Drawing unit The drawing unit is the supporting element for: The auxiliary voltage data is required to this effect. Documents Flashcards Grammar checker. Switch off the auxiliary voltage for the circuit-breaker drive and secure it against reclosing.

Vacuum circuit-breaker up to 36 kV

The rated current A is guarantied with force cooling in panel Rated current Rated short clrclut current 25 At the same time, check the position indicators and the areav in the circuit-breaker and with regard to other devices. Early 90s, winning odd brand of Schneider Electric’s first switch panel into China, the Chinese ended the era of using the light cord switch.

You must be familiar arega these interlocks before operating the circuit-breaker Electrical interlocks have been designed according to the circuit diagram. The drive mechanism is available in two basic models, i. The number of switching cycles can be used to draw conclusions about the service life or the operating hxv. The position of the auxiliary switch has changed. The switching functions have been set in the factory according to the wiring diagram.

Vacuum circuit-breaker up to 36 kV

For Schneider medium voltage switchgear and for panel builders. All dimensions not specified in detail are in millimeters. Schneider Electric China has nearly 22, employees. Circuit breaker is in discharge areeva open position,trolley is in service position.

The circuit-breaker must not be arevz for maintenance work see Disclaimer of liability,section 1. In this case, there are no insulating bridges between the phases. Cleaning agent, 1 liter can see Chapter 9. Appropriate interlocks rule out faulty switching operations. The HVX vacuum circuit-breaker must arevaa lifted in accordance with the illustration. Circuit-breakers and drives must not be disassembled for service and maintenance work see Disclaimer of liability, section 1.

Any damage occurred in transit must be recorded and reported immediately to the manufacturer.

HVX 12-17.5-24(technical instruction)

Any other use constitutes improper use and may result in dangers and damage. Depending on dirt collected, replace cloth as often as necessary.

This prevents continuous closing and opening “pumping”. It may only area used in the scope of the specified standards and the switchgear-specific technical data.

Observe the operating and locking conditions Chapter 7. Before performing work on the circuit-breaker, switch off the auxiliary voltage and prevent it from reclosing. The safety provisions of chapter 1. In case of frequent condensation or air pollution dust, smoke or corrosive gasesthe maintenance intervals must be adapted to the actual conditions. Aeeva symbol is used for information which is important to avoid damage. Auxiliary opening release F12 2.

These rules apply for the upper and lower circuit-breaker terminals alike. If additional control lines are placed in the drive casing, leave a sufficient distance from the movable parts of the drive.

On principle, general cleanliness of the circuit-breaker or of its external parts should be ensured. Auxiliary opening release 2.

The specific circuit diagram valid for the hv in question has been enclosed with each circuit-breaker. If voltage is applied to the motor, charging is performed automatically. Screw coupling between switching device and conductor bar with copper as conductor material. Circuit breaker storage with transportation of packaging that appears the question belongs to the consignee’s responsibility.
