CT Series Power Transmission Line Energy Acquisition Devices
1. The principle of CT power supply
CT power supply, that is, use the CT installed on the power line as a device to obtain power. The power supply is divided into two parts, one is the CT used to obtain electricity, and the other is to convert the electrical energy obtained by the CT into the required DC voltage and current power supply module.
Application range:
The CT power supply is mainly used on power lines, which can solve the problem that the equipment cannot get other power supply.
3. Technical Features
1) Since the CT is installed on the power line cable, its insulation is relatively high
2) CT power installation is more convenient, and the price is low.
3) It is more suitable for the power supply of low-power equipment
The application range of ct series power transmission line energy acquisition devices includes: Power equipment installed on the high-voltage side of high-voltage transmission lines: wire temperature, breeze vibration, galloping, secondary pitch oscillation, tension, and ice monitoring devices on high-voltage overhead transmission lines. Power equipment that is difficult to obtain power near high-voltage transmission lines: various monitoring devices on underground power cable lines, monitoring equipment in ring network cabinets, etc. Performance characteristics: Inductive energy extraction, high efficiency and reliability, maintenance-free open-type energy acquisition transformer, easy to install, simple wiring, the energy acquisition module adopts metal shielding package, good airtightness, adapt to harsh environments, stable operation, and can work under the condition of line current changes The stable output adopts switch-type regulated voltage standard design, the output voltage is stable, the ripple is small, the maximum output power can reach more than 150W, it can work continuously at 3000A current, and it can be installed on the transmission line of any voltage level from 6kV to 500kV.
Feature:
1. Reasonably select the induction power supply and its energy storage components according to the conventional operating value of the wire current, power curve and electric power;
2. Due to the magnetic circuit, there will be a slight ticking sound when the energy transformer is working, which is a normal phenomenon;
3. The principle of the induction power supply module is completely different from that of the conventional power supply, and it must not be connected to other power interfaces;
Parameter:
| Model | Input current(A) | Output current | accuracy |
| HMKCT-45HW | 300A-2000A | 5A/1A | 0.5 |
| HMKCT-55HW | 400A-1000A | 5A/1A | 0.5 |
