DINKONDA GLOBAL Power Plants Special High-power DC Distribution System SVM51G-630PT DC Plastic Shell Isolation Switch Rotating Disconnector

Product Overview

SVM51G-630PT DC plastic shell isolation switch is a plastic shell DC isolation device developed specifically for high-power DC distribution systems. This product uses a plastic shell as the carrier and can form a visible and reliable isolation fracture at the opening position. It is mainly used for safe maintenance and isolation of DC circuits such as photovoltaic, energy storage, and DC distribution cabinets, achieving circuit connection and disconnection under no load and providing electrical and gas safety breakpoints for backend equipment maintenance. The product does not provide short-circuit protection function and is often used in conjunction with DC circuit breakers and fuses to meet the safety requirements of "obvious disconnection points" for DC system maintenance.

Structural Composition

1. * * High strength flame-retardant plastic shell**
The shell is made of high-temperature resistant and flame-retardant engineering plastic, which has excellent insulation performance and mechanical strength, anti-aging, arc resistance, and can adapt to the long-term working environment in the cabinet; A busbar connection hole is reserved at the top and bottom of the shell for easy assembly of copper busbar wiring. The side of the shell is equipped with a heat dissipation rib structure to reduce the temperature rise during long-term high current operation.

2. * * Main contact and isolation fracture mechanism**
Internally configured with dedicated DC static and dynamic contact components, forming a visual disconnect gap in the open state to meet power safety isolation standards; The contacts are made of highly conductive and oxidation resistant alloy materials to reduce contact resistance and minimize long-term current carrying heating.

3. * * Manual operating mechanism**
Adopting a direct manual operating mechanism, the front is equipped with an operating handle, and red and green markings clearly distinguish the closing and opening positions; The mechanism is equipped with mechanical limit to ensure proper locking and prevent misoperation. The handle has a stable operating feel and can quickly complete the opening and closing operations.

4. * * Status indication module**
The panel integrates a mechanical position indicator window, which can intuitively feedback the opening/closing status of the switch, truly reflecting the position of the internal contacts, and is not affected by external forces on the operating handle.

5. * * Optional auxiliary contact module**
Auxiliary switches can be installed to extract passive signals from the opening and closing positions and upload them to the backend monitoring system, enabling remote monitoring of switch status.

Core Features

1. Clear and visible isolation fracture, safe and reliable maintenance**
After disconnection, there is a clearly visible disconnection point, which meets the safety regulations for DC power maintenance. During maintenance operations, the upstream power supply is effectively isolated to ensure the personal safety of operation and maintenance personnel.

2. * * Specially designed for DC working conditions, with strong current carrying capacity**
Optimized contacts and conductive circuits for high DC current operating conditions, with a rated current of 630A, low circuit contact resistance, excellent long-term current flow temperature rise control, and suitable for long-term continuous operation of energy storage and photovoltaic high-power DC circuits.

3. * * Compact plastic shell structure, easy cabinet installation**
Plastic shell integrated design, compact size, small installation space, standard fixed installation, can be directly installed in DC distribution cabinets, suitable for standardized layout of complete cabinets.

4. * * High flame retardant insulation shell, strong environmental adaptability**
The shell has high flame retardant grade, stable insulation performance, can adapt to indoor distribution cabinet environment, withstand temperature changes, dust environment, and has excellent anti-aging performance.

5. * * Optional auxiliary signal output, supporting intelligent monitoring**
Configurable auxiliary contacts, real-time upload of switch on/off status signals, connected to SCADA monitoring system, to meet the intelligent operation and maintenance needs of energy storage and photovoltaic power plants.

6. * * Mechanical interlocking protection to prevent misoperation**
The operating mechanism has a built-in mechanical limit structure, and the opening and closing positions can be locked to prevent unauthorized misoperation; Can be equipped with a padlock device, which can be locked in the open position during maintenance.
