The invention relates to a temperature control device and in particular relates to a constant-temperature device in a direct-current chamber of a power system. The constant-temperature device comprises a cast-iron radiator (1), a temperature controller (2) and a relay (3), wherein an electric heating tube (4) is mounted in a water inlet in the bottom of the cast-iron radiator (1) in a sealing manner; an input end of the temperature controller (2) is connected with a temperature sensor (6) which is mounted on the side surface of the cast-iron radiator (1); an output end of the temperature controller (6) is connected with a coil of the relay (3); a contact of the relay (3) is connected in series in a circuit of the electric heating tube (4); the electric heating tube (4) is powered by a 220V power supply. The constant-temperature device is reasonable in design; by using waste or obsolete cast-iron radiator, the constant-temperature device has the main advantages of simplicity, practicability, large heat radiating area, long heat supply and heat preservation time, durability and economy.
Description
technical field [0001] The invention relates to a temperature control device, in particular to a constant temperature device used in a DC room of a power system. Background technique [0002] The DC system is very important in the operation of substations and switchgear equipment. If there is no DC system, the protection device of the equipment will not be able to function, and the equipment will not be able to operate normally. The main component of the DC system is the lead-acid battery. The battery has high requirements on the indoor temperature, usually between 10 and 30°C, otherwise the battery life will be greatly reduced. All the shelters are built in the basement and have almost no heating. In winter, the DC room of the switching station is mainly heated by U-shaped electric heating tubes or throttle electric heaters, but the U-shaped electric heating tubes are relatively simple, the heat dissipation area is not enough, and the heat provided is limited; throttle ele...
