With the expansion of motor production to a new energy system and a new energy landscape, the use scenarios of the basic sensors of production workshops have changed. Extended charging stations and intelligent distribution chambers. As a complete solution provider, your company needs to deploy a unified current transformer for switchgear core component in different electrical environments. This article demonstrates HYCA’s ability to cover the entire activity from three main scenarios.
1. Application scenarios for charging new energy
In the actual work of urban public charging stations, the variable charging chambers have to deal with the liquid DC component, which is discharged from the built-in charger in addition to the variable current.
1.1 Actual working conditions at the charging station
When the charging gun is used for charging into the car, when a conventional split core current transformer with leakage protection type A is used inside the dome, will cause a leak of several milliamps DC on the vehicle side to saturate the core of the converter in one direction. If the charging gun cable is damaged and causes an electrical alternating shock during this time, the protective device refuses to move due to a magnetic core failure. This working condition has been considered as a point of refusal of acceptance by IEC 62752 and IEC 62955.
1.2 Dissolution of HYCA in the assembly of the production line and the operation of the station
On the production line of the charging station, the PCBA HYCA-01 is welded directly between the AC input station and the main connection, and the main connection is fully accelerated without the need for external current transformers and secondary lines. When the station is in operation, when a DC leak greater than 6mA is detected, the level of the X6-OUT devices changes and interrupts the circuit. During uninhabited nights, the TEST IN mirror starts the simulated leakage current, automatically completes current transformer for switchgear link diagnosis, and reports to the cloud.
2. Application scenarios for control cabinets in industrial automation
In the central control hall of the vehicle welding line and the food filling workshop, low-voltage cabinets require a large number of frequency conversions and server circuits manage.
2.1 Complicated load control on the workshop side
In the actual workshop work, a large number of frequency converters are applied to the DC components of the incoming main line. HYCA is installed at the bus location in the incoming low voltage cab and is responsible for controlling the incoming main line. When equipment fails due to a coolant leak, the double-threshold output allows the engineer involved to quickly determine the type of leak.
2.2 Row coordination with switchgear converters
In the distribution system, the HYCA wood is placed in the main entrance cabinet and the conventional control components are configured in the branch cabinets. If the department fails due to a circuit breakdown failure, the HYCA master cabinet acts as a backup to perform a delayed connection breakdown, to prevent the error from spreading. This sequence logic is based on the precise determination of the current transformer for switchgear and meets the stringent requirements of foreign markets for selective protection of factory distribution levels.
3. Application scenarios for motor control and variable frequency speed control
In populated areas such as air compressor stations and cooling towers, real-time monitoring of the insulation state determines the likelihood of an unplanned shutdown.
3.1 Internet isolation control of frequency device motors
When the frequency converter leads the cooling tower fan, PWM pulses generate a leakage current through the distributed damage capacity. HYCA is mounted on the output side of the frequency device, with a broadband response, constantly monitors trends and activates warnings about the occurrence of short circuits between cycles.
3.2 Damping of the power column of the servo motor and central control of the control of the team
In the printing press scenario, the HYCA servo acts as a motor current sensor and provides PWM responses to DC warnings. The driver adjusts the modification strategy accordingly to limit the electric corrosion of the bearings. Division of an HYCA in the bus band input of a multi-provider assembly line as a central node of the current transformer for switchgear. When a wrong leak occurs, the PLC starts and keeps in line to determine the fault location and reduce the overall cost of protection.
In short, the HYCA series includes three main scenarios: chargers, industrial control and motor drive, providing a reusable current transformer for switchgear hardware platform for the electrical group.
