What does the intelligent system deployment for low-voltage switchgear include?
The perception layer is the foundation for intelligent transformation, requiring the installation of highly reliable sensors and smart components without compromising the original explosion-proof structure of the switchgear.
What are the common faults of low-voltage switchgear?
Low-voltage switchgear is a critical piece of equipment in power systems, used for distributing electrical energy, controlling circuits, and protecting electrical devices. However, during operation, low-voltage switchgear can experience a variety of faults.
What is the selection guide for knife switches?
Selecting a knife switch requires careful consideration of multiple factors. Here's a detailed selection guide:
What are the structural features of a knife switch?
A knife switch (also known as a blade switch) is a common low-voltage electrical device primarily used for connecting and disconnecting circuits. Here are the main structural features of a knife switch:
What are the acceptance criteria for distribution boxes?
Production Qualifications: The manufacturer of distribution boxes and cabinets holds all necessary production certifications, including a production license, as well as technical and quality assessments approved by specialized national institutions, along with relevant accreditation documents.
What is the short-circuit breaking capacity of the distribution box?
The short-circuit breaking capacity of a distribution box refers to the ability of its internal circuit breaker or fuse to quickly disconnect the circuit in the event of a short circuit, thereby protecting equipment and ensuring personal safety. Here’s some relevant information about the short-circuit breaking capacity of distribution boxes:
What is the protection rating of the distribution box?
It prevents solid objects larger than 12.5mm from entering, but has no waterproof capability. Ideal for dry indoor environments such as typical homes, offices, and similar settings.

What issues should be considered during the installation of a box-type substation?
Technical Preparation: Construction personnel must thoroughly review the construction drawings and gain a clear understanding of the box-type substation’s model, specifications, technical parameters, and installation requirements. Additionally, a technical briefing should be conducted for all workers to ensure everyone comprehends the construction process, quality standards, and safety precautions.
What is a high-voltage switchgear? What is its primary function?
Opening and closing circuits: Circuit breakers and disconnect switches in high-voltage switchgear control the connection and disconnection of electrical circuits. For instance, in a power plant, circuit breakers can connect or disconnect generators from the power grid, enabling the transmission and distribution of electricity.
