Description

Disconnector fuse Product overview

HH15 series disconnecting switch fuse group and disconnecting switch (hereinafter referred to as switch) include QSA series, QA series and QP series, which are mainly applicable to distribution circuits and motor circuits with high short-circuit current, as the main switch or main switch operated infrequently by hand. QSA series switches can be used for circuit short-circuit protection.

The switch complies with GB/T 14048.3 and IEC60947-3 standards and is widely used in higher drawer type low-voltage complete sets.Suitable for multiple low-voltage distribution cabinets, details include: GGD low-voltage fixed switchgear, GCK withdrawable low-voltage switchgear, MNS low-voltage withdrawable switchgear, XL-21 power cabinet, etc

Disconnector fuse Normal working and installation conditions

The ambient air temperature shall not be higher than +40 ℃, not lower than -5 ℃, and the average temperature within 24 hours shall not exceed +35 ℃.

The altitude of the installation site shall not exceed 2000m.

When the ambient air temperature is +40 ℃, the relative humidity shall not exceed 50%. At a lower temperature, a higher relative humidity is allowed, for example, 90% at 20 ℃. Special measures shall be taken for condensation occasionally caused by temperature change.

The pollution level of the surrounding environment is 3 poles.

The switch shall be installed in a place without significant shaking, shock vibration and rain and snow invasion. At the same time, the installation site shall be free of explosive dangerous media, and the media shall be free of gas and dust sufficient to corrode metal and damage insulation.

Structural features

The switch adopts the front rotation operation mode, which is composed of operating mechanism, contact system, handle, etc.

The switch adopts a fully enclosed structure and is operated by spring energy storage. The closing and breaking speed of the switch is independent of the action speed of the operator, so as to ensure the safety of operators and equipment.

The switch is a contact system with unique performance. The moving contact system is directly formed from red copper bar. The moving contact piece is of bridge structure and has automatic adjustment function, so that it can effectively ensure line contact when connected with the static contact, thus ensuring the stability of product temperature rise.

The operating handle can be installed on the switch cabinet door. When the cabinet door is closed, the handle fits with the operating lever of the switch. When the switch is in the closed position, the handle is interlocked with the cabinet door to prevent the cabinet door from opening.

The switch is also equipped with an extension shaft, and the special length can be customized separately.

Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?

Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I
