Product Description

  DXK-ZY high-voltage charged display is a new type of device to prevent electrical misoperation. It is an inductive (non-contact) high-voltage charged detection device. The device has advanced design, reasonable structure, complete functions, safety and reliability. It has functions such as flashing display, audible alarm, fault self-test and activation of forced blocking circuit, etc., and has high sensitivity and reliability. This device is suitable for outdoor (also suitable for indoor) electrical network or equipment with AC 50Hz and rated voltage of 40.5 ~ 1100kV, and it is used to reflect the charged condition and prevent electrical misoperation. The device is installed on the line grounding knife switch, the bus grounding knife switch and the busbar pressure change grounding knife switch, and can prevent the misconnection of the grounding knife switch when it is charged. This device can cooperate with anti-error devices such as electromagnetic locks, mechanical program locks, and microcomputer locks to implement compulsory lockout. It is an ideal safety device for preventing electrical misoperation on outdoor (indoor) electrical networks or equipment.
  The sensor of this device adopts the induction electric field method, which does not directly contact the charged body. The installation is simple and convenient, the maintenance cost is low, the service life is long, and it is safe and reliable.

  1. Sensor starting voltage: 0.1 ~ 200V adjustment.
  2. Output relay with live state of each phase: 220V / 1A.
  3. Blocking relay output relay: 220V / 5A.
 
  Structural features
  Display: closed, miniaturized;
  Sensor: built-in electric field induction type;
  Latching unit: With latching contact, when one phase is charged in the three-phase line, the latching relay will be forcibly locked. Only when there is no voltage in the three-phase online detection, the latching relay contact will open.
  Glow: Red strobe light;
  Snoring sound: continuous short whistle, no less than 67dB at 30cm from the display.
  High reliability and good safety: Inductive sensor, high sensitivity, safe and reliable;
  Good economy: The sensor does not come into direct contact with the charged body, no partial discharge test is required during installation and maintenance, simple and convenient, low maintenance cost and long service life.
  Complete functions: with multiple functions such as flashing, fault self-diagnosis and forced lockout;
  Good adaptability: various forms, which can be widely used in indoor, outdoor, GIS combined electrical appliances and switch cabinets and other places.

Intelligent detection is a major issue for the planning and construction of the ubiquitous electric power Internet of Things system by the State Grid Corporation of China. It is also a key application for solving the problem of interconnection and data sharing of the operation inspection system. It is also an important basis for the practical application of big data analysis for equipment inspection.

A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are a primary coil, a secondary coil, and an iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. It is a key device in the power system. Generally, transformers rarely fail. Once a certain defect occurs inside the transformer equipment, equipment failure is extremely easy to occur. Therefore, strengthening and improving the operation monitoring of transformer equipment is of great significance for ensuring the safe operation of transformers.
