The problem of power safety production of high-voltage switchgear is the problem of power inspection

The high-voltage switchgear has a problem of power safety production that has been difficult to solve for many years, that is, the problem of power inspection. The mechanical locking devices of the first fully enclosed high-voltage switchgear of the inflatable high-voltage switchgear have the function of five prevention, which can not meet the safety regulations of the manufacturer of the first 10kV high-voltage switchgear and then the grounding wire, The enclosed high-voltage switchgear has always been in a fully enclosed state. If the normal operation method cannot test the power of the equipment, it will appear that the cabinet door of the high-voltage switchgear can only be opened for power test. In case of power failure, it is necessary to check whether the equipment has voltage before it can be switched on and off.

From an objective point of view, the old device does have many problems. We need a new type of live display device with long maintenance free, long service life and clear display. This new type of live display device is used together with the sensor. We can use the on-site electrical inspection method to see whether this high-voltage equipment has the electrical locking ability.

This device also solves many problems of neon lamp live display device, is suitable for use in various light operating environments, and has an outgoing independent power inspection function, which greatly improves the availability of power inspection basis of this device. This device also has digital locking control technology, which can ensure that the locked voltage of system abnormal operation remains unchanged and can operate stably.

"Stable quality and customer first" has always been our business purpose and philosophy. We have won the sincere cooperation and trust of customers with excellent product quality and perfect pre-sales, in-sales and after-sales service.
