Description

 Circuit breaker accessory assembly  

The invention relates to a combined device which can be combined with a circuit breaker, wherein all the accessories can be combined with the circuit breaker, in particular, the circuit breaker is used for any specification, and has the functions of external display and contact, and can be improved. A device that is safe and practical for electrical appliances.

The use of circuit breakers is a very common product, and circuit breakers can generally be divided into form-cavity circuit breakers (MCCB), or no-fuse circuit breakers (NFB). The former is a component title for products in Europe and the United States, and the latter is a product of the Japanese state. Another product classification name is Leakage Circuit Breaker (ELCB), which is a relatively small capacity circuit breaker commonly referred to as MCB and ELB. Usually MCCB and ELCB circuit breakers are used for large interrupting capacity, commonly known as industrial circuit breakers. While MCB and ELB are used for small interrupting capacity, they are commonly known as household light plug-in circuit breakers. Their functions are mainly an isolation switch that protects equipment and line safety. When an overload occurs, tripping isolation and fault current are generated. Safe trip isolation. In the case of ELCB, the protection function of leakage fault tripping is added. The circuit breaker is used in various places and is the main isolation switch in the world as a protection device and line safety. It is also the most versatile product in the world.

The use of circuit breakers is so common. At present, manufacturers of switchboards, due to space constraints, even because of economic cost considerations, most of the circuit breakers and circuit breakers in the entire switchboard and distribution box are adjacent to each other. After being fixed together, the plate is fixed on the plate fixing device. In Taiwan, on the primary side, copper bars are used as the conductive busbars (BUS), and in Europe, wire and cable are generally used as the power source for the primary circuit breakers. However, the connection power on the primary side, whether using copper bars or wires and cables, has almost no space between the circuit breaker and the circuit breaker inside the distribution box, and can be used as an additional function of the auxiliary function of the circuit breaker itself. When there is a new demand for functionality, there is almost no room for construction. In most cases, it is necessary to remove the copper platoon, remove the wire, remove the fixing screws, etc., remove all the equipment, remove the circuit breaker, install the required accessories, and then fix the circuit breaker in the distribution box. , redo wiring work. In addition to causing a lot of inconvenience, these can even cause a safety hazard.

In view of this, manufacturers of circuit breakers, such as world-renowned manufacturers Schneider, ABB, Siemens, singular, E-TN, SQ-D, Mitsubishi Electric, etc., respond to the customer's essential functional requirements for accessories, and the above The difficulty of actually changing the circuit breaker in the power distribution box body was first invented by the European and American manufacturers on the top of the circuit breaker body. There is a cover-type way to easily assemble a certain part of the common accessories to solve the future customer's cause. The troubles and inconveniences that arise when adding accessories must be added to functional requirements. At present, this method of solving the problem and the actual product are also the manufacturing methods that the circuit breaker manufacturers all over the world consistently follow, and are the mainstream of circuit breaker product design.

The main accessories of the circuit breaker are mainly the following items; one is the auxiliary contact switch (AUXILIARY SW, abbreviated AUX SW), which acts as the state that the circuit breaker is closed ON or the OFF is turned off. The second is the alarm contact switch (ALARM SW, abbreviated AL SW), which acts as the fault status indication of the circuit breaker tripping trip. The third is the Shunt Trip Device (SHT), which functions as a device that uses a power source to supply the tripping component to actuate the internal tripping mechanism of the circuit breaker to perform tripping. The fourth is the Under Voltage Trip Device (UVT). When the system voltage drops to a certain limit due to a fault, the UVT will act to make the circuit breaker trip. The fifth is a padlock device. In order to meet the requirements of regulations and public safety, it is generally a device that closes ON, turns off OFF, trips Trip, and 1 to 3 locks. Six are the functions of the under-phase protection. Seven is an electric operating device, which is used for various conditions, and is equipped with a remote control electric operation function for the circuit breaker. For example, it is used in the motor centralized management panel MCC, or other special functions such as the special occasion of the industrial machine. The above seven accessory products are the most commonly used products for circuit breaker accessories, and there are urgent and necessary functional product requirements on the market.

Circuit breaker products, with the advancement of materials application technology in the world, and the advancement of technology and environmental changes in the world, such as electronic information and frequency conversion technology, such as the use of nonlinear components, resulting in power quality problems... ...etc., as well as the requirements for special functions and requirements for differentiation, each manufacturer has become more compact, electronic, and communicable, etc., resulting in product diversification and size of circuit breakers that cannot be standardized and unified. It has also caused even the cover of the circuit breaker product to be covered, but its accessories are not uniform due to different sizes and specifications. As a result, the circuit breaker manufacturer's model products are complicated, and it is impossible to unify and standardize, resulting in economic waste, and it is very inconvenient for the customer to use. Therefore, the problem must be changed in the accessory combination method and method of the circuit breaker. To overcome the above difficulties.

Actual customer power consumption conditions are different, and the use of circuit breakers is different. Even some circuit breaker manufacturers can only describe the catalogue specifications as "chaotic", so that in combination with the above factors, customers often need to be disconnected. It is difficult to add attachments, even to renovate, or to face the fate of having to redo.

Based on the above analysis, the present invention proposes a universal accessory combination method to solve the problem that the customer needs to increase the accessory device due to the circuit breaker, and can overcome the problem of adding accessories of different specifications and sizes of different manufacturers.

The position of the circuit breaker handle after the displacement is operated, and then the function of the auxiliary contact and the alarm contact can be achieved by connecting the output line to the terminal block by the action of the micro switch.

In order to achieve the function of the branch tripping device, the method used is different from the traditional flipping method or the upper cover of the circuit breaker. Each circuit breaker can be used with a test trip button (IEC regulations for circuit breaker manufacturers worldwide) There is a mechanism for simply testing whether the mechanical structure of the circuit breaker is faulty or not, and a transmission mechanism is connected by a coil. When the power is turned on, the pressure bar on the transmission mechanism is pressed to the trip button to make the circuit breaker jump. Take off and connect the outlet or to the terminal block.

In order to achieve the function of the insufficient voltage tripping device, the method used is different from the traditional flipping method or the upper cover of the circuit breaker, and the test trip button on the circuit breaker is used, and the action mode is just opposite to the split trip device. When the power is normally applied and the normal voltage value, the transmission mechanism does not operate. However, when the voltage value is lower than the set normal value, the transmission mechanism is actuated, and the pressure bar on the transmission mechanism is pressed to the trip button to make the circuit breaker trip, so as to achieve the functional requirement of insufficient voltage tripping, and the connection is made. Wire or to the terminal block.

In order to meet the requirements of the circuit breaker locking device, an appropriate locking device can be placed above the fixed plate, and the function of the movable displacement of the circuit breaker handle can be locked at the position required by the function, whether it is closed or not. It is turned off and OFF, and it is better to have the function of electrical and mechanical function points.

In order to achieve the function of under-phase protection, it is possible to add components with under-phase fault trip protection in the box of the circuit breaker accessory assembly device to achieve the protection of the device.

Due to the above-mentioned accessory function, many accessories must occupy the space above the circuit breaker, so the handle of the original circuit breaker is not well operated, so the handle of the circuit breaker can be connected and lengthened to facilitate the combination with other functions. In addition, two solenoid valves can be arranged on the two sides of the handle, and a connector for operating the handle of the circuit breaker is arranged in the middle to achieve the function of electric operation. Moreover, it can solve the shortcoming that the volume is too large, generally driven by an electric motor, via a gear drive handle.

The accessories of the above circuit breakers can be combined above the circuit breaker or next to the circuit breaker (the space condition allows), so that the design requirements derived from the previous accessories for adding the circuit breaker can be solved, and it is better to have the function connection. Point output, whether wired or wireless, enhances the application design of other functions.
