High-voltage circuit breaker disk device with interlock function

This creation is a high-voltage circuit breaker disk device with interlocking function, which can improve the interlocking mode of the high-voltage circuit breaker disk, which is not limited by the size of the brand specification. The high-voltage circuit breaker disk has self-protection locking function and high-voltage circuit breaker. The disk and the high-voltage circuit breaker disk can be electrically and mechanically interlocked with each other, and can be interlocked for a long distance across the disk, which is easy to install and economical, and improves the safety of power consumption.

Xi has a high-voltage circuit breaker disk interlocking method, such as the world-famous brands ABB, Schneider, Siemens, etc., for the high-voltage circuit breaker disk and the high-voltage circuit breaker disk is generally similar to the steel cable, for the two (circuit breaker The mechanism between the back of the mechanism and the locking mechanism of the circuit breaker is interlocked to achieve the interlocking relationship, so there are special requirements in specifications, models and sizes. If it is not the same model and specification, it cannot be Interlock. If it is a different label, it cannot be used. It must be replaced by the whole group and cannot be effectively utilized. This is a common problem in the market.

At present, the interlocking mode between a plurality of high-voltage circuit breaker disks on the market is limited by the limitation of the high-voltage circuit breaker device itself, so the function of interlocking action in a mechanical manner has practical implementation difficulties. Therefore, the current practice is to achieve the above functional requirements by the control of the programmable controller PLC. But the programmable controller PLC itself must have power supply, If you are disabled, you may not be able to move. And the electronic method is also afraid of malfunction, and it is impossible to perform the interlock function between the high-voltage circuit breakers in a mechanical manner, which is a common problem when performing this function. Therefore, the use of mechanical methods for the interlocking function between the high-voltage circuit breakers has become market-oriented and urgency to improve the safety of the work, and the high-voltage circuit breaker disk device with interlocking function can improve the lack.

At present, the products on the market generally use two-wire interlocking mode for the interlocking device. The mechanical locking mechanism is used to lock the tripping mechanism of the high-voltage circuit breaker, or two of them are in the form of sheet metal. The high voltage circuit breaker locks the relative tripping mechanism or the input mechanism to achieve the interlocking function of the two high voltage circuit breakers. There are a number of disadvantages in this way that can cause inconvenience in use and limited functionality. For example, it is impossible to make electrical and mechanical interlocking functions in any position, any space, especially limited by size, brand, model, and specifications, and it is impossible to achieve the interlock function, so it is also economically impossible to reduce. The cost is even more difficult to standardize production. The above problems are difficult to overcome. Therefore, the high-voltage circuit breaker device with interlocking function is designed to improve the above-mentioned defects to meet the actual needs of the market, and to improve the safety quality.

At present, there are places where there must be interlocking between the high-voltage circuit breaker disk and the high-voltage circuit breaker disk, for example, the interlocking of two high-voltage generators with each other, and the mutual power supply system of the double-loop or higher in the high-voltage power circuit system Locks, such as power interlocks between double loop circuits.... The above power loop system uses multi-loop power supply in consideration of reliable reliability of power supply quality. Therefore, there must be an interlocking mechanism between the high voltage circuit breaker and the high voltage circuit breaker. At present, the high-voltage automatic switch (HV ATS) is generally used as an interlocking high-voltage control panel, which is bulky, expensive, and cumbersome to manufacture. And the high voltage circuit breaker in the control panel must be the same as the brand and the same Grid, the same size, and the same accessories, resulting in considerable restrictions on the actual use, and can not make any changes. Therefore, this problem has not been solved, especially when the load is changed, the existing equipment cannot be used, and the capacity equipment cannot be changed, the old and new models cannot be matched, and the presence space cannot be matched..., which causes many troubles, so there is a book. The creation of a high-voltage circuit breaker disk device with an interlock function can be used to solve the above problems.

In the high-voltage power system on the market, for three high-voltage circuit breakers above three circuits, it is difficult to perform three interlocking functions (Tie) between the three high-voltage power circuits. Especially when facing different system specifications, it is impossible to plan integration. In the actual state, the power circuit basically has some distance space. Therefore, when the connections between the three high-voltage circuit breaker disks are interlocked, they must all be concentrated in one disk or together. And there is no variety of choices in terms of specifications, and it is difficult to implement in practice. Therefore, if there is actual demand on the market, most of them currently use the programmable controller PLC as the electrical control interlock, but in terms of mechanicality, the interlocking function cannot be effectively and economically improved. The necessity.

This creation is a high-voltage circuit breaker device with interlocking function, which can improve the interlocking mode of the high-voltage circuit breaker disk, for example, using the high-voltage automatic switch (HV ATS) to make two interlocking locks; or use sheet metal Mode, steel cable type interlock; two sets of the same brand, specifications, size can be interlocked, three can not do the interlock function; and must be the same space constraints. The creation is not limited by the size of the manufacturer's specifications. The high-voltage circuit breaker has a self-protection locking function. The high-voltage circuit breaker disk and the high-voltage circuit breaker disk can be electrically and mechanically interacted with each other. The lock is not limited by space and can be interlocked for long distances across the disk, which is easy to install and economical, and improves the safety of electricity.
