A high-voltage and large-capacity electric heating heat storage control device that meets the requirements of electric power

Abstract

The invention relates to a high-voltage high-capacity electric heating and heat accumulation regulation and control device adapted to electric power requirements. The device includes a 433 sender, a multichannel collector, a direct current power supply, an intelligent electric quantity metering device, a repeater and a remote monitoring center; the multichannel collector collects temperature information of a high-voltage sectioning switch and a voltage division breaker, sends the temperature information to the repeater through the 433 sender, is connected with the 433 sender; and the intelligent electric quantity metering device is used for detecting the voltage, current, environment temperature and time parameter of a line where the voltage division breaker is, gives an alarm when an abnormal state is detected, and sends to the repeater. The advantages are that according to user requirements, grid-connected access or switching of an energy conservation and heat accumulation mode can be performed at any time, and seamless access of a power grid is realized; capacity extension and reconstruction can be performed according to actual needs of the user, and setting and monitoring of a working mode are performed for capacity extension as needed; and a piezoelectric induction wireless sensor is adopted to solve the problem of ultrahigh voltage temperature measurement.

Description

technical field [0001] The invention relates to the field of high-voltage and large-capacity electric heating and heat storage, in particular to a high-voltage and large-capacity electric heating and heat storage control device that meets the requirements of electric power. Background technique [0002] "High-voltage and high-power electric energy storage furnace" is a new type of high-power heat source that uses low-peak electricity or abandoned wind power to adopt solid heat storage. The equipment does not need a transformer and can work directly at a voltage level of 10kv to 66kv. The input power of a single unit can reach 100,000 kilowatts, and the heat storage capacity can reach 800,000 kWh. The equipment can completely absorb and abandon wind power, realize the 24-hour continuous heating capacity in large-scale and ultra-large-scale urban areas, and can completely replace the widely used coal-fired, gas-fired, and oil-fired boilers at present, without any waste gas, wa...
