Embodiment Construction

[0014] Such as figure 1 As shown, the rectifier transformer cooling system includes a rectifier transformer. Five sets of oil-air coolers are installed on the rectifier transformer. Each set of oil-air cooler control cabinets is equipped with three positions: stop, work, and backup. The rectifier temperature sensor The controller is connected, and the controller is connected with five groups of relays, each group of relays controls the stop, work and standby positions of a group of oil-air cooler control cabinets; there are four groups of rectifier temperature sensors.

[0015] Based on the cooling method of the rectifier transformer cooling system, a group of oil air coolers is selected for standby operation, and the temperature measured by the rectifier transformer temperature sensor is within the set temperature range, and the controller controls four groups of oil air coolers except for standby operation through relays. The coolers work sequentially; when the temperature m...

Abstract

The invention discloses a rectification transformer cooling system and cooling method. The rectification transformer cooling system comprises a rectification transformer, the rectification transformer is provided with five oil-air coolers, and a control cabinet of each oil-air cooler is provided with a stop position, a work position and a backup switching position. The system is characterized in that rectification variable temperature sensors are connected with a controller, the controller is connected with five relays, and each relay controls the stop position, the work position and the backup switching position on the control cabinet of one oil-air cooler. By using the technical scheme, work or stop of the oil-air coolers can be automatically controlled according to the temperature of the rectification transformer, the work quantity of the oil-air coolers is timely and rapidly adjusted, the temperature of the rectification transformer is efficiently adjusted, rapid reaction can be given under emergent conditions such as temperature abnormal change and the like, and loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of rectifier transformer cooling and cooling, and in particular relates to a rectifier transformer cooling system and cooling method. Background technique [0002] The rectifier transformer heats up seriously during operation. The loss of our company’s electrolytic rectifier transformer can reach 120kw, and the loss is converted from electrical energy into heat energy, which is dissipated into the surrounding environment in the form of heat. The temperature in summer is particularly high, and a large amount of heat is directly discharged. It will affect the surrounding environment. In addition, the temperature of the rectifier transformer is too high to affect its life, so cooling treatment is required. [0003] At present, there are four sets of oil-air coolers on a single rectifier transformer. When the oil-air cooler control cabinet is designed, each set of switches has three positions: "stop", "work" and...
