Control and display integrated device capable of displaying self-stripping power state

The present invention is a control and display integrated device capable of displaying the state of self-tripping electric energy, which can improve the traditional high-voltage switchboard without knowing the actual state of the working electric energy of the tripping circuit, and can improve the complicated wiring method of the instrument room unit of the traditional high-voltage switchboard. In a standardized combination mode, it can be easily installed and maintained, and can be assembled in a standardized manner, which can reduce costs economically and improve the quality of electricity.

The combined construction method of a high-voltage switchboard generally consists of five units: an enclosure panel, a busbar unit room, a circuit breaker unit room, a cable unit room, and an instrument room unit. The instrument room unit is generally not standardized. , Other units can be standardized, and the instrument room unit is the core of the electrical control of the high-voltage switchboard. Each case is different because of the protection of the line and load equipment. In addition, the protection methods and functional requirements are not the same, so every case is not universal, resulting in the inability to standardize the manufacturing process, the configuration and wiring methods, and the inability to achieve standard uniformity, and the inability to enhance its economic benefits and improve maintenance. The convenience and safety of electricity use are improved.

In the Xiyou high-voltage switchboard, in addition to the external metal box, the main internal equipment includes high-voltage circuit breakers, grounding switches, current transformers, protection relays, voltage comparators, lightning arresters, Charged display devices...etc. have different construction methods according to customer's individual requirements. The control display unit of the instrument room unit basically has not been well planned.

The high-voltage circuit breaker panel has three actions, one is to close ON when power is on, the other is to turn off when power is off, and the third is to trip and isolate the accident when a fault occurs. Generally, the instruction for driving the circuit breaker to trip comes from the protection relay, and the protection relay is connected to the sensing device, in which the current comparator CT detects whether there is an overload or short circuit accident, and the voltage comparator PT detects whether there is an overvoltage Or low voltage conditions, the zero comparator ZCT detects whether there is grounding, or excessive temperature, abnormal frequency... etc. The sensing device provides the detection value as the basis for the activation of the protection relay, and then Open the circuit breaker to isolate the accident point. In the current high-voltage power distribution system, many accidents cannot effectively isolate the accident point and cause the circuit breaker to trip. Many of the reasons are due to the power failure of the trip circuit in the system. At present, in the high-voltage power distribution system on the market, the trip circuit power supplies used are generally divided into DC working power supplies and AC working power supplies. The DC working power supply generally uses the battery pack as the working power supply of the trip circuit, and the AC working power supply generally uses the capacitor tripping device CTD as the main. At present, the tripping methods of high-voltage circuit breakers are generally divided into two types, one is electric, using an internal action coil, and the other is mechanical tripping. In order to avoid the failure of the operating power supply of the trip circuit, the trip circuit cannot operate normally to isolate the accident point when an accident occurs, it is necessary to design a device that displays the power state of the trip circuit, and there is currently no relevant design on the market. product.

When the power supply (distribution) system, the tripping circuit of the control power supply in the high-voltage circuit breaker panel, the working electric energy is disabled, resulting in the failure of the system when an accident occurs because there is no effective working power supply, the circuit cannot be broken The power-off and tripping action of the device can isolate the accident and even cause major losses such as blackouts. In these cases, the high-voltage circuit breaker (H.V.CB) or UHV vacuum circuit breaker CGIS or gas-insulated equipment GIS accepts the instruction of the protection relay (Relay) as whether to trip high Voltage breaker to isolate the source of the accident. Therefore, if the circuit breaker cannot be tripped immediately when a short-circuit accident occurs in a certain business unit (receiver) as scheduled, it will cause damage to the high-voltage circuit breaker (HVCB), which will affect the main power supply main line to supply power to other businesses. Unit (receiver), causing chain industry losses. Whether the high-voltage circuit breaker can trip in time is controlled by whether the protection relay (Relay) can issue instructions immediately. Therefore, when there is a problem with the working power supply of the protection relay, the protection relay will not operate; when the protection relay does not operate, the high-voltage CB will not operate when an accident occurs, and it is impossible to isolate the accident of the business unit. Point, cause a serious secondary accident, and even affect the tripping of Taipower's power feeder. Don't be careful!

The high-voltage circuit breaker switchboard circuit control device mainly based on high-voltage circuit breakers, according to its functions, includes: the state of a circuit breaker switch contact is closed or not, and the control and display part includes power-on ON, start-off OFF, fault trip, etc. ; A sensing device unit such as current sensing device CT (commonly known as current comparator), voltage sensing device PT (commonly known as comparator), ground sensing device ZCT, temperature sensing device, frequency sensing device... Etc.; a protection relay unit, the protection relay unit receives the results of the sensing device and inputs it into the protection relay, according to the requirements of the protection coordination of its power distribution system, determined by the calculation of the internal electronic circuit and the microprocessor, according to requirements Set the required action to make the internal contact active or not; a display status unit, currently a collective meter is generally used, the display status unit is input to the collective meter based on the result of the receiving and sensing device, and is processed by internal electronic circuits and micro-processing The calculation judgment of the device shows its voltage and volt value V, current ampere value A, power meter KW, reactive power meter KVAR, power factor meter COS, temperature ℃... etc.; a control state unit, such as a circuit breaker The ON button switch with the main contact turned on, the OFF button switch for opening and closing the main contact of the circuit breaker. After the circuit breaker is tripped, the fault trip lamp flashes and stops. Reset PB...... etc.; External power supply unit, the external power supply is generally divided into Voltage source such as PT voltage source power source, uninterruptible power system UPS, generator... etc. DC power part such as battery pack BAT, solar energy... etc.; a connection unit, which is electrically connected to the circuit breaker and the instrument room Units, sensing device units, protection relay units, etc., integrating all the above functions can effectively solve the shortcomings of traditional high-voltage switchboard instrument room units.

As explained above, a high-voltage circuit breaker panel, generally speaking, prevents accidents from tripping and tripping the actual state of the trip circuit electrical energy is generally ignored, leading to many accidents. In addition, in the high-voltage power distribution system, the high-voltage circuit breaker itself does not have the function of self-tripping like the low-voltage circuit breaker. Therefore, it is urgent to improve the high-voltage circuit breaker switchboard with self-trip function to prevent accidents. Especially when all external power sources can become the working electric energy of the trip circuit, the reliability of the system power supply will increase. And if it is supplemented by the current source of the power loop itself, the stability of its power supply system can be guaranteed. Such an integrated control and display device capable of displaying the state of self-removing electric energy can improve one of the defects of the previous high-voltage switchboard. Especially if the status of the switchboard can be monitored on the panel, it is better, and the current commonly used high-voltage circuit breaker panels do not have this function.

The connection unit is electrically connected to the internal circuit control unit, and the internal circuit control unit is electrically connected to the front panel of the combined electrical instrument room, but the current commonly used high-voltage circuit breaker panel does not have this function. In the learned skills, there is no effective plan for the internal power distribution equipment of the high-voltage switchboard, resulting in messy configuration, chaotic signs, and complicated wiring... etc., a control display integrated device that can display the state of self-removing power can solve it The problem Program.

In the learned skills, the trip circuit power supply of the high-voltage circuit breaker switchboard has always been a neglected part. Especially for the actual state of its working electrical energy, it is impossible to clearly understand all its conditions, nor can it be tested on site or automatically detected and tested. Therefore, when an accident occurs in the system, because there is no working power, the main contact of the high-voltage circuit breaker cannot be de-energized and the accident can be isolated when the accident occurs. If the external power supply and the voltage source of the voltage comparator PT are disabled, and the power is not used The electric energy of the current source in the system loop, the relevant electric energy state is not displayed on the display panel, which makes it difficult to interpret. These problems are the lack of functions in all the conventional techniques, and there is an urgent need for improvement.
