This creation relates to an industrial type circuit breaker handle locking device, which is suitable for circuit breaker installation and locking device, can be standardized assembly, improve assembly efficiency and aesthetics, and meet safety requirements.

Based on the enthusiasm for improving industrial safety and the experience of on-site implementation, this author has a series of inventions and creations on motor switch and power supply management. More than a dozen of these research and development results have been patented and approved. In particular, the author of this creation has provided a series of practical motor switch locking devices, which can be used in combination with various brands and models of motor switches, with good results. The author of this creation has this series of inventions and creations on the safety of motor switches. In view of the many electrical accidents in the past and abroad, they have occurred in the maintenance events of motor machinery, mainly lacking practical motor switch locking devices. However, the improvement of the locking device applicable to various circuit breakers has not been solved.

The "Electrical Safety Technical Information" published by the Labor Safety and Health Research Institute of the Executive Yuan Laboratories in 1999 was published in a research report hosted by Su Wenyuan. "Electrical accidents have always been one of the main causes of accidental injuries. Labor protection should be avoided as much as possible. The main cause of electric shock accidents is the lack of awareness of electrical safety by public institutions and labor, which causes potential dangers such as unsafe environment and unsafe behavior at the work site. "There are two common electrical safety hazards." Kind of, the first is from the use of electrical machinery, and the second is the negligence in electrical work. In order to remedy the lack of awareness of electrical safety in public institutions and labor, and to prevent the use of electrical work, it is necessary to have safety facilities in Article 45 of the Labor Safety and Health Facilities Regulations to further regulate the use of electrical machinery by employers. That is to say, if there is a significant risk to the machine using the power running, the emergency braking device with the obvious mark should be installed at the appropriate position to immediately interrupt the power and interlock with the braking system, and can quickly stop the operation of the machine in an emergency. In addition, in the case of preventing the use of electrical work, in the case of power outages, Article 254 of the "Labor Safety and Health Facilities Regulations" stipulates that the employer engages in the circuit, the circuit support, or the circuit after opening the circuit. When the work is laid, constructed, inspected, repaired, painted, etc., after confirming that the circuit is open, the switch shall be opened for operation in the circuit. It shall be "locked" or marked as "no power transmission" or "blackout operation". Or set up facilities for monitoring personnel. In the first kind of disaster from the use of electrical machinery, the cause is that almost everyone has insufficient knowledge of the principle of electrical safety to interrupt the power. Although Article 254 of the "Labor Safety and Health Facilities Regulations" further stipulates that the switch to open the circuit should be "locked" in the operation, but so far, the "locking" regulations are often empty talk. There is no real implementation.

The shunt switch or circuit breaker used as an isolation device in accordance with International Electrotechnical Regulations NEC.422.31. (430.102) (440.14) shall have a locking device. The location of the isolation device is occludable when it is within the visible range of the electrical appliance or when it is open. The locking device mechanism should be in place. Its regulatory principles and uses are to prevent accidental power transmission and reverse power transmission (without affecting public safety!):

1. The private indoor distribution board does not need to be locked.

2. The electricity used in public places should be locked.

3. The motor centralized control panel can be locked with the switch handle.

4. There will be dangerous situations after locking and cannot be locked!

The locking device is designed to prevent accidental power transmission, reverse power transmission, etc., because the eye vision may not be seen, and danger may occur, so it is desirable to lock during maintenance to ensure safety. In view of this, manufacturers of switches in the world have production-related products. These include external plug-ins, internal keys, and so on. Also in OSHA, fire law regulations, etc., there are mandatory rules and penalties.

The commonly locked switch is a circuit breaker, and the circuit breaker products have become more and more difficult to use with the advancement of technology in the world due to advances in materials application technology, as well as advances in the world, such as electronic information and frequency conversion technology. The more and more, the quality problems of electricity, etc., as well as the requirements for special functions and requirements, etc., each manufacturer has become a product of circuit breakers in addition to products becoming smaller, electronic, and communicable. Diversification and size cannot be standardized and unified, and even if the circuit breaker product casing is covered, the technology and the material used in the circuit breaker itself will affect the appearance of the circuit breaker itself, resulting in the size and specifications of the accessories. The same, but not universal. As a result, the circuit breaker manufacturer's model products are complicated, and it is impossible to unify the standardization, resulting in economic waste, and it is very inconvenient for the customer to use.

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 must 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 to redo the wiring. In addition to causing a lot of inconvenience, these can even cause a safety hazard.

From the specifications of countries around the world, such as IEC, JIS, EN, CE, UL, CSA, GB, CCC, CNS, etc., in the manufacturing process of switches, the requirements of specifications, and the differences in characteristics and functions, and Depending on the technical capabilities of the manufacturer, it is possible to obtain more advanced materials applications, as well as the use of advanced technology equipment and advanced experimental test equipment. In the actual situation, due to the above differences, each switch has a different height, the upper cover and the lower cover are different, and due to the difference of the first two, the design and the shape of the upper cover are completely different, and the size and size are different, and There are more than a thousand circuit breaker manufacturers in the world, which are different in image design, so the design is different, so that even in the patents and designs of No. 105213785, No. 105214529, No. 105215789, No. 106200125 I have tried most of the same and tried to make it universal. However, in practical applications, there are still many difficulties, that is, it is impossible to solve all the problems in the actual situation in the market. In particular, this case is a way to solve the above-mentioned four patents and the actual conditions that cannot be solved by the prior patents.

Because there are too many manufacturers of circuit breakers in the world, at least a few hundred or more, the specifications, sizes, sizes, etc. of the manufacturing are different. Even if the appearance looks "small", it seems that the difference is not big, in fact, it is completely different. If it is solved in the past, the conclusion is "impossible task", so there are more than a few hundred open molds, and it is still impossible to reach the specifications of one thousandth of the market. In view of this, we have redeveloped a problem to improve the above problems. Design has become a necessary and urgent focus, to solve the market's work safety improvement needs and to avoid the repeated investment in the development of individual mold resources, becoming an important issue. Especially the height part of the circuit breaker, except 60, 68, 86, 105, 140, 210 (mm), etc., in the case of differentiation, there are also some differences, there are several specifications in the width of the above, 26, 33, 41 (mm) ... and in the area of the handle area There are more than three different types of industrial circuit breakers in the world (generally divided into 250AF or less, 400/630AF, 800AF or more), as well as different ways of distinguishing the upper cover image and the internal jumping mode. The mechanical stress is different when jumping off. The above five different parameter specifications have caused the improvement method developed in the past, and it is impossible to solve the problem of the effective replacement of the ground and the standardization of the circuit breaker locking device. Therefore, there is an improvement plan for this creation. .

The main purpose of this creation is to provide a locking device using a circuit breaker handle, which is simple in construction and convenient to install. The locking device solution for industrial type circuit breakers of any brand, specification and size can be used in all directions, and can be locked in both ON and OFF positions, making the installation of the locking device of the handle universal. Sexual and practical convenience, suitable for all sizes and shapes, and can greatly improve the safety of the use of electrical equipment.

In order to achieve the above purpose, the industrial industrial type circuit breaker handle locking device can combine a lock with an inverted L-shaped plate body to form a combination of the locks on the inverted L-shaped plate, because consideration In order to solve the above problem, the lock locating hole under the fixed lock can be made into the upper row and the lower row when the bottom of the circuit breaker body is asymmetrical, so that the left and right sides of the lock can be used, and Below the plane in which the lock and the inverted L-shaped plate are integrated, two rows of test reserved holes are placed, and the test reserved hole is symmetrical above and below, so that the problem of blocking the trip button switch and the left and right can be solved. Problems to be shared, party When the LED is closed, it can be tested whether the circuit breaker will trip. In this way, the problem of the difference in width and shape and the asymmetry of the circuit breaker can also be solved. When the inverted L-shaped plate is combined with the long-shaped fixing box, the assembly is completed.

In order to achieve the above purpose, the inverted L-shaped plate of the industrial type circuit breaker handle locking device is an inverted L-shaped rigid plate, and two rows of elongated adjustment holes are arranged below the other side of the non-installed lock. It can have two holes or four holes to achieve the function of fine-tuning the height up and down. It can improve the problem of re-machining or increasing the height of the pad in the past. It can completely solve the problem of different heights, or it can be solved by modeling problems such as curved and wave-shaped. Different modeling problems, etc., and can be used to fine-tune the function. This method can also solve the problem of height and shape. When the inverted L-shaped plate is combined with the long-shaped fixing box, the assembly is completed.

In order to achieve the above purpose, the creation type industrial circuit breaker handle locking device can make an object combining the inverted L-shaped plate and the lock, and then make a long fixed box, and the long fixed box has a long strip type Introducing a hole, the inverted L-shaped plate can be placed in the elongated fixing box, and an auxiliary side cover is arranged on a side of the elongated fixing box, and can be fixed by four bolts to form a main body fixing box; a height positioning hole having a tapping thread on a side of the main body fixing box member, when the lock lever on the inverted L-shaped plate is aligned with a center point position of the movable area of the handle of the circuit breaker, and the inverted L-shaped plate is The side having the long-shaped adjusting hole is placed in the long fixing box through the long-shaped introduction hole on the long fixing box, and the four fixing bolts can be tightened, and then the auxiliary side cover is sealed. The auxiliary side cover has a fixing hole for fixing the bolt to the main body fixing box member, and on the upper and lower sides of the long type fixing box, each has a fixing hole for fixing to the box sheet metal or the circuit breaker, when the position is Determine the long fixed box The upper and lower device fixing holes are bolted to the box sheet metal or the circuit breaker, and then plugged with a plug on the top to prevent others from using it. The tool is actuated to cause displacement or damage; or more than one fixed support point is sought on the industrial type circuit breaker and more than one fixed point is sought on the industrial type circuit breaker, which may be a fixed bolt or a fixed column The body is a fixed component, forming a stable supporting surface, and is plugged with a plug above the fixing bolt to prevent others from using a simple tool to move or displace or break; if it is a common size, the inverted L type can be used. The plate is integrally fixed with the long fixing case, and is standardized and solidified. And in accordance with international regulations, the isolation equipment components must be a permanent component specification.

According to the IEC specification, whether the mechanical resistance of the internal components will jump off when the circuit breaker is simple and convenient for the general consumer to test (because there is no basic test equipment, it is impossible to know whether the circuit breaker is faulty, Do the action of jumping off the isolation). Therefore, the IEC stipulates that manufacturers of circuit breakers are manufactured all over the world. For industrial type circuit breakers, whether MCCB or ELCB, that is, a case circuit breaker or an earth leakage circuit breaker, there must be a trip test button switch connecting the internal tripping components. As the basic component of the test, the inverted L-shaped plate can not cover the trip test button switch in principle for testing, and if it is a leakage circuit breaker, it must add a plane reserved surface to facilitate test. The lock and the inverted L-shaped plate and the elongated fixed box assembly are adjustable so that the upper, lower, left, right, high and low are adjustable, and the reserved hole is provided on the inverted L-shaped plate. The actual situation that cannot be solved by the patents of No. 105213785, No. 105214529, No. 105215789, and No. 106200125 can be solved. This seems to be simple. It is very difficult to solve this problem. It must also have the understanding of the actual product structure of thousands of manufacturers around the world, as well as the changing trends and the principles and regulatory requirements and correction directions of the regulations. According to the analysis, the combination of the inverted L-shaped plate and the lock is integrated with the lock, and the combination of the long fixed box can solve the problem that the industrial type circuit breaker must be equipped with a safety lock, and solve the conventional motor. A person familiar with power engineering skills who cannot perform functions with prior art.
