively.

          2. Dimensions
          Drjsq type arrester discharge counter intelligent display unit is installed on the panel of switch cabinet, and the opening size is 111 × 111mm. (width × height), overall dimension 120 × 120 × 90 (width × height × depth).
