Abstract

The present invention, an integrated fire alarm emergency power isolation device, aims to improve upon existing techniques that fail to meet the requirements set forth by the regulations of the Ministry of Economic Affairs' Energy Bureau for user electrical equipment. Conventional molded-case circuit breakers typically trip when there is a fault in the circuit or equipment. Moreover, commonly used non-trip element switches or instantaneous electromagnetic switches cannot provide fault-tripping protection for the circuit and equipment. Both of these widely used switches do not meet regulatory requirements. The isolation device, when in the maintenance position, should be lockable, and in normal operation, the isolation device for the fire pump and on-site standby generator should be lockable when in the closed position.

The present invention of the integrated fire alarm emergency power isolation device addresses the aforementioned issues with the following key technical features: combining a set of molded-case circuit breakers with lockable positions for both on and off states, along with a set of non-trip element switches or circuit breakers that can be locked in the closed position. This combination allows for normal operation with the ability to open and lock, and during circuit or equipment faults, enables fault-tripping and power isolation. In the event of a fire, the non-trip element switches forcibly close, ensuring uninterrupted power supply to the fire protection equipment, thus meeting regulatory and safety requirements.

Description

Complete set of fire alarm emergency electrical isolation equipment

This invention of a complete set of fire alarm emergency electrical isolation equipment can improve the knowledge and technology that the fire alarm emergency electrical isolation equipment cannot meet the requirements of the Ministry of Economic Affairs Energy Bureau's user electrical equipment installation rules and regulations. This is because the general molded case circuit breaker will trip when a line or equipment fault occurs, and the general non-tripping element switch or instantaneous excitation switch cannot achieve fault tripping protection for the line and equipment. The above two commonly used switches in the knowledge and technology cannot meet the following requirements of the law. The isolation device can be locked in the start position during maintenance and in the normal state between the fire pump and The isolation equipment of the on-site standby generator should be lockable in the closed position; this creative integrated fire alarm emergency electrical isolation equipment device can solve the above problem. The main technical feature is to combine a set of modular circuit breakers with lockable open position and a set of non-tripping element switches or circuit breakers that can be locked in the closed position. The lock can be opened and closed during routine maintenance, and can be closed and locked when normal. When the line or equipment fails, it can trip and disconnect the power when the accident occurs. When a fire occurs, the non-tripping element switch is forced to close, so that the fire equipment does not need to worry about power supply, so as to meet the requirements of laws, regulations and safety.

In the prior art, the isolation device in the circuit that supplies power to the motor to drive the fire pump generally uses a molded case circuit breaker as a trip-off isolation protection for the fault current on the line. When the fire pump equipment is overloaded, the isolation device switch also provides trip-off isolation protection for the equipment overload current. The above is the current general protection measure setting for power circuits. When the on-site standby generator is used as a backup power source, according to the regulations, the standby generator should be equipped with an isolation device that can be locked in the start position. In addition, Article 841, Paragraph 2 of the User Electric Equipment Installation Regulations stipulates that when the on-site standby generator is used as a backup power source, its wiring should comply with the emergency power circuit regulations of Article 976, Paragraph 2, and the isolation device should be lockable in the closed position. In addition, Article 165 of the regulations stipulates that backup generators should be equipped with double-throw automatic transfer switches (ATS), or electrical and mechanical interlocking devices between switches, which can simultaneously start and cut off the power supply originally supplied by the power company when the backup generator is in use. However, this does not apply to those that are connected with the consent of the power company. Known technical isolation equipment cannot meet the requirements of the above regulations.

In the current knowledge and technology, the protection equipment in the power circuit generally includes low-voltage air circuit breaker ACB, low-voltage molded case circuit breaker MCCB (same as Japan's non-fuse circuit breaker NFB), fuse FUSE, gate switch KS, etc. as isolation equipment between the line and the equipment. According to domestic electrical habits, molded case circuit breakers are used when the current is within 800 amperes, and when the current exceeds 800 amperes, Low-pressure air circuit breakers are used for currents above 100 amperes, while distribution boxes or safety switches or safety switches with fuses or fuse sets are only used in special places. The above products are more commonly used abroad, and molded case circuit breakers and low-pressure air circuit breakers are more commonly used in China. Both of the above products cannot meet the electricity requirements of the regulations alone, so this creation can solve the requirements of the regulations.

According to Article 165-6 of the Regulations on the Installation of Electricity Equipment for Users of the Bureau of Energy, Ministry of Economic Affairs, backup generators should be equipped with dual-throw automatic transfer switches (ATS), or electrical and mechanical interlocking devices between the switches, so that the power supply originally supplied by the power company can be started and stopped at the same time when the backup generator is in use. However, this does not apply to those who have agreed to connect with the power company. Generally, manufacturers of automatic switching switches have molded case circuit breakers with or without tripping elements. The differences are due to different considerations. When isolation devices such as molded case circuit breakers or air circuit breakers have tripping elements, they can protect against line fault currents and equipment overload currents, but they cannot force power supply in an emergency. Circuit breakers without tripping elements can force power supply, but they lack protection for lines and equipment. Skilled isolation devices cannot have the above functions at the same time, so they cannot meet the functional requirements of regulations.

In accordance with the requirements of the Ministry of Labor's Occupational Safety and Health Act, the Executive Yuan's Labor Council's Labor Safety and Health Research Institute published the "Electrical Safety Technical Data" in a research report led by Su Wenyuan in 1999, which pointed out: "Electric shock accidents have always been one of the main causes of accidental injuries to workers, and should be avoided as much as possible to protect the safety of workers. The main reason for electric shock accidents is that businesses and workers lack awareness of electrical safety, resulting in unsafe environments and unsafe behaviors at work. Potential hazards." There are two main types of common electrical safety disasters. The first is from mechanical equipment that uses electricity, and the second is negligence in electrical operations. In order to remedy the lack of knowledge of electrical safety among businesses and workers and prevent hazards from electrical operations, Article 45 of the "Labor Safety and Health Facilities Rules" further mandates that employers use electrical machinery and equipment with safety facilities. That is, for machines that use power and are significantly dangerous, an emergency brake device with obvious signs should be installed at an appropriate location to immediately cut off the power and connect with the brake system to quickly stop the operation of the machine in an emergency. In addition, to prevent hazards from electrical work, when working during a power outage, Article 254 of the "Labor Safety and Health Facilities Rules" stipulates that when an employer is engaged in laying, constructing, inspecting, repairing, painting, etc. of a circuit, circuit support, or work near the circuit after the circuit is open, the employer should, after confirming that the circuit is open, open the circuit and "lock" or mark "power supply prohibited", "power outage in progress", or set up facilities for monitoring by surveillance personnel during the work. The first type of disaster from electrical machinery and equipment mentioned above is caused by the fact that most people do not have enough knowledge of the principle of electrical safety power cutoff. Although Article 254 of the "Labor Safety and Health Facilities Rules" further stipulates that the circuit should be "locked" during operation, so far, the "locking" regulations are often empty talk and have not been actually implemented. According to the international electrical regulations NEC.422.31. (430.102) (440.14), the branch switch or circuit breaker used as an isolation device should have a locking device. The isolation device is located within the visible range of the electrical equipment or can be locked when the circuit is open. The locking device mechanism should be placed in an appropriate position. The principle and purpose of the regulations are to prevent the mistransmission and reverse transmission of power (without affecting public safety!):

1. Private indoor distribution panels do not need to be locked.

2. Electricity in public places must be locked.

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

4. Do not lock the door if there is a dangerous situation after locking it!

The locking device is to prevent the wrong power transmission, reverse power transmission, etc. Because there are invisible conditions that may cause danger, people want to lock the switch during maintenance to ensure safety. In view of this, switch manufacturers around the world all produce related products. These include external hanging type, internal key type, etc. Similarly, there are mandatory regulations and penalties in OSHA (Occupational Safety and Health Standards), Fire Law Regulations, etc.

According to the fire regulations of the Ministry of the Interior Fire Department, when a fire occurs, there must be power supply to firefighting equipment, such as fire alarms, broadcasting systems, emergency elevators (more than one), smoke exhaust fans, blowers, fire pumps, foam pumps, sprinkler pumps, water pumps and generator isolation devices. The closed position should be locked to ensure the safety of life and property.

According to the Ministry of Economic Affairs' Electricity Industry Act, the regulations on user electrical equipment installations require the following:

Article 146-14 The isolation equipment of fixed electrical appliances shall be handled in accordance with the following regulations:

It shall be located within the range of the fire pump load equipment and away from other buildings or other fire pump power isolation equipment, and at a sufficient distance to prevent accidental simultaneous operation. (2) When the on-site backup generator is used as a backup power source, its wiring shall comply with the emergency power circuit regulations of Article 976, paragraph 2, and the isolation equipment shall be lockable in the closed position. Amendment to Article 841. The isolation equipment currently available on the market cannot effectively meet the above requirements.

In summary, an isolation device switch must comply with the requirements of the Electricity Law, the Labor Inspection Law, and the Fire Protection Law. The most basic requirement for a switch is to have protection against overload current and fault short-circuit current. During maintenance, it is necessary to confirm that the switch can be effectively locked in the off position to prevent accidental operation and closure causing industrial accidents. Similarly, important equipment such as fire protection and emergency conditions (such as life support systems) must be locked in the closed position to prevent accidental power off and start-up causing casualties and industrial accidents. Isolation equipment for standby generators and power supply to motors driving fire pumps must also be locked in the closed position. The device can be locked, and leakage circuit breakers and components with overload tripping are prohibited. That is, when a fire occurs, it is necessary to ensure that the power supply to the fire fighting and emergency equipment will not be cut off to ensure safety. The above practical requirements are generally not met by molded case circuit breakers or low-voltage air circuit breakers. Isolation devices without tripping components such as instantaneous excitation switches, gate switches, fuse sets, safety switches or safety switches with fuses cannot meet all the requirements of regulations. This creative complete set of fire alarm and fire emergency electrical isolation equipment can solve the above problems.
