Abstract

The utility model discloses an automatic draining device for a cable trench of a transformer station, which comprises the following components: a controller, a water draining pump and a float ball water level switch. The water draining pump and the float ball of the float ball water level switch are provided in a cable trench water collecting well. The controller is composed of the following components: a singlechip microcomputer, a power supply module, an amplification module, a photoelectric insulation driving module and an indicating module. The control switch of the float ball water level switch is connected with an input end of the singlechip microcomputer. The output end of the singlechip microcomputer is respectively connected with the amplification module and the indicating module. The output end of the amplification module is connected with the input end of the photoelectric insulation driving module. The output end of the photoelectric insulation driving module is connected with the water draining pump through an electromagnetic valve. The singlechip microcomputer is also connected with a control center through a GSM/GPRS communication module. The automatic draining device for the cable trench of the transformer station has the following advantages: greatly improving flood control capability in the transformer station, effectively ensuring safe operation of the equipment, reducing power resource wastage, reducing cost and stabilizing safe operation management of the electrical network.

Description

A kind of transformer station cable trench self-draining arrangement

Technical field

The utility model relates to a kind of cable trench dewatering installation, especially relates to a kind of transformer station cable trench self-draining arrangement.

Background technology

At present, transformer station all realizes unwatched collection keyholed back plate reason, as the infrastructure of transformer station; Cable trench is because physical features is lower, and the easiest ponding when flood situation takes place is if draining in time; Can cause the dielectric strength of cable to descend; The threat of switch trip or large-area power-cuts needs personnel to arrive on-the-spot draining, wastes time and energy and increases maintenance cost.

Summary of the invention

For addressing the above problem, the purpose of the utility model provides a kind of transformer station's cable trench self-draining arrangement esy to use, safe and reliable.

For realizing the foregoing invention purpose, the utility model adopts following technical scheme:

A kind of transformer station cable trench self-draining arrangement; It comprises controller, drainage pump and ball float water level switch; The ball float of drainage pump, ball float water level switch is arranged in the cable trench collecting well; Controller is made up of single-chip microcomputer, supply module, amplification module, photoelectricity isolation drive module and indicating module; The gauge tap of ball float water level switch is connected with the input of single-chip microcomputer, and the output of single-chip microcomputer is connected with amplification module, indicating module respectively, and the output of amplification module is connected with the input of photoelectricity isolation drive module; The output of photoelectricity isolation drive module is connected with drainage pump through an electromagnetic valve, and single-chip microcomputer also is connected with Surveillance center through the GSM/GPRS communication module.

Described transformer station cable trench self-draining arrangement, the single-chip microcomputer input of its controller are connected with a manual switch.

Owing to adopt aforesaid technical scheme, the utlity model has following superiority:

This transformer station's cable trench self-draining arrangement, it adopts the ball float water level switch to obtain the water level in the cable trench collecting well, when water level is higher than the setting high water level; Start drainage pump and carry out draining, when water level was lower than the setting high water level, drainage pump was in holding state; Make personnel need not the scene, can carry out draining, improved the flood control capacity in the transformer station greatly; Safe operation to equipment has increased firm barrier; Reduce the electric power resource waste, reduced cost, stablized the electric power netting safe running management.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

Through the accompanying drawing example technical scheme of the utility model is done further explain below.

As shown in Figure 1; This transformer station's cable trench self-draining arrangement; It comprises controller, drainage pump and ball float water level switch; The ball float of drainage pump, ball float water level switch is arranged in the cable trench collecting well, and controller is formed by single-chip microcomputer, amplification module, photoelectricity isolation drive module, indicating module and for the power module of entire controller power supply, and the gauge tap of ball float water level switch, a manual switch are connected with the input of single-chip microcomputer; The output of single-chip microcomputer is connected with amplification module, indicating module respectively; The output of amplification module is connected with the input of photoelectricity isolation drive module, and the output of photoelectricity isolation drive module is connected with drainage pump through an electromagnetic valve, and single-chip microcomputer also is connected with Surveillance center through the GSM/GPRS communication module.

Water level rises in the collecting well, and the ball float of ball float water level switch floats thereupon, in water level arrives single-chip microcomputer during predefined high water level; The gauge tap of ball float water level switch sends signal and sends in the single-chip microcomputer; After single-chip microcomputer was handled, the control signal of single-chip microcomputer output opened the electromagnetic valve energising after amplification module amplification, photoelectricity isolation drive resume module; Drainage pump begins draining, and the indicator lamp of indicating module is lighted simultaneously; Along with drawdown in the collecting well; The ball float of ball float water level switch descends thereupon, and during predefined low water stage, the gauge tap of ball water level switch sends signal again and sends in the single-chip microcomputer in water level arrives single-chip microcomputer; After single-chip microcomputer is handled; The output control signal is closed the electromagnetic valve outage, and drainage pump stops draining, and the indicator lamp of indicating module goes out.

The hand switch that can also connect through the input of single-chip microcomputer carries out forced drainage.

Single-chip microcomputer carries out bidirectional transfer of information through GSM/GPRS communication module and Surveillance center, makes Surveillance center carry out telemonitoring and control to the running status of SEA LEVEL VARIATION situation and drainage pump in the cable trench.
